An older friend and co-worker mentioned he had worked before WWII at Century Carburetion in LA. The produced the propane/butane carburetors that Hall Scott used. These were the biggest dry gas carburetors they made. They used linkage and a barrel valve for fuel control. Jack mentioned that a fellow would show up and buy a box load of their barrel valves. The individual's name was Stu Hillborn and he was using them on his fuel injection systems for race cars.
Finally, my curiosity about the Hall-Scott has been satisfied. Danny Rios, the guy who taught me to drive a Cummins 335 5x4 tractor in 1972, used to brag about his Hall-Scott, butane engined Autocar that would blow all the other trucks, and even Greyhound busses away up the Grapevine back in the fifties. He said that the stack put out a two foot blue flame that would light up the night when it was pulling hard. Thank you!
@@toddamtmann3528 , with a decent intercooler , turbo or supercharger, four valve lean burn cylinder head, a beefed up crankshaft and connecting rod, 98 Octane Premium Petrol, quite a lot. Look at the latest lorry diesel engines from Scania ,Volvo, MAN ,and Mercedes Benz that comply with Euro 6 Emission Standards ,in order to do so, they have no alternative but use very high compression ratios.
No there is - it's called boost. Essentially you can make the same power at half the displacement. Why would you have a 30 liter engine when you can have a 15 liter engine that makes the same power and torque, is 1/3rd the size and uses about 1/3rd the fuel and about 200% lighter allowing greater payload? For example, a 15 liter Cummins with 35PSI boost makes 600hp and 2000ft/lbs torque at half the cubic capacity. That means off boost the engine is only 15 liters. A 30 liter engine is always a 30 liter engine so always consumes fuel like a 30 liter engine.
Yes I know about increasing an engines power with a gear or an exhaust driven blower ,look at Roller,s Merlin 26 litres in 60 -70 Series Form 1600to 1750 ponies, the 130-140 Series burning 115\145 grade petrol 2,030 ponies. Turbo Compounding is another means of increasing a engines power without increasing its fuel consumption and internal stress. All petrol and diesel engines including the one in your car ,use the energy of the burning fuel once, with turbo compounding that wasted energy is recovered via an exhaust driven turbine coupled to the crankshaft via gears and a fluid drive . You are using the energy in the burning fuel not one but twice or three times. It works!!!! How do you think Trans Polar airline travel was made feasible in the early 1950,s ?. Not long after World War Two engineers at Curtiss Wright of Dayton Ohio modified an R-3350 Duplex Cyclone Radial, the same engine that powered Tibbet,s Boeing B-29 Superfortress 'Enola Gay' to end World War Two. A standard model R-3350 of 2,500 ponies had a new rear section fitted with three exhaust driven turbines at '12 ,4,and 8' o clock . That same engine same fuel consumption on the test stand 3,250 ponies, for example an early model Pratt&Whittney R-4360 a much bigger heavier engine 3,000 ponies, for the turbo compounded R-3350 in 1947-48 a serious pony count. That year 1947 'Truculent Turtle' a US Navy Lockheed P2V Neptune Patrol Bomber circumnavigated the world with a few exercises in flight re-fuelling , an aviation feat all down to the Turbo Compounded R-3350 Duplex Cyclones exceptional fuel consumption. @@ThePaulv12
This is the only channel on RUclips that focuses solely on the history, specs and comparisons of so many different Internal combustion engines. Very impressive. Keep up the good👏
You got to give it to them that was alot of horsepower at that time. Now they are at 600 horses but I am sure the torque is much more and the weight is much less
I am a retired truck mechanic and I have always been impressed with the early engineers and manufacturer's how smart they were to be able to figure all that stuff out they didn't have computers to tell them they had to have some Sharpe minds.
And likely why there's so much garbage being sold as high tech, everybody relying on computers to do their thinking for them.. the result is, garbage, short lived products..too bad.
@@h8troodoh Thanks for the reply Mitch you hit the nail on the head those old trucks were sure easier to work on and I think they were much more reliable. I twisted wrenches for close to 55 years and the troubles started a little over 20 years ago and they steadily got worse with more electronics and stricter emissions standards.I am 74 years old I retired a little over a year ago and I sure don't miss the hassle of working on that new stuff.
@danhuttinger5040 the thing is,too many electronics, period. Take me back to my old 250 6 banger Chevy engine.. it was a happier time in mine and likely everyone's lives.. take care my friend, enjoy retirement..
Because there were real men & women not children that age says there adults. Pvt non ASE gas engines so far for 12 years I learned what I know from actually doing some college family helped too.
In 1966, when I was just 15, I remember riding a mid-engine powered Crown school bus that had this really cool sound. I asked the driver what kind of engine it had underneath. He told me it was a Hall-Scott 590. We were out dropping off students in a remote area and I asked him what it would do. He floored it and that bus accelerated like a car. He backed off at 65, not wanting to be too obvious, but we both smiled. I'm not sure which impressed me more... that wonderful sound, or the raw power. Great engines. Particularly at a time when gasoline was around 30 cents a gallon.
Saw one oñce in a bus. It was mounted on it's side under the bus. I had never heard of one previously. I think it was an inline six & the time was between 1964-73. Working in a GM C shop at the time.
These became obsolete right before I started driving truck… if’n I was born 10 years earlier, I could have gotten my hands on one of those. Magnificent!
Finally!! Thanks!! I have worked on a number of 400's and own a 400 in a 46 Kenworth. EVERY Hall Scott motor was bench tested, dynoe'd, balanced and rebalanced. That was one of the reasons they lasted so long. The dual plug feature was a requirement for any power plant used in fire suppression. Another significant placement of the Hall Scott engines was in oil field work, where they ran off of blow off gas and natural gas. At one point, Oshkosh had a manifold set up for their Hall Scott powered US Air Force tugs that had 2 Holley 4 barrell carburetors. Nice piece. I wish I had have kept my promise to you and provided you with more information and video content. My apologies.
That’s very true about balancing.. it completely changes an engine and certainly would help it last longer. As said in the video, it wasn’t about price- that’s the key difference I guess- you cannot have the best product at a discount price.
I actually suggested doing a Hall Scott video and appreciate the excellent job you did. I've been in trucking for a long time and have been into internal combustion since I was a kid. I agree about H-S not developing a diesel engine, truly a missed opportunity. All they really needed to do was convert the existing gasser over to a bowl in crown piston design and flatten the combustion chamber in the head. The engine was so overbuilt that it would more than handle the cylinder pressures.
no need to flatten the combustion chamber. Just build a bigger dome in the piston crown. Having the opposed valve head and hemispherical combustion chamber would have been very efficient. And given the two spark plug ports, one could have easily been used for an injector and the other a glow plug port. I have a 400 in a 46 Kenworth and have worked on a number of Hall Scott power plants
@@V8Lenny not as efficient, but would have worked with minimal re tool in the plant. From a production cost standpoint, hemi would work. From a engineering standpoint, flattening the parts would work best. One of you is Hall, the other is Scott lmao
@@HeyItsJonny but today when LNG engines are becoming popular, gasoline engines would be better starting point, now they are all converted from diesel, not the most efficient.
My fire department had a twelve cylinder Hall Scott powered aerial ladder truck. The sound produced by the engine was mechanical music, it was my favorite truck to drive.
