Say what you want but, these were some of the BEST engines EVER built! As for POWER, well this video proves that they have the power to TOTE the LOAD and my Uncle had one of those long nose GMC's back in the early 70's that could run 80+ m.p.h. with a 110,000 lbs.+ of logs on the trailer! I mean, those logs were soo long that by the time we pulled into the mill, all you could SMELL was PINE SAP burning from them touch the highway. 😄🤣😂💪🏾👏🏾👏🏾👏🏾👌🏾👍🏾❤💯
Definitely right on that.. 1st job was hauling concrete block. 10 wheelers ,, 1/2 the fleet were 238 Detroits, the others were 230 cummins. 1 270 Cummins on a trailer dump 1 318 Detroit on the oher. & a 318 Tri-axle. The owners brother owned he Dodge dealership in town. all our trucks were Dodge. In line to order a Big Horn tractor when Dodg stopped building trucks in the US
Rick Delair cheers man, it'd be awesome to hear a 2 stroke come back. I remember when I was a lad at school we went to Canberra from Newcastle, for a school excursion. I was in a Denning Landseer and the other bus was a MAN. I always sat in the front seat because I loved watching drivers, especially with a 6 speed spicer, I had that pattern memorised before I was 12 haha. Anyway when we were returning, I was watching the speedo climb right up to 160kph, 2 stroke 6v92T screaming, and next second the MAN wiped the floor with us. He blew by us so fast he had to be doing 200kph. This was in the early 90's before they were all limited. I still loved the Denning because of its note. I got to drive one a few years ago and the power that motor had was phenomenal.
Have you seen 35,000t iron ore trains or ships? Many older diesel locos & boat engines make music too. A few of these Detroits in boats & in a small number of small railway shunters.
It doesn't matter what vehicle you have, somebody will find a way to race it. Also, the fact that those two-stroke Detroits sound basically like muscle cars when the throttle is pinned makes them even more awesome.
yes for sure i was noticing that not a bit of smoke just loads of willing power , what great little engines pulling those heavy loads great sounds from real trucks
@Rick Delair hello there rick thank you for the information on the clarke 2 cycle engines it was great to read , its mainly four stroke engines ive worked on in my earlier career like MAN Mercedes Volvo Hino etc mainly European diesels , now i work on aircraft engines well turbines really , i will send another message to you again as im just in from a shift ,cheers
They are NOT clean burning. That’s why two strokes died. Same as gasser two strokes and Wankels. They are EFFICIENT because because every second stroke (or ever 1/3 rotation of the rotor) is a power stroke vs every 4th stroke. But they are absolute garbage for the environment. I’m not talking about the environment in the philosophical hippie granola sense. I’m talking about the inability to park a white car near or see anything grow by the train yards with the garbage spewed by SD-40s and GP9s that were once common place. Good riddance.

Both of those trucks were tuned up very nicely, running at full power with hardly any smoke. You wouldn't believe it today but those Detroit's were one of the most efficient engines when it came to turning a unit of fuel into horsepower...
These were great engines in their day, so many different applications besides trucks. My favorite is the 8V-71 na you really had to know how to shift in those days. Nice to see guys bringing these engines back to life again.
