My father Jim Watson bought that car from Sherman and ran it for 5-6 more years. I can still remember squirting fuel into the stacks before he fired it up. He too set IHRA records in both E/T and MPH in Comp Eliminator. Also won the All-American Nationals in Bristol with this car in 1975. My dad had a blast in that car, and some of my favorite memories were going to the track with him when my Mom would let me. Also, the late Sonny Leonard did some machine work for dad on this engine as well. Thanks for the video, brings back good memories.
What was the car it was in back in 1970?
@@ronjacobs5667 My dad called it Sexy 6. He ran up and down the East Coast during the 6 years he owned it. From New London to Bristol to Charlotte Motor Speedway where they ran down pit road to MD and PA. I think he ran the Gatornationals one year as well.
any video of the car running?
Great story and thanks for sharing.
Thank you for sharing OP
Man that is so cool. I,m a old auto machinist from the mid 1960 to mid 1970. We built a
292 Chevy 6 where we grafted two small block heads, for a D/Dragster that set a national
Record in the day. But nothing as elaborate as that. I love your cancel, it brings so many
Great memory’s to this 77 year old racer. Thank you so much!
"Cancel" 😂
What kind of tolerances were you guys machining to back then?
That’s awesome I built 250 and 292 Chevys for racing full efi turbo lump port head custom intake, I have a set of Tom Langdon exhaust manifolds on my first motor in high school
Anyway I went home and told my stepfather about it and asked him if he'd ever seen a boss 300 and he kept telling me he's like no there's no such thing as a boss 300. He told me there was a boss 302, 351 and a boss 429. Hell we kind of argued about it cause i'd remember reading the side the car and it's saying boss 300 the guy telling me that it was a super rare motor and it was a boss 300. I took my stepfather To the shop a few days later and confirmed that it was. Mr. Massey fired it up and I remember seeing the flames coming out to 6 curved pipes and how cool it looked when he reved it up and all 6 carburetors moved in unison and I was hooked it was my absolute favorite car for the longest time and still within the top 5 to this day. It's really cool To see another one after all these years. Can't wait to see the finished product.
My grandfather is an amazingly smart man. He's forgotten more then i will ever know.
does he still live in vinton va? i sold him a 403 olds engine years ago he showed me his scrapbook full of records even when nascar had drag racing,he was putting a nascar head on a 4-cylinder pontiac block for a dragster
Your grandfather is just the type of person I would just sit with and ask a bazillion questions! What a legend. You are lucky to be a part of lineage. Aloha
He was clearly ahead of the curve at that time. I can imagine there are thoughts and designs he didn't get a chance to build that would have really blown us away.
You should be really proud of your grandfather they don't make many like him
Obviously!
As many as these engines were built, You would think some aftermarket company would come out with a cross flow head like that . I would buy one in a heart beat
ditto
I'm glad this popped up on my recommendations! This engine is a masterpiece. I would love to hear it run! Thanks for saving this piece of brilliant history!
I took delivery of one in my shop 3 days ago.
Its done so well that theres no way it was the only one.
Ive been searching and searching....and just found this video.
The owner dropped it off and said he had it in a chevrolet coupe, Im just outside of San Antonio Texas.
You really should push the owner to have this broke in and ran on a Dyno to get some numbers, then if possible once in the car, ran on a chassis dyno. We all know how much we would love to see a follow up like that, everyone like this comment to show your support!
Would love to hear this 😍 engine run 🏃♀️ 😍
i had the magazine featuring this motor , an absolute act of genius in idea and workmanship !!!!!! These are the kinds of efforts in technology that push a nation forward , the same as ideas from people like Tesla , and Edison !!! These drag racers , and engine builders paved the way for drag racing to be where it has evolved to today, people thinking outside of the box !!!!!!!!
Sherman was the service manager for Chrysler dealer . I was a Champion spark representative . I saw everything he built his little garage in Alexandra . The guy that welded up the heads did it on a naval base . Because that's where the equipment was that could do it. He also had an Opal GT with a 392 hemi in it . Then he built another class car with the Mazda rotary engine with an automatic transmission . But the 23 te bucket was the one that shocked everyone . Mechanically he was incredible . I used to watch him do leak test . What he considered bad I would consider good . I understand he moved to Roanoke Virginia that's where he's retired . Sherman was reviewed by all the people that knew him he was equal to any engine builder I knew . Around the Washington DC area within 100 miles and must be eight drag strips . Sly one was legendary and still is . I am so glad to see this being restored so people can look at it and appreciate what he did back then . Another amazing fact was sermon was humble and didn't mind talking to you if he had the time ....