In 1970 I worked on a ranch in South Central Idaho that used 2 or 3 Hall-Scott V12 engines for irrigation wells. They would idle all summer long bringing up water from 300 feet below. They had dual ignition systems and a the mechanic could change spark plugs while in operation. We got some of the best tasting water from one well and another had so much sand it wasn't drinkable.
I worked for a school district in the mid seventys. Half of the 79 passenger school busses ( crown coach ) were powered by Hall Scott A 590 motors. Single overhead cams, the machine work was second to none. The first time I removed valve cover I was pleasantly surprised by the finish of the parts. Gorgeous comes to mind. Super reliable motors. Still miss them and the music only 590 cu inches can play. .....
I was 3 years old when we moved to a mountainous area near Los Angeles. A wildfire started on a hot Summer day and fire trucks arrived, strung up hoses and began fighting the fire. A very big pumper truck parked by the corner of our street had its hood open with the engine running the pump system. That engine fascinated me, and my dad said it was a Hall Scott. I can still remember the sound it made. That was 67 years ago.
It was great to hear somebody else talk about a Hall Scott engine. I only heard 1 other person talk of them my grandfather. He said only GMC came close to them.
Very good video. My Dad worked on Hall Scott's in the early 1960's on truck used in the logging industry. Had these engines. He always talk about the HP and torque of these engines and how the outperformed early diesel engines in trucks. Thanks for sharing. I just subscribed to your channel. Take care, EM.
When I was a kid our local fire department had a Kenworth tanker truck with with a six cylinder Hall Scott in it, was a great sounding engine and they used it up until the late '70s. A friend of mine had a fairly large cabin cruiser built in the late 1920's that had a pair of Hall Scott engines for power, not sure but think they were the smaller versions and they were still powering that boat into the 1980s. I was around them several times when the owner was tinkering with them and they too were great running and sounding engines. Thanks for the video!
I enjoy the way you go down the rabbit hole on our behalf. I had encountered the name Hall Scott a few times while looking in to weird old engineering, but I have never done any more research, and then you serve up a fabulous history leason. This is just perfect.
I was glad to hear you mention the cam design work Hall did for Duesenberg as it was vital in the development of high speed engines and was copied by all the racing engine builders of the time. A Duesenberg with a Hall designed cam won the French Grand Prix in 1921.
Blown away by all the stories shared here in the comments! Man the VisioRacer followers make the comments as interesting as the videos and that's no small feat! Cheers to you all and hope you all are doing well 👍
Very interesting ... My dad was a propane distributer back in the 1940s to 1960s and he got Crane Mills, a local logging company in Corning and Paskenta, CA to get their logging trucks to run Hall Scott s . They ran about 12 to 15 of them for years back when diesel power was very lacking. I don't know what size the engines were, but they also ran with hydro-tarders which was a method of using water for braking going down hill loaded. AND they were loaded, they ran 12 foot bunkers and who knows what weights they carried bringing a lot of virgin timber out of the coast range mountains. It was all on private roads, so no load weight restrictions. I was too young to know much about it all at the time, but my older brother (now decesed) did work for them for a while running a water truck over the logging roads on the night shift. I did forget to mention these logging trucks ran on propane. Hydro-tarders, now maybe that is a new subject for a new posting. In the logging trucks they carried a 500 gallon tank for the water to use to slow down the trucks, and they had to refill the tanks about half way doen the run to the mill. Like I said, weight was no a problem for these rigs.
@@V8Lenny The way it was explaned to me (over 50 years ago) is, there was an attachment around the drive line that the water was forced thru (vanes?) to slow down the speed of the truck. It created massive amounts of heat and much of the water evaporated which is why they needed to refill the tank halfway down the mountain. Huge tanks were mounted behind the cab for the water supply. There is a photo of one of these trucks on the Facebook pages for Crane Mills. I do not have permission to use the pic so will not try to provide it here. In the picture you can see how the truck cab is shifted to the left side of the vehicle and you can also see how the log bunkers are at least two feet wider than the wheels on the right side of the vehicle. I tried to find something about this method of waterbraking or hydrotarding but was unable to find anything on the web about it for anything that far back in time. Not too many logging companies had their own roads and thus not subject to load limits.
@@tomgretiredelectrician1162 ok, but they could have used engine coolant and radiator. I have seen water cooled brakes that they just poured the water over drums, thats why big water tanks. Race trucks and some cars use pressurized system to actually spray water inside drums or discs.
I really appreciate your comment about the Hall-Scott powered trucks your Dad sold parts for. I had never heard Hydro-Tarders mentioned in any of many stories or videos, I'm also an engine fanatic. Please share more of what you have experienced !
@@tomgretiredelectrician1162 It's called a hydromatic brake. Still used in drilling rigs of all sizes to slow down the drop speed of the main hoist or drawworks, saving the drum brakes. Parma's is one old company. They are going more to electromatic eddy current braking now.
My dad spent a good deal of his time in WW2 Europe driving an M25 draggin wagon tank transporter. Hall Scott 440 engine, 1091 cu in. He said it had a single barrel updraft carb with a throat about the diameter of a 3 lb coffee can. 2 gallons per mile, maybe, top speed just under 30 mph.
The M25 Dragon Wagon tank transporter was made by Pacific Car, which now makes Peterbilt and Kenworth trucks. It supplemented the Diamond T 980 tank transporter. My father had a Diamond T farm truck in the 40's and early 50's.
We are floored with this one for the standard as always is💥blown to pieces and I think you went above and beyond just like Hall Scott company did with their quality control and materials for the engines themselves! Couldn't ask for anything else from your devotion and details on this one. Bravo we salute you for a historical masterpiece and finding the samples of the engine to show us all was a great feat in itself. For this in the time of historical change as they are calling it is a masterpiece. Good morning and I hope that you have a wonderful Sunday.
@@VisioRacer you are very welcome and I hope that you have a wonderful day. From the old farm lands in Western Pennsylvania North of Pittsburgh, PA. You and your family have a great day. Hopefully it is warmer where you are, 27 and chilly here.
Your videos NEVER cease to amaze me brother. The depth to which you strive to share as much knowledge that there is out there with us, is astounding to say the least! I remember hearing about these engines as a kid growing up in the 70's, but i can't recall if i saw one at any of the shows we frequented. Always a pleasure to watch another one of your videos. Thanks for sharing more of our forgotten internal combustion history!
I love this channel! New gems every time. . Americans, eh? - “Elbert, we need to stay ahead of the competition. Make a new engine, tough and reliable as usual, it has to outlast the pyramids, and throw some cubic inches at it!” “You got it Bert, how big?” “Yes!” God bless them! We’ll probably never see the like again but this is really something. The optimism, know-how, quality, and sheer will pervaded everything made in this time. Just look at Pratt & Whitney for example. Even an M1 Garand! I drive a little 392 to capture the last of it. Makes me happy! 😁
I’ve had the opportunity to drive and maintain a 1954 Crown school bus with a 500 in.³ pancake Hall Scott. I was very impressed with the engine. Simplicity of service and durability were definitely in DNA.
Thanks for the video. It is great to get the history of engines and vehicles for the companies that have faded into obscurity. I have heard about Hall Scott but didn't really know that much about them. Very interesting.
Visio Racer is firing on all cylinders as the on-line historian of internal combustion engines. I've read of Hall-Scott in different references over the years, but never delved into them as VR has done here. I tend not to be interested in pre-WW2 truck engines because of their valve-in-block architecture, but Hall-Scott had overhead cams and hemispherical combustion chambers, putting them far ahead in design. Their heavy-duty gasoline engines carried the load for many years before the diesel was perfected. And given the EPA's apparent mission to kill the diesel engine, maybe the heavy-duty gasoline engine will come back.