Drove over the road for 31 years,drove lots od trucks, never drove one of these. Loved the sound , met a guy pulling triples in oregon ,had Detroit with engine like these sounded fantastic said his was built up. to 600 HP to pull triples.He claimed you had to keep on the govenor to keep em going. Sometimes late at night I'll hear one on the highway,not many around,but there's no mistake what it is. MATT
NOTICE how these trucks AREN'T rolling coal when they take off. that's because they're engines are well tuned as to not waste fuel. and have good drivers behind the wheels. take notes for all you amateur diesel drivers out there
A diesel tuned to make maximum power is going to produce a certain amount of smoke, because you want to be dumping more fuel than air into the cylinder, to use every available CC of oxygen. Since vehicle engines run at various speeds and loads, it's hard to tune one to get exactly the correct amount of fuel in all situations, under all loads. An engine tuned for max efficiency is not going to be getting the most power it can; they are mutually exclusive (however, there are those who sacrifice both just so they can blow black smoke: this is just stupidity). Even in computer-controlled engines, where the fuel delivery is infinitely more adjustable than in old mechanical engines, where you had to set the fuel to whatever gave you peak delivery at power peak, even if you wasted fuel the rest of the RPM range, it is hard to eliminate the smoke, and in many cases the engine is purposely tuned to deliver more fuel than can be burned because the fuel acts as a heat sink and carries heat out of the cylinder, reducing EGTs and preventing turbo failure. I think if you go to any diesel drag race or tractor pull, you will find that most of the trucks make a great deal of smoke. This is not just because they are all idiots who don't know how to properly tune an engine, unlike you (although I doubt you _do_ know how to tune an engine, you are just repeating something you heard, or more likely, your own wishful thinking. Or you're repeating someone else's wishful thinking. Anything to prove those Neanderthal diesel guys wrong!) I'd bet that the reason they aren't making smoke here is because someone made it a condition to be allowed to compete, to tune the engines to reduce black smoke, because usually they make a lot (more than necessary, because it is a crowd pleaser). Someone decided that was too much like letting people do their own thing, and felt it needful to stick their oar in and "correct" everyone for the public benefit.
They did smoke the video scaling and compression kind of hides it.. Mechanical pump and straight pipes are going to smoke even with near perfect progressive shifting..
@@erikbreaman9124 they smoke a little but when they say rolling coal they mean really thick black smoke like an old choo choo train. i have seen new trucks with all the computer crap on them smoke a lot too and i saw one burn up also.
Ive said this before elsewhere on another comment section... I live not 2 miles from Detroit Diesel factory in Michigan. Growing up in the 70's i remember plain having the windows open on any given summer night and hearing various displacement Detroit Diesel 2 strokes just a screaming up and down Telegraph rd. Its kinda surreal to think about now. Also everyone over 40 has a memory of some MCA bus screaming around town or out in the country down some lomesome 2 lane road...and seeing many broke down on side of road...but almost Always that was due to neglect and poor maintainence. A dream would be to have a 1973 K250 Chevrolet long bed with an 8v71 and an eaton 10 speed. Maybe...someday.
theres a reason that back in the day when everybody was doing speed runs at bonneville the diesel classes were always won by leaktroits,from 3 cyl all the way up to 12 cyl.they were called leaktroits because if they arent leaking there wasnt any oil in them.kinda like old VW's and harleys.
Back in the day when Detroit came out with the 8V71 318, they were big power. Cummins big engine was the 290, still a lot of 220s and 250s on the road.
The LCF( Low Cab Forward)Dodge had to have the cab set higher on the frame, with a filler piece in place underneath the cab doors. This was so the 8V-71 could fit. This engine came with either 260,290,or318h.p. Later w/turbos they had 335 & 350h.p. ratings. If they were set up right, would run for many miles. The G.M. 2stroke has been around since the late 1930's, and was used in different applications. The truck from the movie with Emelio Esteves, was a White Western Star w/ a 12V-71.The old Canadian built Hayes WHDX 1000 logger and prime mover, had a big 16V-71 for power.
Winn Dixie? In Raleigh, NC, those dark green screamers were all over the place. Probably my favorite of every sound I had ever heard through my childhood.
Music to my ears! Reminds me of following Coast Guard 40 footers powered by a pair of 6-71s. Best on a calm, foggy morning, looking straight into those 4" pipes straight out the stern!!
"Old" diesels sound just like modern diesels, except maybe louder (less cladding, more mechanical stuff like injectors). These are built, blown 2-stroke Detroit diesels. They only sound vaguely like what they sound like in normal operation (usually they sound like someone taking their diesel up to and past the redline, because they fire twice as often as a 4-stroke diesel for the same revs). So Detroits sound different from a typical modern diesel, but it's because they are 2-stroke, not because they are old. Old 4-stroke diesels sound about the same as any other diesel. You still hear 2-stroke diesels in some locomotives and ships, but it's less noticeable there because they only run at like 500 RPM anyway. In any case, these don't sound much like stock Detroits either. Just like a Duramax running forged internals and twin-turbos pushing 1,500hp/2,000lb-ft from 7,500RPM and 50psi can be pretty misleading as regards "what a diesel engine sounds like". So a Detroit 2-stroke definitely has a distinctive sound compared to a typical diesel engine, but that sound isn't normally what you hear in this video.