@Joe Valdrighi Didn’t Mr. Sligh have a straight 8 Buick powered Altered car in the mid 60’s? Maybe I’m mixing him up with someone else? I don’t believe I ever met him, but I believe one of my high school friends knew him. Thanks, take care.
@@carlcarlamos9055 yes he did but I never sought
Joe there’s a recent interview with Sherman posted here on RUclips. It was done by my friend Tim Halstead on his Dragboss Garage Channel.
Sherman is in his eighties now but still sharp as ever. He provides some fascinating insights into his building of the Boss 300 inline six.
Just search for The DragBoss Garage and look through his videos and find Sherman’s.
Tim is dedicated to preserving anything related to the 351 Cleveland engine and its involvement in Pro Stock Drag Racing history. I race Clevelands and I think it’s an awesome source of information 🏁.
I dabbled in a few 300s when I was growing up and fell in love with the engines! I modified some for extra power but this thing is a monster!!! I thought I was setting records with big cams, big valves, big compression, and big fuel but this thing is just bigger! Awesome knowledge!
300 (4.9) Ford is a legendary powerplant. It's basically a stroker 240 but the internals rival the 2JZ as far as durability. This would be one of the top three engines ever built by Ford and it's right there with the 427 FE W code and the now amazing Coyotes.
Gosh dang!! They'll do 800hp unopened?
I've had several, great torque characteristics, comes on smoothly and solidly.
I had one that pulled so good it's still talked about 22 years later, melted the #1 piston a few times, (kept spares on good con rods weighed the same) then one day my machinist made me take 8⁰ of total advance out of the ignition timing, and a few trick things to improve cylinder head cooling, then it was a little slower, but ingot 7 years of non stop hauling in a one ton dump w heavy equipment trailer allegedly loaded to the point where I allegedly avoided agriculture check points and weigh stations, just in case, but that's probably just coincidental...pulled a one ton 4x4 454 CBB in 4wd across a parking lot letting off the clutch in second gear at off idle, then took off, before i built the dump bed, with an empty 1972 OEM wooden flatbed sans side panels. I won a quick $20 bucks, thanks to Herc, Juan, & Chevy owner Baby Joe (Lacoochie Fl.) I was, am, an old school Chevy head, hot rods, but any truck but a dodge unless it's got a Cummins and a manual trans. I had a total of 380k miles of dogging abuse on it
@@realMaverickBuckley Think more GE, not GTE, but even then you'd be way overstressing a stock internal GTE at 800 HP. I bet you could get into the 400 hp range reliably on a stock bottom end 300 I6 if you could get a decent head for one. I think you'd be hard pressed to even get 400 out of the factory heads no matter what you try. Some came with forged cranks from the factory, which I'm assuming is in the one in this video, so I'm sure you could push those a bit more. GetsumJ is probably talking more factory stock durability though. These will easily go deep into 300,000 mile territory in a heavy hauling application without anything but proper maintenance, similar to what you could expect from an old Toyota or a reliable diesel engine. Now there are lots of gas engines that will do that, but this was originally engineered in the early '60s, so legendary engine for its time.
I had a 2nd hand F150. 300 six with a 5 speed and a fresh clutch. Truck had 265k on the original engine. Third gear was the magic gear, getting on the expressway. As far as I know that drivetrain was transplanted into a 71 F100. The truck was scrapped
That is so cool! Thank you Mr Ellison for sharing this with us all! I really enjoy seeing your videos, and I'm glad you're still doing them. Don't let any nay sayers get to you. Guys like you, Uncle Tony, Derek Bieri, and Luke from thunderhead 289 are helping to keep hot rod culture alive for the next generation, thank you so much.
You did an incredible job restoring this engine. Your passion for the sport/hobby is admirable.
I wish we could hear it running in the vehicle.
I've always loved the 300 six. In my opinion the best motor ever built. Until this video series I had never heard of anyone cutting up cleveland heads,and peicing them back together to fit an online six. The man who originally engineered and built this engine in my opinion was a genius. 2 hp per cubic inch in the early 70's??? I would love to hear this thing run.
Not only 2hp/cubic inch, but using pushrods and only 12 valves! The most this engine ever had stock was around 150, which is obviously .5hp/inch haha
@@T..C..M its the weld job i looking for as cast iron head's aren't that easy to modify like that and to work at high standards and stress's ect. for 5+ year's
This is Argentina bro, take a look and enjoy!