With the stated intention of the WEF and the climate-change cult to destroy private vehicle ownership and IC in particular, this might be a forlorn hope. I sincerely hope I’m wrong in this observation. But it’s happening everywhere.
Probably won't happen. The big Hall Scott engines made lots of power, but it came at the cost of high fuel consumption, so the economics just isn't there, and that's something the EPA can't dictate without sending us all back to the brutality of a medieval, subsistence lifestyle. So, Hall Scott engines were very innovative for their time, but that time has come and gone. All that aside, this was a great presentation.
Hall/Scott's are a great engine. I was able to work on a few of the V-12's with my father who was a master mechanic that cut his teeth on them from the 40's in the Navy and onward. They are fuel hungry monsters.
1958 diamond T heavy rescue squad, St Paul MN,fastest fire apparatus in history of St Paul MN FD...300 HP hall-scott engine,ran 24/7 from 1958-1973... Came over the rice st bridge at sycamore St with all 6 wheels off the ground...in my 80 yrs as apparatus buff,never ever such an intimidating,screaming rig in all MN 👍💯
Nice history lesson! I don't do big trucks so I have never heard of them. As an engine nerd I look at all of them when possible. I have probably seen several but didn't know what I was looking at. You should make a video about how many manufacturers have used hemispherical combustion chambers. (Jaguar, HD Sportster iron head Shovel, etc...) to show the Chrysler Hemi addicts that Chrysler was not the 1st or only brand to make a Hemi.
My favorite non-Chrysler Hemi is the four-cylinder engine in the Citroen DS! Probably one of the slower Hemis out there, but still neat. Also those little Predator engines you can buy at Harbor Freight have Hemi heads, so there are many Hemi-powered go karts in the world. Plus, oddly enough, Chrysler themselves actually produced a version of the Ford flathead V8 with Hemi heads in South America after acquiring a brand that had been building cars with license-built flathead V8s, which were in need of an update.
@@Thinginator many hemi combustion chambered engines all over the world way back into the 20's, and the first and original hemi was built at the beginning of the 1,900's.
I own a 59 kenworth which came from the factory with a 250hp hall scott lpg. I still have a copy of the original title were its on. When i bought it, it was already changed with a cummins 855 engine from 61. Real nice you were able to get all this information.
Great episode! The first Boeing aircraft (well, Boeing-Westervelt), the B-W1, was powered by a 125 HP Hall and Scott engine (two were built). Seattle Fire used to have a few Kenworths which were H-S powered; they had a distinct, deep rumbling exhaust note at a time (ca. 1970 and on) when SFD was replacing most of its engines and ladder trucks w/ Detroit Diesel-powered KWs. The old gassers (including some Mack B-Series trucks) were faster on the hills than the newer rigs...
I had previously not known about Hall Scott, but after watching your video, I’m in love! Only the best materials and sound engineering are exactly what I aspire to in builds. Mr. Hall and Mr. Scott are the kind of men I personally admire. Thanks for providing what is for me a new and proud chapter of U.S. motor accomplishment and history. 😊
i remember talking to guys at a car shows next to mack trucks and such. we strayed off talking about unheard of brands such THIS. Hall Scott engines. This guy said in 1965 he had older truck that was a plow truck reconfigured 6 wheel drive kennworth, army drivetrain with hall Scott V12 in it. he said bastard never got stuck but every 2 or 3 hours hed have to fill up the fuel. The DOT shelled over about 500 bucks a week for a couple of these special plow trucks, (remember this was 1965!)
Thank you for the informative and well documented video, I recall H/C in marine applications amazing to think these ran on gasoline or LPG, today we only think oh high displacement engines as diesel. Great work from you. Peter Mac Donald (Penang, Malaysia ).
As a boy (I’m 71 now) my dad showed me a city bus with a Hall-Scott 6 cylinder laying on its side under the floor. A massive power plant that dwarfed anything I’d seen before. Very powerful but being a gas engine was not great on gas mileage. My dad was looking for a base vehicle to turn into a home built motor home. He said it would make the bus go pretty fast but put us in the poor house from all the fuel it used. We got something else and put a Buick V8 in it.
VisioRacer. you are literally my favorite engine spec channel on RUclips. Everyone else covers the cars history more than the engine. I love your wide range of different combustion engines, especially the outboard two strokes🤜🏻🤜🏻🤜🏻
I love engines, history not as much. But I like the basic history needed to explain the engine roots and origin. Then the engine it is what I love to talk about the most
Years ago, one of my dad’s friends stopped by our house, with an old Kenworth with a Hall Scott V-12. You could feel it coming towards the house. The family friend had said it was used for logging and could not be beat. Of course, huge fuel capacity tanks a plenty.
I think it was like in the video where the V-12 Kenworth was an experimental truck that never saw production. They did put the straight 6 in Kenworth trucks. I think those were mainly fire trucks.
I stumbled upon this by accident. I've heard of Hall-Scott engines and knew that they were used in big snowplow trucks by FWD, Oshkosh, and I think also Walter. However, somehow I always thought they were as primitive as nearly all other gasoline engines of that era. I had NO IDEA that they were so highly advanced, reliable and long-lasting. What an amazing example of top-notch design from long ago!!
Hi, Visioracer. Thank you for this video, much appreciated. I am pretty sure that Benjamin Holt of Holt manufacturing, one of the two companies which merged in 1925 to form Caterpillar, used a Hall Scott 4 cylinder engine in his 2-ton T35 tractor in the mid-1920s. Just my 0.02. You have a wonderful day. Best wishes. Deas Plant.
Outstanding. I remember thinking I was looking at a Cummins, waaaayyyy back in the day, by the exhaust, but then double taking everything else about it, was in a FWD plow truck, with a huge V plow for snow belt country roads, Great vid, consider a look in to FWD, they started in 1908, as an all wheel drive manufacturer in WI, USA.
When I was growing up in the Thousand Islands, many of the tour boats had Hall Scott Engines. Had they developed diesels they might still be in business. Most were replaced with Cummins, Caterpillar or GM-Detroit diesels in the 1960's. I should also mention that the Fairmile class motor launches used by Royal Navy used imported Hall-Scott Invaders.
James Clark some did but many used the Packard M2500 supercharged engines used in US Navy PT Boats !!! The Packards being supercharged and larger made between 1200 and 1500 HP, the Hall scotts were about 900 HP. The Packard M2500 was designed by Jesse Vincent mentioned in the video as the designer of the Liberty V12, Vincent headed the engine dept at Packard and had a hand in modifying for mass production the Merlin 1650 V12 that Packard made during the war for the Brits 27,137 of them and 18,000 for the USAAF in the P51 Mustang fighters !!
There's a modern analogue of the V12. The Cummings QST30. Up to 1,500 HP and 4,877 lbs-ft. Too bad nobody thought about dumping that on a Kenworth frame.
Interesting video, I've had books on old American trucks but they didn't go into detail about the engines, Hall Scott was mentioned a lot in the books and I was always curious about these.
Great video. I’m interested in you making a video on Continental straight sixes. The 427ohv is what my grandpa used on the farm for an irrigation pump. He barely cracked the butterfly on the carburetor to get the power he needed. These engines were in the Brockway heavy duty trucks. Please make a video.