4 strokes suck in trucks, outboards and snowmobiles. Even cars too I like the new 850 rotax etec turbo r skidoo and this 2 stroke Cummins mart.cummins.com/imagelibrary/data/assetfiles/0058689.pdf
Contrary to popular belief that they don't have power. The feds made them install throttle delays to reduce particulates that made them slow banging gears. But tons of power if you can stay on the throttle. They can rev like that all day every day for years.
I absolutely love all Detroit diesels even the four strokes. What killed the 2 stroke was fuel mileage and emission. The low compression caused buy the short compression cycle didn't allow for complete combustion. This produced high hydrocarbons. Because of that they could not meet modern emission standards. I have been a diesel mechanic for 30 years and watched the entire industry move over seas. Now Cummins is Chinese and detroit is Mexican. As a journeyman I would still buy a Detroit any day however I love the guys who buy Cummins because that's how I make money! :)
Both Dodges, orange one definitely a 318 Detroit, 1st truck I ever drove professionaly... Pulled 100, oo0 on a a trailer dump, no problem unless the scale was open...
Well, I had a GMC Astro with a 8V71TA, 370 HP which is the highest power rating for an 8V71 and it never pulled like either one of these. It would outrun a 400 Cummins cause the governor was set at 2800 rpm though!
Martin Coufalík but you can run them a lot harder and it helps. The harder you run a 2 stroke Detroit, the better it runs. Slam your hand in the door and let your boss cuss you out before driving. You will make it early with the load and it’ll be purring like a kitten
I worked as a mechanic in 2011 for an old man with a truck shop. He said all he ran was old Detroit’s back in the day. He said he would make his drivers mad as hell and they would get the load to the destination early by as much as 12 hours lol
@@martincoufalik9101 2 strokes got great torque for the same CID, bore and stroke and BMEP! 4 joke sounds and runs like crap and has to be band aided with all this emissions crap. These are Clark cycle uni-flow 2 strokes.
Sweet!!!! I put 40,000 miles on a Firetruck converted into a flatbed gooseneck puller with a 6-71t last year. Turns heads for looks and sound!!!! Bet it was the only 2 stroke going down I76 in all 40k miles
Terence Dalbec 3 lots of timber would weigh at least 45 tonne depending on the type of wood etc, plus the tare weight of the truck and trailers. I'm from Australia. Proof that if use change gears correctly Detroit motors go very well.
They really aren't efficient I drove trucks with a 6V53, I 6-71 8V71, 8V92TA and the best fuel mileage was 4.7 MPG almost any truck today can beat that by at least 1 MPG.
@@bertgrau9246 The 8V92T was a bit expensive to run. The TTA version was capable of getting nearly 6 mpg. The 6-71 was economical in a truck or bus so was the 6V92TA. Some people are just leadfoots that never reduce fuel intake and then winge that their thirsty.
Love them 2stroke Detroit’s but I gotta ask, what do you think their speed was when they passed the cameras? Lol literally the best Diesel engines ever made!
@@slimchancetoo What? Yes I have, a 318 in a GMC Astro. Loud, rough riding, but kinda neat. The new trucks like the Volvo VN since '98 ride so much better and are so quiet and comfortable. In fact years ago a fleet in Cullman Al. turned in the whole group of 25 VN s that they bought, 3 months after purchase, saying their drivers hated them because they rode too smoothly and were too quiet and their drivers were falling asleep at the wheel. They went back with Freightliner and Kenworth with spring suspension all the way around. You know, you can't fix stupid.