@@richardprice5978 Dude said that it has epoxy joints, has tested it and NO leaks👍
I had several 300 , Ford and Chevy , both good motors but the standard cranks on the Ford's could not handle any abuse
Thank you for this video. In high school 1970, my dad and I built a 1966 f100, 457 gears, slicks. 300 6 cyl using vette pistons and valves, crane cam, solid lifters, 4 barrel intake and carb. Ran with the stock 350 Nova's. Never dreamed the 6 had this kind of potential. WOW !
My dad and his best friend built one of these in 1970 in Missouri. Also in a T bucket roadster for drag racing . They sawed 2 boss 302 heads and had to heat them in a oven before welding them together. they had cut up a hilborn injector setup as well. Word got out about how successful this combo was against the index and it was. Its all about the airflow of those Cleveland style cylinder heads. I also have a set of the high port exhaust cleveland iron heads that have the machined exhaust with the aluminum plate on them. They have the stud girdle Motorsports valve cover on them as well. Some great stuff from backyard engineers back in the heydays of racing!
The engine is a piece of automotive art. A testament to the inventiveness and creativity of the American spirit. Those who crudely suggest "Put an LS in it" miss the point of the engineer's art.
I've seen one in a dirt track late model, back in the mid to late 90's at Grandview speedway in Bechtelsville PA. Back then the field was split on I6 and the more expensive V8's, both ran on methanol alcohol and limited to a 600 or 700 cfm Holley. You are spot on, they were outlawed because of the inherent TQ advantages and the HP/TQ numbers sound identical to what I heard around my dad's racing buddies years ago.
And chevy s could not be found cheating no matter what was done to them we put up with the crap for years
Yup it's a hemi . Thanks Chrysler 😅
@@danielcampbell6146 Chrysler? No. A Belgian company built the first hemi powered car in 1905. Many other European automakers soon did the same.
I don't think the average person can quite
grasp/appreciate the numbers this setup generates. The ingenuity and craftsmanship alone is so clever. I would love to know/see the process of how he cut (3) Cleveland Heads and was able to weld/epoxy them together and still maintain the integrity. I watched the first video when you introduced this engine. I guess I'm gonna have to binge watch all the others.
It's stuff like this, the Frankenstein'ing of multiple parts, that absolutely fascinate me.
This content is an absolute GEM.🙏🏻👊🏻
You did a fantastic job restoring a true piece of drag racing history and explaining using the different comparisons so people could understand what it is for as little cubic inch it is , with engineering that is so remarkable remember this is 1969-70 people, 3 Cleveland heads into 1, aluminum rod roller cam fuel injected 6-cylinder making 625 horsepower and breaking track records. Great job sir 👍.
Thanks for bringing this incredible piece of history to us. The innovation in this engine is just jaw dropping. Any chance the owner will let you start and run it before you deliver it? I’m guessing I’m not the only one who would love to hear this thing run
I had only ever heard of this engine, never dreamt that I would ever see it even though it is a video. Now I have to watch the remaining videos concerning this unique feat of engineering!
I have the 240 in my 66 f100 and I’ve got to say that it is a very nice 6 cylinder and probably one of the best 6 cylinder engines I’ve had the pleasure to own. I remember seeing one of these 300s drag racing at Green Valley race way in Ft Worth when I was a teenager in the mid seventies.
In the early seventies I also owned a ‘66 F-100 with the 240 inline six and 3-speed manual transmission. I needed a work truck and since the body was in rough shape and the drivetrain had a lot of miles on it , I got a good deal.
Despite the high mileage, the 240 ran strong with a little oil consumption. I ran it very hard with the only issue being broken engine mounts which for some strange reason, were hard to find at the parts store. Otherwise an awesome truck 🏁.
You answered my questions when you stated that it's a restoration project, not a new engine experiment. Anyone who's in the "Just put an LS in it!!!!" camp needs to learn that....
That's an amazing engine. I had a 300 six in my 69 f100 pick up...never knew that engine was capable of that kind of HP. Thank you Sir for the video.
Anything can spin. Especially if the head flows and the rotating assembly can withstand the RPM. The 300 is a benchmark engine.