I don’t believe I had ever seen these engines, but as a kid growing up on a farm in the mid 1950’s I recall listening to all kinds of farm engines and nothing ever sounded as sweet as those in the video. Man what a treat!!
I only saw one Hall-Scott and it was in an old Oskosk Snow Plow at the Chanute AFB training squadron. It was actually out plowing the streets after a snow on the day we avrrived for training. What an awesome sound it made with only a single exhaust stack straight up out of the hood! Dual points, dual spark plugs, dual up-draft holley carbs. A real beast!
I remember these Engines Very Well as my Dad had several of them. 1 thing I remember about these remarkable engines was Hoe They Would Backfire and Though Out About A 2 Foot Flame Up ansd Out of the Stack's (My Dad put on the second Stack) and the LOAD Backfire was so LOUD T00! Nothing compaires today like those engines. And with BIG Heavy Values it didn't seem to hurt it either...I remember Dad would Pass all the 0ther trucks unless it was another Hall-Scott powered truck this was in the 1050's when he started buying them. My brother still has Dad's favorite one of them in a barn/shop where Dad had the business back then. And it will Still G0 T00!
It would be cool if new models were still being made, even if it was a novelty or for a special commission or something. Maybe that could mean that gasoline can come back for heavier trucks or even f350 sized passenger trucks. I don't know, but it would be cool to see and especially build if I wanted to get into engines.
If I’m not mistaken, a number of H-S were butane powered, drivers had nothing but praise for that engine, that would have been in 48-51. Old Donner Summit was the testing ground. What really impressed me about the H-S was the exhaust note, mufflers were not used then
Were not HS engines in V12 form powering US PT boats in WW2. My cousin in the RAN thought the Air Sea rescue boat he was on had marinised Allisons but that is open to doubt.
Awesome story, thanks so much for sharing with us! No, I had not heard about Hall-Scott before but they really built great and massive engines from what I learned here today. I approve!!! 🙌🏽🙌🏽 Greetz from Germany
In 1966 I was a member of the College Park Volunteer Fire Department and we purchased a Peter Persch pumper truck with a six cylinder Hall-Scott engine. I had never heard of Hall-Scott, but it was a great engine. It was replaced with a two stroke Detroit Diesel many years later.
I give the kid a lot of kudos. Most people don't even remember Hall Scott's. Or The old green diamond and Red diamond motors big cubic inch gas pots. They were faster than a diesel pass anything on the road has a commercial truck. except the gas pump. I worked on a 501. In a crane. got about 4 miles a gallon I think at best. I changed the carburetor from the old Holly haystack. around and put a Carter. on it did. some tweaking with it got more power out of it and got them up to 7 mi a gallon considering the crane weighed almost 100,000 lb. And would actually do road speed. Worked on a lot of Mac gas pots over 600 cubic inches also. Most people don't remember Mack used to make big cubic inch gas pot 6 cylinders. That were over 600 cubic inches. Annabelle 3 me if you were lucky to get one of those fuel efficient maybe five. But the diesels never did much better. 1693 cat motor got like. 2 to. 4. miles a gallon depending if you had the motor pumped up to 750 horse. Anne granite it was one hell of an engine it was out of a crawler. Yes it was a bulldozer motor. That was put in a lot of highway trucks when I was a kid. The Detroit 71 series and 92 series got about 6. Depending on gear some guys got like 7. Miles a gallon. Cummins diesels it didn't matter it was 150 is all the way up to the big cam 400s they always got about 4. To 5. Miles a gallon.. depending on gears you might get a bit more. Little nostalgia for everybody. Like I said kid did a cool video I'm glad you did something on call Scott motors 😀😀😀😀😀
Excellent bit of research . Not my first viewing and still a refreshing foray into the Hall, Scott marque. 600 H.P. a wayy back then is always worth hearing recited over every year or so. After ten years I may be able to recite it myself? (vocally)
Very interested video, but I think it would have been better if the narrator had a better command of the English language. That said, I had some experience with the Hall-Scott engine when I was selling trucks in the early 1970’s. My potential customer wanted to purchase ten or twelve new trucks, and trade in a like number of used trucks. I believe that they were Canadian-made Pacific’s or Western Star’s. The challenge was that all were powered by gasoline fueled Hall-Scott engines. My company was unwilling to invest in them, so I had to find an interested wholesale buyer. Although Hall-Scott engines were well regarded by the logging industry and other off-road users, nobody seemed willing to pay top dollar, especially at a time when gasoline prices were at all-time highs.
Great video, see what you can find out on Budda engines. We had a motor grader with a 428 cubic inch flat head 6 cylinder engine. It was only 90 horsepower.
An older friend and co-worker mentioned he had worked before WWII at Century Carburetion in LA. The produced the propane/butane carburetors that Hall Scott used. These were the biggest dry gas carburetors they made. They used linkage and a barrel valve for fuel control. Jack mentioned that a fellow would show up and buy a box load of their barrel valves. The individual's name was Stu Hillborn and he was using them on his fuel injection systems for race cars.
Interesting story about Stuart Hillborn and buying the barrel valves for the hot rod industry.
Finally, my curiosity about the Hall-Scott has been satisfied. Danny Rios, the guy who taught me to drive a Cummins 335 5x4 tractor in 1972, used to brag about his Hall-Scott, butane engined Autocar that would blow all the other trucks, and even Greyhound busses away up the Grapevine back in the fifties. He said that the stack put out a two foot blue flame that would light up the night when it was pulling hard. Thank you!
My pleasure!
Thanks. Dale told me about “A-Cars” with Hall-Scott engines - and your description matches what I recall.
"No replacement for displacement" was practically their business motto.
Luke Hobbs Chief Engineer for Pratt&Whittney said exactly the same.
There's some truth to that, with the exception of how much air you can force into the cylinder, on the compression stroke.
@@toddamtmann3528 , with a decent intercooler , turbo or supercharger, four valve lean burn cylinder head, a beefed up crankshaft and connecting rod, 98 Octane Premium Petrol, quite a lot. Look at the latest lorry diesel engines from Scania ,Volvo, MAN ,and Mercedes Benz that comply with Euro 6 Emission Standards ,in order to do so, they have no alternative but use very high compression ratios.
No there is - it's called boost.
Essentially you can make the same power at half the displacement.
Why would you have a 30 liter engine when you can have a 15 liter engine that makes the same power and torque, is 1/3rd the size and uses about 1/3rd the fuel and about 200% lighter allowing greater payload?
For example, a 15 liter Cummins with 35PSI boost makes 600hp and 2000ft/lbs torque at half the cubic capacity. That means off boost the engine is only 15 liters. A 30 liter engine is always a 30 liter engine so always consumes fuel like a 30 liter engine.