How come there are no air filters on the right side? I drove a dodge with a 318 & it had a big square FARR air fiter, & a luberfiner filter on the left side
Hey what about the small block OMC 2 strokes v8 outboaud 4L, 330hp 430 ft-lbs torque! i got a silver 8v92 also and plan on getting more 2 strokes. My 7.3 powerjoke is a POS in its 4 stroke state but converted to 2 stroke it would be something. this has been done before. here is a volkswagen 1.9 2 stroke poppet valved diesel:ruclips.net/video/qosAllch8Sg/видео.html
One 2 stroke that is scary is lightning, It is a 2 stroke beyond terawatt energy levels! But it is still a 2 stroke as leader streamer fires down and return current fires back up!

We had a 69 dodge wrecker with a detroit-road ranger trans. Was told to drive it like you just slammed the door on your finger. Trans shifted better that way.
Yah, a C900. Longhorns had much longer hoods. The orange one has the cab raised. They came that way if they had a larger V 8 engine in them so you could get the rocker covers off, as much of the engine is pushed back under the cab. On inline engines like a NH Cummins the rear head is inside the cab. You had to remove the doghouse to get at it. Try torquing a cylinder head bolt on an HH 220 that takes 600 ft lbs in one of those. All these old trucks where very noisy inside and out. Drive one of those on a long trip and when you get in your car to go home your ears are ringing for hours after. Drove one of these Dodges with a Cummins NH 250 in it. Top speed 55 mph. Pulling loads of glass from South of Detroit to points in Quebec. 80,000 lbs on spread 4 axle trailer. Grossing 130,000 lbs. it’s a long trip. The truck will tell you where the hills are even if you can’t see them. Interring thing about these trucks is the fenders folded sideways to the front. So when they where opened the headlights would be facing one another. The hood flipped up. You could stand right beside the engine. However if it was a repair over and above a service if you had a cherry picker you could remove the entire assembly in a little over half an hour. Most of that time was tagging the headlight wires. Worked on a couple that had Cummins V8 903 cid engines in them. You had to undo the front cab mounts and jack up the cab to get the rocker covers off on that combination. Cabs are very small inside, not unlike a lot of trucks in there day. Ford Louisville’s where a game changer back in the day. Good visibility for a conventional, and fairly quiet. Ford sold vast quantities of them. Now your lucky to see one rusting away in a farmers field somewhere. Where did all the Cabovers go ? Observation from an old truck driver / mechanic... “Blink and you’ll miss it.” Ps, look for more videos from Norte Dame du Nord where this was filmed. It will blow your mind. These trucks are racing up hill in case your wondering. These guys don’t full around.
They can make them more powerful and more efficient but they will never sound that good again. The war against 2 strokes sucks. A 12 92 in a big fishing boat is good as it gets
Some of the generator sets I work on are 16v92 with twin turbos. When they are loaded heavy the vibration makes your teeth itch. It's a really strange sensation
Horsepower is important ....put a man behind the wheel that knows how to drive ...priceless....hell most folks these days are taken back by the idea of a clutch
No, a Detroit spinning at 1,000RPM sounds like its doing 2,000RPM. It's pretty simple math. But "twice as fast" adds up quick, so 3,000RPM sounds like 6,000, which is pretty impressive.

If that’s an 8v71 it sounds like a gas v8 screaming at 4 to 5k rpms while it’s turning at the very most 3k rpms.
Love that sound.
Oh... my... god... I forgot those sounds. There was no shortage of those in rural Alabama in the 1980s
Winn Dixie? In Raleigh, NC, those dark green screamers were all over the place. Probably my favorite of every sound I had ever heard through my childhood.
Music to my ears! Reminds me of following Coast Guard 40 footers powered by a pair of 6-71s. Best on a calm, foggy morning, looking straight into those 4" pipes straight out the stern!!
Amazing how different those old diesels sounded.
those are 2 stroke diesels thats why
way better then the pos on the road today I drive a a pos frightshaker with a turd of a cummins in it as a dump truck it was a glider truck :(
"Old" diesels sound just like modern diesels, except maybe louder (less cladding, more mechanical stuff like injectors). These are built, blown 2-stroke Detroit diesels. They only sound vaguely like what they sound like in normal operation (usually they sound like someone taking their diesel up to and past the redline, because they fire twice as often as a 4-stroke diesel for the same revs). So Detroits sound different from a typical modern diesel, but it's because they are 2-stroke, not because they are old. Old 4-stroke diesels sound about the same as any other diesel. You still hear 2-stroke diesels in some locomotives and ships, but it's less noticeable there because they only run at like 500 RPM anyway. In any case, these don't sound much like stock Detroits either. Just like a Duramax running forged internals and twin-turbos pushing 1,500hp/2,000lb-ft from 7,500RPM and 50psi can be pretty misleading as regards "what a diesel engine sounds like".
So a Detroit 2-stroke definitely has a distinctive sound compared to a typical diesel engine, but that sound isn't normally what you hear in this video.
Thanks for that explanation!
4 strokes suck in trucks, outboards and snowmobiles. Even cars too I like the new 850 rotax etec turbo r skidoo and this 2 stroke Cummins mart.cummins.com/imagelibrary/data/assetfiles/0058689.pdf
Nice to see a drag race about driving, instead of how many dollars you can cram under the hood...
What a hell of a sound! Nothing like a 2 stroke Detroit!
there is so many comments about these 2 stroke diesels not having any power, from what I've seen looks like they do.
Emd
Contrary to popular belief that they don't have power.
The feds made them install throttle delays to reduce particulates that made them slow banging gears. But tons of power if you can stay on the throttle.
They can rev like that all day every day for years.
watch a drag race with a 4 stroke motor.
Its so amazing how they haul all that weight
Thats a scary sound to hear in the night.
CNC laser cut ports in a cat c-18 with boos for 2 stroke conversion! its been done!
i think this is the music for ears
@@sameer5634 i love the rumble of the 850 ETEC.
@@jlo13800 that's the ice ski if I'm correct right? But it sounds good
@@sameer5634 Skidoo MXZ, At idle it sounds like a 2-53.
Dang son that's what I call hauling Freight!!
Saawheet!!
Music to my ole ears!
For having only 568"under the hood, little small for a truck, those old Detroit's didn't do bad.
Best sounding big truck motor imo
My morning wood has arrived
I’m a log hauler in Alabama. I wish my 550 CAT sounded this damn good
Hahaaaa that deserves more likes 😅😅😅
@@marshallmcdowell3369 Convert you Cat to apoppet valved loop charged 2 strokes like this volkswagen 1.9 hp 2 stroke!
thats mental. love the sound of those.
I absolutely love all Detroit diesels even the four strokes. What killed the 2 stroke was fuel mileage and emission. The low compression caused buy the short compression cycle didn't allow for complete combustion. This produced high hydrocarbons. Because of that they could not meet modern emission standards. I have been a diesel mechanic for 30 years and watched the entire industry move over seas. Now Cummins is Chinese and detroit is Mexican. As a journeyman I would still buy a Detroit any day however I love the guys who buy Cummins because that's how I make money! :)
Excellent insight
Those are the sounds of real trucks.
Nothing sounds like a screaming Jimmy.
Huge version of the early Suzuki Jimny.
Both Dodges, orange one definitely a 318 Detroit, 1st truck I ever drove professionaly... Pulled 100, oo0 on a a trailer dump, no problem unless the scale was open...
Well, I had a GMC Astro with a 8V71TA, 370 HP which is the highest power rating for an 8V71 and it never pulled like either one of these. It would outrun a 400 Cummins cause the governor was set at 2800 rpm though!
I have no idea about 2stroke diesels, but looking at power output it seems like they have not that much torque as 4strokers, right?
Martin Coufalík but you can run them a lot harder and it helps. The harder you run a 2 stroke Detroit, the better it runs. Slam your hand in the door and let your boss cuss you out before driving. You will make it early with the load and it’ll be purring like a kitten
I worked as a mechanic in 2011 for an old man with a truck shop. He said all he ran was old Detroit’s back in the day. He said he would make his drivers mad as hell and they would get the load to the destination early by as much as 12 hours lol
@@martincoufalik9101 2 strokes got great torque for the same CID, bore and stroke and BMEP! 4 joke sounds and runs like crap and has to be band aided with all this emissions crap. These are Clark cycle uni-flow 2 strokes.
Pretty sure this is the most Canadian thing I've seen. Those Detroits sound amazing though!