Yes I know about increasing an engines power with a gear or an exhaust driven blower ,look at Roller,s Merlin 26 litres in 60 -70 Series Form 1600to 1750 ponies, the 130-140 Series burning 115\145 grade petrol 2,030 ponies. Turbo Compounding is another means of increasing a engines power without increasing its fuel consumption and internal stress. All petrol and diesel engines including the one in your car ,use the energy of the burning fuel once, with turbo compounding that wasted energy is recovered via an exhaust driven turbine coupled to the crankshaft via gears and a fluid drive . You are using the energy in the burning fuel not one but twice or three times. It works!!!! How do you think Trans Polar airline travel was made feasible in the early 1950,s ?. Not long after World War Two engineers at Curtiss Wright of Dayton Ohio modified an R-3350 Duplex Cyclone Radial, the same engine that powered Tibbet,s Boeing B-29 Superfortress 'Enola Gay' to end World War Two. A standard model R-3350 of 2,500 ponies had a new rear section fitted with three exhaust driven turbines at '12 ,4,and 8' o clock . That same engine same fuel consumption on the test stand 3,250 ponies, for example an early model Pratt&Whittney R-4360 a much bigger heavier engine 3,000 ponies, for the turbo compounded R-3350 in 1947-48 a serious pony count. That year 1947 'Truculent Turtle' a US Navy Lockheed P2V Neptune Patrol Bomber circumnavigated the world with a few exercises in flight re-fuelling , an aviation feat all down to the Turbo Compounded R-3350 Duplex Cyclones exceptional fuel consumption. @@ThePaulv12
This is the only channel on RUclips that focuses solely on the history, specs and comparisons of so many different Internal combustion engines. Very impressive. Keep up the good👏
Thank you, I appreciate that!
Just found your channel and subscribed, I absolutely loved this great job. Looking forward to many more videos.
@@caesar1295 Thank you very much!
You got to give it to them that was alot of horsepower at that time. Now they are at 600 horses but I am sure the torque is much more and the weight is much less
I am a retired truck mechanic and I have always been impressed with the early engineers and manufacturer's how smart they were to be able to figure all that stuff out they didn't have computers to tell them they had to have some Sharpe minds.
And likely why there's so much garbage being sold as high tech, everybody relying on computers to do their thinking for them.. the result is, garbage, short lived products..too bad.
@@h8troodoh Thanks for the reply Mitch you hit the nail on the head those old trucks were sure easier to work on and I think they were much more reliable. I twisted wrenches for close to 55 years and the troubles started a little over 20 years ago and they steadily got worse with more electronics and stricter emissions standards.I am 74 years old I retired a little over a year ago and I sure don't miss the hassle of working on that new stuff.
@danhuttinger5040 the thing is,too many electronics, period. Take me back to my old 250 6 banger Chevy engine.. it was a happier time in mine and likely everyone's lives.. take care my friend, enjoy retirement..
Some of us feel they were better, more simple times. I dislike computers for cars
Because there were real men & women not children that age says there adults.
Pvt non ASE gas engines so far for 12 years I learned what I know from actually doing some college family helped too.
In 1966, when I was just 15, I remember riding a mid-engine powered Crown school bus that had this really cool sound. I asked the driver what kind of engine it had underneath. He told me it was a Hall-Scott 590. We were out dropping off students in a remote area and I asked him what it would do. He floored it and that bus accelerated like a car. He backed off at 65, not wanting to be too obvious, but we both smiled. I'm not sure which impressed me more... that wonderful sound, or the raw power. Great engines. Particularly at a time when gasoline was around 30 cents a gallon.
Saw one oñce in a bus. It was mounted on it's side under the bus. I had never heard of one previously. I think it was an inline six & the time was between 1964-73. Working in a GM C shop at the time.
A lot of crown school buses had Detroit 6v53 diesels these were two stroke diesels and they were loud.
Sounds like you're describing the good old days ☺️
Diesel must have been pretty cheap back then too?
@@De19thKingJulion was told it was about 2/3 the price of gas.. couldn't give it away..
I came for Visioracer, I stayed for the big engines. I had no idea how influential Hall& Scott were in the industry.
Phrasing...
@@apancher BOOM!
Well after Hall & Scott, Daryl changed his focus and joined Oates. That failed after about twelve years when Hall stopped "going for that".
@@brianpedersen4714 NICE!!!😂
These became obsolete right before I started driving truck… if’n I was born 10 years earlier, I could have gotten my hands on one of those. Magnificent!
Finally!! Thanks!! I have worked on a number of 400's and own a 400 in a 46 Kenworth. EVERY Hall Scott motor was bench tested, dynoe'd, balanced and rebalanced. That was one of the reasons they lasted so long. The dual plug feature was a requirement for any power plant used in fire suppression. Another significant placement of the Hall Scott engines was in oil field work, where they ran off of blow off gas and natural gas. At one point, Oshkosh had a manifold set up for their Hall Scott powered US Air Force tugs that had 2 Holley 4 barrell carburetors. Nice piece. I wish I had have kept my promise to you and provided you with more information and video content. My apologies.
That’s very true about balancing.. it completely changes an engine and certainly would help it last longer. As said in the video, it wasn’t about price- that’s the key difference I guess- you cannot have the best product at a discount price.

I actually suggested doing a Hall Scott video and appreciate the excellent job you did. I've been in trucking for a long time and have been into internal combustion since I was a kid. I agree about H-S not developing a diesel engine, truly a missed opportunity. All they really needed to do was convert the existing gasser over to a bowl in crown piston design and flatten the combustion chamber in the head. The engine was so overbuilt that it would more than handle the cylinder pressures.
Right on. The accessory drive was there already. An after cooler on that blower would have been a world class diesel powerplant.
no need to flatten the combustion chamber. Just build a bigger dome in the piston crown. Having the opposed valve head and hemispherical combustion chamber would have been very efficient. And given the two spark plug ports, one could have easily been used for an injector and the other a glow plug port. I have a 400 in a 46 Kenworth and have worked on a number of Hall Scott power plants
@@3RTracing hemi is not efficient, even worse with diesel. And injector must be in center of cylinder.
@@V8Lenny not as efficient, but would have worked with minimal re tool in the plant.
From a production cost standpoint, hemi would work.
From a engineering standpoint, flattening the parts would work best.
One of you is Hall, the other is Scott lmao
@@HeyItsJonny but today when LNG engines are becoming popular, gasoline engines would be better starting point, now they are all converted from diesel, not the most efficient.
My fire department had a twelve cylinder Hall Scott powered aerial ladder truck. The sound produced by the engine was mechanical music, it was my favorite truck to drive.
What happened to it?
@@ATruckCampbell It was sold at auction. A 100ft Arial truck would be a very expensive hobby.
What make was that aerial ?
@@richardalexander2305 I believe it was a Seagrave.
In 1970 I worked on a ranch in South Central Idaho that used 2 or 3 Hall-Scott V12 engines for irrigation wells. They would idle all summer long bringing up water from 300 feet below. They had dual ignition systems and a the mechanic could change spark plugs while in operation. We got some of the best tasting water from one well and another had so much sand it wasn't drinkable.
Love to watch the wrench change those plugs while it's running...🤣🤣🤣
Probably had a compression release on it.
@@antarcticmoongiant2691 yep when you removed the plug. 😂
I worked for a school district in the mid seventys. Half of the 79 passenger school busses ( crown coach ) were powered by Hall Scott A 590 motors. Single overhead cams, the machine work was second to none. The first time I removed valve cover I was pleasantly surprised by the finish of the parts. Gorgeous comes to mind. Super reliable motors. Still miss them and the music only 590 cu inches can play. .....
I was 3 years old when we moved to a mountainous area near Los Angeles. A wildfire started on a hot Summer day and fire trucks arrived, strung up hoses and began fighting the fire. A very big pumper truck parked by the corner of our street had its hood open with the engine running the pump system. That engine fascinated me, and my dad said it was a Hall Scott. I can still remember the sound it made. That was 67 years ago.