God i love those detroits, they sound so awesome
Sweet!!!! I put 40,000 miles on a Firetruck converted into a flatbed gooseneck puller with a 6-71t last year. Turns heads for looks and sound!!!! Bet it was the only 2 stroke going down I76 in all 40k miles
The standard weight for these races are 85Ton... They're screaming by that camera hauling that.
85 ton!! Interesting thanks for the info!
wow 85 tons!!! that's 170,000 pounds!!!
Terence Dalbec 3 lots of timber would weigh at least 45 tonne depending on the type of wood etc, plus the tare weight of the truck and trailers. I'm from Australia. Proof that if use change gears correctly Detroit motors go very well.
@@andrewking9761 you betcha Aussie mate!
KARMA 2 BURNSIDE he probably meant 8.5
This is the most Canadian-American thing I've ever seen.
God damn! Very well thought through motors.
Still to this day are efficient strong and incredibly versatile.
They really aren't efficient I drove trucks with a 6V53, I 6-71 8V71, 8V92TA and the best fuel mileage was 4.7 MPG almost any truck today can beat that by at least 1 MPG.
@@bertgrau9246 The 8V92T was a bit expensive to run. The TTA version was capable of getting nearly 6 mpg. The 6-71 was economical in a truck or bus so was the 6V92TA. Some people are just leadfoots that never reduce fuel intake and then winge that their thirsty.
Listen to that Detroit sing love it
Love the sound of Detroit power
Love them 2stroke Detroit’s but I gotta ask, what do you think their speed was when they passed the cameras? Lol literally the best Diesel engines ever made!
85 ton uphill from a standstill
Dodge, the orange one!!, this is!!! Detroit Diesel power !!!
This looks just like lights to lights on Pennant Hills.
Got to love the sound of a Screaming Detroit!
love that 2stroke diesel sound
big mike check out my channel, I have one of the best sounding Detroits.
Johndeere 100
You ever sat on top of one for 15-16-18 hours while it SCREAMED ITS HEAD OFF ??????
@@slimchancetoo What? Yes I have, a 318 in a GMC Astro. Loud, rough riding, but kinda neat. The new trucks like the Volvo VN since '98 ride so much better and are so quiet and comfortable. In fact years ago a fleet in Cullman Al. turned in the whole group of 25 VN s that they bought, 3 months after purchase, saying their drivers hated them because they rode too smoothly and were too quiet and their drivers were falling asleep at the wheel. They went back with Freightliner and Kenworth with spring suspension all the way around. You know, you can't fix stupid.
Anybody have any info on the black Betty here?? I’d like to see more of her!
those Detroits sound glorious
oh what a sound, I just love that sound of a Cummins diesel ore a Detroit diesel.
And they look quite clean at the exhaust... How is it possible?
How come there are no air filters on the right side? I drove a dodge with a 318 & it had a big square FARR air fiter, & a luberfiner filter on the left side
It’s the old Dodge by a nose!
Ain't nothing like the sound of a 2 stroke Detroit Screaming Demon!
Hey what about the small block OMC 2 strokes v8 outboaud 4L, 330hp 430 ft-lbs torque! i got a silver 8v92 also and plan on getting more 2 strokes. My 7.3 powerjoke is a POS in its 4 stroke state but converted to 2 stroke it would be something. this has been done before. here is a volkswagen 1.9 2 stroke poppet valved diesel:ruclips.net/video/qosAllch8Sg/видео.html
One 2 stroke that is scary is lightning, It is a 2 stroke beyond terawatt energy levels! But it is still a 2 stroke as leader streamer fires down and return current fires back up! The streamers/leades are are made of charge cluster plasmoids and they for the piston, con rod and crankshaft of the plasma 2 stroke lightning!
We had a 69 dodge wrecker with a detroit-road ranger trans. Was told to drive it like you just slammed the door on your finger. Trans shifted better that way.
@Captain MufDyven shoo wee 12v71 that's some serious horses. Look for Mario Racicot 24v71 Freightliner
@@vabrad76 is like around 2300 hp!
I think that's what they called a Dodge Big Horn on the left
I think they were both 900's
Yah, a C900. Longhorns had much longer hoods. The orange one has the cab raised. They came that way if they had a larger V 8 engine in them so you
could get the rocker covers off, as much of the engine is pushed back under the cab. On inline engines like a NH Cummins the rear head is inside the cab.
You had to remove the doghouse to get at it. Try torquing a cylinder head bolt on an HH 220 that takes 600 ft lbs in one of those. All these old trucks where
very noisy inside and out. Drive one of those on a long trip and when you get in your car to go home your ears are ringing for hours after. Drove one of these
Dodges with a Cummins NH 250 in it. Top speed 55 mph. Pulling loads of glass from South of Detroit to points in Quebec. 80,000 lbs on spread 4 axle trailer.
Grossing 130,000 lbs. it’s a long trip. The truck will tell you where the hills are even if you can’t see them. Interring thing about these trucks is the fenders
folded sideways to the front. So when they where opened the headlights would be facing one another. The hood flipped up. You could stand right beside
the engine. However if it was a repair over and above a service if you had a cherry picker you could remove the entire assembly in a little over half an hour.
Most of that time was tagging the headlight wires. Worked on a couple that had Cummins V8 903 cid engines in them. You had to undo the front cab mounts
and jack up the cab to get the rocker covers off on that combination. Cabs are very small inside, not unlike a lot of trucks in there day. Ford Louisville’s
where a game changer back in the day. Good visibility for a conventional, and fairly quiet. Ford sold vast quantities of them. Now your lucky to see one
rusting away in a farmers field somewhere. Where did all the Cabovers go ? Observation from an old truck driver / mechanic... “Blink and you’ll miss it.”
Ps, look for more videos from Norte Dame du Nord where this was filmed. It will blow your mind. These trucks are racing up hill in case your wondering.
These guys don’t full around.
Oooh yes them screamin Jimmys I love them that scream just ignites me 🤩😍😁😁😁😁👍🏼
Well if your not impressed with this you must be dead from the neck up !! AWESOME !
They can make them more powerful and more efficient but they will never sound that good again. The war against 2 strokes sucks. A 12 92 in a big fishing boat is good as it gets
Some of the generator sets I work on are 16v92 with twin turbos. When they are loaded heavy the vibration makes your teeth itch. It's a really strange sensation
Old Screamin Demons are gettin on with the program
Well this was well worth the click for the sounds alone. It's really a shame its so short.
Nothing sounds better than trucks working hard, well maybe some 80s music! Lol
Ha the good old days
Horsepower is important ....put a man behind the wheel that knows how to drive ...priceless....hell most folks these days are taken back by the idea of a clutch
I rather watch these ol girls getting right with it than the new souped up trucks 😁👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
En Colombia los llamamos "amanza locos" muy buenos camiones!
Two Stroke Diesels are the best!!!
I would drive side by side with the trucks just to listen to the sounds of the Detroit Diesels on the freeways
Now that's real truck 'n I can't believe that music to my ears right on
What size Detroit are they running. Sounds like big 92v
8v71 aka 318 for HP
Two stroke Detroit's are doing the deal!
Screamin' Jimmy!
Motor MG Detroit super en colombia casi no lo trabajan en E.EUU les gusta .personal me gusta el sonido es propio.👍👍👍👍👍👍👍
Maximum overdrive!
And people today say Detroits got no power. If that's not power then I don't know what is!
2 POWERFULL MONSTERS!!
You guys in Quebec know how to roll!
Gotta love two stroke diesels 💪🏻
That's pretty badass!
A Detroit spinning at 1,000 RPM sounds like its doing 5,000 RPM
No, a Detroit spinning at 1,000RPM sounds like its doing 2,000RPM. It's pretty simple math. But "twice as fast" adds up quick, so 3,000RPM sounds like 6,000, which is pretty impressive.
Maximum Overdrive frenchy style.😄
Listen at that Detroit 😍
Rpm,rpm,rpm,rpm,rpm love it
♥.♥
This is similar to the race of two "Galapagos giant tortoise"
Realistically this was about a 35 second video.