My dad had a Hall Scott 12 in a Kenworth .i[I was his favorite truck and he rarely stopped talking about it ,Thanks for the video
It was great to hear somebody else talk about a Hall Scott engine. I only heard 1 other person talk of them my grandfather. He said only GMC came close to them.
It's nice to see Hall-Scott getting some attention here on You Tube. Along with the Buda's they are my favorite engines
Very good video.
My Dad worked on Hall Scott's in the early 1960's on truck used in the logging industry.
Had these engines.
He always talk about the HP and torque of these engines and how the outperformed early diesel engines in trucks.
Thanks for sharing.
I just subscribed to your channel.
Take care, EM.
When I was a kid our local fire department had a Kenworth tanker truck with with a six cylinder Hall Scott in it, was a great sounding engine and they used it up until the late '70s. A friend of mine had a fairly large cabin cruiser built in the late 1920's that had a pair of Hall Scott engines for power, not sure but think they were the smaller versions and they were still powering that boat into the 1980s. I was around them several times when the owner was tinkering with them and they too were great running and sounding engines. Thanks for the video!
They were probably 6 cylinder. Did they have highly polished valve covers?
My Dad talked about working on these engines in log trucks, i had seen one until now. Thank you keep up the good work.
I enjoy the way you go down the rabbit hole on our behalf. I had encountered the name Hall Scott a few times while looking in to weird old engineering, but I have never done any more research, and then you serve up a fabulous history leason. This is just perfect.
I was glad to hear you mention the cam design work Hall did for Duesenberg as it was vital in the development of high speed engines and was copied by all the racing engine builders of the time. A Duesenberg with a Hall designed cam won the French Grand Prix in 1921.
Blown away by all the stories shared here in the comments! Man the VisioRacer followers make the comments as interesting as the videos and that's no small feat! Cheers to you all and hope you all are doing well 👍
Thank you! I do my best
Very interesting ... My dad was a propane distributer back in the 1940s to 1960s and he got Crane Mills, a local logging company in Corning and Paskenta, CA to get their logging trucks to run Hall Scott s . They ran about 12 to 15 of them for years back when diesel power was very lacking. I don't know what size the engines were, but they also ran with hydro-tarders which was a method of using water for braking going down hill loaded. AND they were loaded, they ran 12 foot bunkers and who knows what weights they carried bringing a lot of virgin timber out of the coast range mountains. It was all on private roads, so no load weight restrictions. I was too young to know much about it all at the time, but my older brother (now decesed) did work for them for a while running a water truck over the logging roads on the night shift. I did forget to mention these logging trucks ran on propane.
Hydro-tarders, now maybe that is a new subject for a new posting. In the logging trucks they carried a 500 gallon tank for the water to use to slow down the trucks, and they had to refill the tanks about half way doen the run to the mill. Like I said, weight was no a problem for these rigs.
It is called watercooling. Hydrotarder is a hydraulic retarder, no need to fill tanks.
@@V8Lenny The way it was explaned to me (over 50 years ago) is, there was an attachment around the drive line that the water was forced thru (vanes?) to slow down the speed of the truck. It created massive amounts of heat and much of the water evaporated which is why they needed to refill the tank halfway down the mountain. Huge tanks were mounted behind the cab for the water supply. There is a photo of one of these trucks on the Facebook pages for Crane Mills.
I do not have permission to use the pic so will not try to provide it here. In the picture you can see how the truck cab is shifted to the left side of the vehicle and you can also see how the log bunkers are at least two feet wider than the wheels on the right side of the vehicle.
I tried to find something about this method of waterbraking or hydrotarding but was unable to find anything
on the web about it for anything that far back in time. Not too many logging companies had their own roads and thus not subject to load limits.
@@tomgretiredelectrician1162 ok, but they could have used engine coolant and radiator. I have seen water cooled brakes that they just poured the water over drums, thats why big water tanks. Race trucks and some cars use pressurized system to actually spray water inside drums or discs.
I really appreciate your comment about the Hall-Scott powered trucks your Dad sold parts for. I had never heard Hydro-Tarders mentioned in any of many stories or videos, I'm also an engine fanatic. Please share more of what you have experienced !
@@tomgretiredelectrician1162
It's called a hydromatic brake. Still used in drilling rigs of all sizes to slow down the drop speed of the main hoist or drawworks, saving the drum brakes. Parma's is one old company.
They are going more to electromatic eddy current braking now.
My dad spent a good deal of his time in WW2 Europe driving an M25 draggin wagon tank transporter. Hall Scott 440 engine, 1091 cu in. He said it had a single barrel updraft carb with a throat about the diameter of a 3 lb coffee can. 2 gallons per mile, maybe, top speed just under 30 mph.
A rare beast now a days , BUT I still want one ,or at the least to drive one
The M25 Dragon Wagon tank transporter was made by Pacific Car, which now makes Peterbilt and Kenworth trucks. It supplemented the Diamond T 980 tank transporter. My father had a Diamond T farm truck in the 40's and early 50's.
We are floored with this one for the standard as always is💥blown to pieces and I think you went above and beyond just like Hall Scott company did with their quality control and materials for the engines themselves! Couldn't ask for anything else from your devotion and details on this one. Bravo we salute you for a historical masterpiece and finding the samples of the engine to show us all was a great feat in itself. For this in the time of historical change as they are calling it is a masterpiece. Good morning and I hope that you have a wonderful Sunday.
Thank you very much, John!

Your videos NEVER cease to amaze me brother. The depth to which you strive to share as much knowledge that there is out there with us, is astounding to say the least! I remember hearing about these engines as a kid growing up in the 70's, but i can't recall if i saw one at any of the shows we frequented. Always a pleasure to watch another one of your videos. Thanks for sharing more of our forgotten internal combustion history!
Thank you!
@@VisioRacer 😉🍻
Amazing info! Thanks for sharing. I have been a mechanic for over 20 years. This was my first time hearing of the brand.
I love this channel! New gems every time. .
Americans, eh? - “Elbert, we need to stay ahead of the competition. Make a new engine, tough and reliable as usual, it has to outlast the pyramids, and throw some cubic inches at it!”
“You got it Bert, how big?”
“Yes!”
God bless them! We’ll probably never see the like again but this is really something. The optimism, know-how, quality, and sheer will pervaded everything made in this time. Just look at Pratt & Whitney for example. Even an M1 Garand!
I drive a little 392 to capture the last of it. Makes me happy! 😁
I really appreciate your work I've heard of Hall Scott engine's before but I haven't seen much detail about there engines I really appreciate this
I’ve had the opportunity to drive and maintain a 1954 Crown school bus with a 500 in.³ pancake Hall Scott. I was very impressed with the engine. Simplicity of service and durability were definitely in DNA.
Thanks for the video. It is great to get the history of engines and vehicles for the companies that have faded into obscurity. I have heard about Hall Scott but didn't really know that much about them. Very interesting.
Visio Racer is firing on all cylinders as the on-line historian of internal combustion engines. I've read of Hall-Scott in different references over the years, but never delved into them as VR has done here. I tend not to be interested in pre-WW2 truck engines because of their valve-in-block architecture, but Hall-Scott had overhead cams and hemispherical combustion chambers, putting them far ahead in design. Their heavy-duty gasoline engines carried the load for many years before the diesel was perfected. And given the EPA's apparent mission to kill the diesel engine, maybe the heavy-duty gasoline engine will come back.
With the stated intention of the WEF and the climate-change cult to destroy private vehicle ownership and IC in particular, this might be a forlorn hope. I sincerely hope I’m wrong in this observation. But it’s happening everywhere.
@@ThreenaddiesRexMegistus Cummins is already developing a gasoline engine based on their diesel.
Probably won't happen. The big Hall Scott engines made lots of power, but it came at the cost of high fuel consumption, so the economics just isn't there, and that's something the EPA can't dictate without sending us all back to the brutality of a medieval, subsistence lifestyle.
So, Hall Scott engines were very innovative for their time, but that time has come and gone. All that aside, this was a great presentation.
Hall/Scott's are a great engine. I was able to work on a few of the V-12's with my father who was a master mechanic that cut his teeth on them from the 40's in the Navy and onward. They are fuel hungry monsters.
Any engine with that kind of displacement is fuel hungry. The sound they make though... is worth every drop.
1958 diamond T heavy rescue squad, St Paul MN,fastest fire apparatus in history of St Paul MN FD...300 HP hall-scott engine,ran 24/7 from 1958-1973... Came over the rice st bridge at sycamore St with all 6 wheels off the ground...in my 80 yrs as apparatus buff,never ever such an intimidating,screaming rig in all MN 👍💯
Wow . I am 74 met a guy in the 70's told me he drove a butane tanker with a Hall Scott. It ran of the tank of butane!
Truly one of the best RUclips channels out there.
Nice history lesson! I don't do big trucks so I have never heard of them. As an engine nerd I look at all of them when possible. I have probably seen several but didn't know what I was looking at. You should make a video about how many manufacturers have used hemispherical combustion chambers. (Jaguar, HD Sportster iron head Shovel, etc...) to show the Chrysler Hemi addicts that Chrysler was not the 1st or only brand to make a Hemi.
My favorite non-Chrysler Hemi is the four-cylinder engine in the Citroen DS! Probably one of the slower Hemis out there, but still neat. Also those little Predator engines you can buy at Harbor Freight have Hemi heads, so there are many Hemi-powered go karts in the world. Plus, oddly enough, Chrysler themselves actually produced a version of the Ford flathead V8 with Hemi heads in South America after acquiring a brand that had been building cars with license-built flathead V8s, which were in need of an update.
@@Thinginator many hemi combustion chambered engines all over the world way back into the 20's, and the first and original hemi was built at the beginning of the 1,900's.
I own a 59 kenworth which came from the factory with a 250hp hall scott lpg. I still have a copy of the original title were its on. When i bought it, it was already changed with a cummins 855 engine from 61. Real nice you were able to get all this information.
Great episode! The first Boeing aircraft (well, Boeing-Westervelt), the B-W1, was powered by a 125 HP Hall and Scott engine (two were built). Seattle Fire used to have a few Kenworths which were H-S powered; they had a distinct, deep rumbling exhaust note at a time (ca. 1970 and on) when SFD was replacing most of its engines and ladder trucks w/ Detroit Diesel-powered KWs. The old gassers (including some Mack B-Series trucks) were faster on the hills than the newer rigs...
I had previously not known about Hall Scott, but after watching your video, I’m in love! Only the best materials and sound engineering are exactly what I aspire to in builds. Mr. Hall and Mr. Scott are the kind of men I personally admire. Thanks for providing what is for me a new and proud chapter of U.S. motor accomplishment and history. 😊
I am happy to read such words, thanks!
i remember talking to guys at a car shows next to mack trucks and such. we strayed off talking about unheard of brands such THIS. Hall Scott engines. This guy said in 1965 he had older truck that was a plow truck reconfigured 6 wheel drive kennworth, army drivetrain with hall Scott V12 in it. he said bastard never got stuck but every 2 or 3 hours hed have to fill up the fuel. The DOT shelled over about 500 bucks a week for a couple of these special plow trucks, (remember this was 1965!)
Mack also used them in their firetrucks, that's where I heard about them. Never knew they had this long of a history. Thanks!
Thank you for the informative and well documented video, I recall H/C in marine applications amazing to think these ran on gasoline or LPG, today we only think oh high displacement engines as diesel. Great work from you. Peter Mac Donald (Penang, Malaysia ).
They believed in no replacement for displacement... love it!🥰
As a boy (I’m 71 now) my dad showed me a city bus with a Hall-Scott 6 cylinder laying on its side under the floor. A massive power plant that dwarfed anything I’d seen before. Very powerful but being a gas engine was not great on gas mileage. My dad was looking for a base vehicle to turn into a home built motor home. He said it would make the bus go pretty fast but put us in the poor house from all the fuel it used. We got something else and put a Buick V8 in it.
Never heard of them before but I'm not surprised...America was built with people like this...quality overs sales...We need to go back to that
VisioRacer. you are literally my favorite engine spec channel on RUclips. Everyone else covers the cars history more than the engine. I love your wide range of different combustion engines, especially the outboard two strokes🤜🏻🤜🏻🤜🏻
I love engines, history not as much. But I like the basic history needed to explain the engine roots and origin. Then the engine it is what I love to talk about the most
@@VisioRacer love from sunny California🙏🏻
What a cool and interesting episode! Thanks Sam :)
Years ago, one of my dad’s friends stopped by our house, with an old Kenworth with a Hall Scott V-12. You could feel it coming towards the house. The family friend had said it was used for logging and could not be beat. Of course, huge fuel capacity tanks a plenty.
I think it was like in the video where the V-12 Kenworth was an experimental truck that never saw production. They did put the straight 6 in Kenworth trucks. I think those were mainly fire trucks.
Your research and videos are excellent, as usual.
THANK YOU SR.
I stumbled upon this by accident. I've heard of Hall-Scott engines and knew that they were used in big snowplow trucks by FWD, Oshkosh, and I think also Walter. However, somehow I always thought they were as primitive as nearly all other gasoline engines of that era. I had NO IDEA that they were so highly advanced, reliable and long-lasting. What an amazing example of top-notch design from long ago!!
Hi, Visioracer.
Thank you for this video, much appreciated.
I am pretty sure that Benjamin Holt of Holt manufacturing, one of the two companies which merged in 1925 to form Caterpillar, used a Hall Scott 4 cylinder engine in his 2-ton T35 tractor in the mid-1920s.
Just my 0.02.
You have a wonderful day. Best wishes. Deas Plant.
Learning more on every video! Never had heard about this company! Pretty cool! 👏🏻😁
Outstanding. I remember thinking I was looking at a Cummins, waaaayyyy back in the day, by the exhaust, but then double taking everything else about it, was in a FWD plow truck, with a huge V plow for snow belt country roads, Great vid, consider a look in to FWD, they started in 1908, as an all wheel drive manufacturer in WI, USA.
When I was growing up in the Thousand Islands, many of the tour boats had Hall Scott Engines. Had they developed diesels they might still be in business. Most were replaced with Cummins, Caterpillar or GM-Detroit diesels in the 1960's. I should also mention that the Fairmile class motor launches used by Royal Navy used imported Hall-Scott Invaders.
James Clark some did but many used the Packard M2500 supercharged engines used in US Navy PT Boats !!! The Packards being supercharged and larger made between 1200 and 1500 HP, the Hall scotts were about 900 HP. The Packard M2500 was designed by Jesse Vincent mentioned in the video as the designer of the Liberty V12, Vincent headed the engine dept at Packard and had a hand in modifying for mass production the Merlin 1650 V12 that Packard made during the war for the Brits 27,137 of them and 18,000 for the USAAF in the P51 Mustang fighters !!
Excellent report on this Visio!! I knew very little about this engine. Thanks!! 👍
There's a modern analogue of the V12.
The Cummings QST30. Up to 1,500 HP and 4,877 lbs-ft.
Too bad nobody thought about dumping that on a Kenworth frame.

Yeah, you mentioned these recent videos are a big commitment and it shows. Love the direction of the chanel 👍
Interesting video, I've had books on old American trucks but they didn't go into detail about the engines, Hall Scott was mentioned a lot in the books and I was always curious about these.
The magic of these Engines was. It’s torque. Torque is king on power and Horse Power and RPM carry it!!
Thank you for showing the history of engines
There was a guy who requested a video on hall and Scott I believe! This is nice to see 👍
Yes, quite often. Then I looked into the topic and had to make this video happen
Meanwhile Scania be like Hold my V8
Great video. I’m interested in you making a video on Continental straight sixes. The 427ohv is what my grandpa used on the farm for an irrigation pump. He barely cracked the butterfly on the carburetor to get the power he needed. These engines were in the Brockway heavy duty trucks. Please make a video.
Really good video, had not heard of Hall Scott/Big Scot engines.
I don’t believe I had ever seen these engines, but as a kid growing up on a farm in the mid 1950’s I recall listening to all kinds of farm engines and nothing ever sounded as sweet as those in the video. Man what a treat!!
thanks for keeping this important history of technology alive.
My pleasure
I only saw one Hall-Scott and it was in an old Oskosk Snow Plow at the Chanute AFB training squadron. It was actually out plowing the streets after a snow on the day we avrrived for training. What an awesome sound it made with only a single exhaust stack straight up out of the hood!
Dual points, dual spark plugs, dual up-draft holley carbs. A real beast!
I never heard of these engines before. They sound awesome!
I remember these Engines Very Well as my Dad had several of them. 1 thing I remember about these remarkable engines was Hoe They Would Backfire and Though Out About A 2 Foot Flame Up ansd Out of the Stack's (My Dad put on the second Stack) and the LOAD Backfire was so LOUD T00! Nothing compaires today like those engines. And with BIG Heavy Values it didn't seem to hurt it either...I remember Dad would Pass all the 0ther trucks unless it was another Hall-Scott powered truck this was in the 1050's when he started buying them. My brother still has Dad's favorite one of them in a barn/shop where Dad had the business back then. And it will Still G0 T00!
There were many great engines from that era. The engineering was quite impressive by any standard. 👍
never heard of hallscott before thanks
Top video,I had never heard of this engine before 👍👍
Our fire department usd nothing but Hall-Scott FS 1091 engines.330 raw HP and dependable too.
It would be cool if new models were still being made, even if it was a novelty or for a special commission or something. Maybe that could mean that gasoline can come back for heavier trucks or even f350 sized passenger trucks. I don't know, but it would be cool to see and especially build if I wanted to get into engines.
Nice video. I love the quote saying It can pass anything but a Fuel station. 😁
Thanks for making this video. I have never heard of Hall Scott before. Very good engine design.
Thank you for your time making this video, I have a 1948 kenworth hg825 (hg) for hall scott gasoline
Nice video, this is the first I’ve ever heard of Hall-Scott, what a great story!
That was amazing! Never knew about the v12 hall Scott engine, Al gore and his cronies would never allow great machinery like this exist today
I have heard mention of Hall-Scott, but had no idea of the history or the number of different configurations they manufactured. Thanks for this.
One of the top 5 uploaders on RUclips. Love your videos big dog keep it up.
Wow I'm speechless. I had no idea they had so much HP in the 40's.1000 is crazy.
Hall Scott is the true embodiment of “no replacement for displacement”
Thers NO substitute for cubic inches displacement !!!
If I’m not mistaken, a number of H-S were butane powered, drivers had nothing but praise for that engine, that would have been in 48-51. Old Donner Summit was the testing ground. What really impressed me about the H-S was the exhaust note, mufflers were not used then
Were not HS engines in V12 form powering US PT boats in WW2. My cousin in the RAN thought the Air Sea rescue boat he was on had marinised Allisons but that is open to doubt.
Love your videos mate, keep up the great content 👍👍
Awesome story, thanks so much for sharing with us! No, I had not heard about Hall-Scott before but they really built great and massive engines from what I learned here today. I approve!!! 🙌🏽🙌🏽

In 1966 I was a member of the College Park Volunteer Fire Department and we purchased a Peter Persch pumper truck with a six cylinder Hall-Scott engine. I had never heard of Hall-Scott, but it was a great engine. It was replaced with a two stroke Detroit Diesel many years later.
I'm glad to learn about these wonderful monsters! Thank you!
I give the kid a lot of kudos. Most people don't even remember Hall Scott's. Or The old green diamond and Red diamond motors big cubic inch gas pots.
They were faster than a diesel pass anything on the road has a commercial truck. except the gas pump. I worked on a 501. In a crane. got about 4 miles a gallon I think at best. I changed the carburetor from the old Holly haystack. around and put a Carter. on it did. some tweaking with it got more power out of it and got them up to 7 mi a gallon considering the crane weighed almost 100,000 lb. And would actually do road speed.
Worked on a lot of Mac gas pots over 600 cubic inches also. Most people don't remember Mack used to make big cubic inch gas pot 6 cylinders. That were over 600 cubic inches. Annabelle 3 me if you were lucky to get one of those fuel efficient maybe five. But the diesels never did much better. 1693 cat motor got like. 2 to. 4. miles a gallon depending if you had the motor pumped up to 750 horse. Anne granite it was one hell of an engine it was out of a crawler. Yes it was a bulldozer motor. That was put in a lot of highway trucks when I was a kid. The Detroit 71 series and 92 series got about 6. Depending on gear some guys got like 7. Miles a gallon. Cummins diesels it didn't matter it was 150 is all the way up to the big cam 400s they always got about 4. To 5. Miles a gallon.. depending on gears you might get a bit more. Little nostalgia for everybody. Like I said kid did a cool video I'm glad you did something on call Scott motors 😀😀😀😀😀
Excellent bit of research . Not my first viewing and still a refreshing foray into the Hall, Scott marque. 600 H.P. a wayy back then is always worth hearing recited over every year or so. After ten years I may be able to recite it myself? (vocally)
Very interested video, but I think it would have been better if the narrator had a better command of the English language. That said, I had some experience with the Hall-Scott engine when I was selling trucks in the early 1970’s. My potential customer wanted to purchase ten or twelve new trucks, and trade in a like number of used trucks. I believe that they were Canadian-made Pacific’s or Western Star’s. The challenge was that all were powered by gasoline fueled Hall-Scott engines. My company was unwilling to invest in them, so I had to find an interested wholesale buyer. Although Hall-Scott engines were well regarded by the logging industry and other off-road users, nobody seemed willing to pay top dollar, especially at a time when gasoline prices were at all-time highs.
I never heard of Hall Scott till this video. Thanks.
Great video, see what you can find out on Budda engines. We had a motor grader with a 428 cubic inch flat head 6 cylinder engine. It was only 90 horsepower.
Nice video Sir. Could you please tell me where the large gas v-12 engines are located ??? Would love to see these units for sure. Peace vf