@@travislivengood2744 What holds back just about every inline six ever built in the US is the head. Even the Pontiac OHC had a non cross flow head. But they might have had the ports raised on the intakes. The only inline six ever built here I can think of that had a crossflow head was the Willys Tornado 230 CID that came out in the mid 60s. The head was a little strange in that each cylinder had one cam lobe. It opened both valves. Hemispherical combustion chamber too. Willys only built it for a couple of years. Then the tooling went to Argentina and was used in locally built Willys models and old tooling AMCs. One of the AMC derived models* ran at the 24 Hours of Nurburing and snagged a class win.
*64/65 American hardtop based.
@@mpetersen6 Horning made a 12 port cross flow head for Chevy in-line 6’s starting in the late 40’s. Ultimately put out 1hp/ cubic inch.
@@danwebber9494
I've seen the crossflow Chevy head on Horsepower Monster I think.
What is a crossflow head? Something to increase turbulence?
What a beautiful engine!!!! It would look great under the hood of a sports car. You are right about the time. A second is a LIFETIME in drag racing.
Yes there was a Chrysler clutch flight. Everything you stated is true to the best of my memory. While Stone Woods and Cook, Sox Martin, Al Vanderwoude, Ram Chargers were developing V8’s, Sly’s car was setting records. Sly pointed the way for short track, dirt, and at Bonneville. The sectioned head let the engine breathe so well nothing could catch it. I am in my early 70’s and remember a few of the influencers…
Seeing a diamond like this is extraordinary!!! Even if it made 400hp back then is outstanding but 600+hp thats mind blowing. Mr. Sligh is a mastermind
Just think the Honda 2.4 liter k24 stroked to 2.7 with k20 head big cams and e85 can make450 to 500 whp with no turbo or nitrous. Throw in some nitromethane and get 6 to 700hp. Years ago you could only do that with a turbo or nitrous. I would like to see what this engine could do with a better head and and cam and a computer control direct port fuel injection system so it can be accurately tuned with a o2 sensor on each exhaust header tube to get correct fuel mixture reading
I ran in Comp Eliminator in the early 80’s (351C ‘32 Bantam A/EA). Back then, Steve Ambrose ran one of those Boss headed 300 sixes and was kicking everbody’s butt.
I saw Steve Ambrose's car at Maple Grove back then and talked to him for a long time. I was amazed that you can buy one of these heads from Indy Cylinder Heads. Sure saves a lot of work 🙂
I love seeing and hearing about things like this. It's amazing what people can Frankenstein together and make work (not to mention work well).
The ingenuity is so impressive. Straight 6 cylinder engines are harmonically pure, and a proper exhaust makes sweet music.
This has me to wondering why I haven't heard of a modern version, with a CNC head, dry sump, and every other update possible.
Thanks to those sharing history via the comments too!
Awesome stuff
I just heard an interview from Sherman Sligh the original builder of the engine. It's fascinating to hear the amount of effort put in to welding those heads together. Sherman is almost 88 years old now.
we didnt weld heads they were furnace brazed
@@lewishendershott4783 lou drove the cars jerry meade built runnin this motor , the opal he took the i/gas record and held it for several years, than jerry took the motor placing it in a altered . plus lou knows a lot of the work it took to make them,

D.B. ..................he did both , ask him about 70s Corvette that ran I think E altered with 300 in it , I saw in Gville 73 or 74 . his H/MP Maverick would pull D, E,M/P corvettes half way down the track before they start back on him !!!!!!!!!!!! I was there !
@@dannycalley7777 I will ask him took a pic so I don’t forget. Thanks for the real life experience. That engine was so ahead of its time. Stay tuned. And Merry Christmas
Tim, these people also need to check out your interview with the master himself, SHERMAN SLIGH !
It really is a fascinating piece 🏁.
I had a 392 Chrysler Hemi in my 17' boat. Wicked!
My late stepdad ran a 67 Shelby 350 at Daytona and was Black flagged. 210 on the back stretch, 167,86 mph lap. 289 power.
I thought Clifford made the 300 bad, this one is a masterpiece! Thank you for preserving such a work of mechanical art.
Half-century old badass Ford Six. Set records in a T-bucket with a Clutchflite.
I think we have hit "Peak Americana" gold right here.
Deep bow to Mr. Sligh.
I would like to hear more about the clutchflite transmission.
I've asked a lot of old car/racing guys an no one has ever heard of it.
@@davidbaity3496 Long ago my Dad explained to me why a Model T would still beat most (then) modern cars across an intersection. It's planetary transmission could upshift without interrupting it's power flow. Until then I had had a negative opinion of GM Powerglide transmissions although I thought the Turbo 400 in our station wagon was nice.
Also long ago hydrodynamic torque converters for racing were unknown so some racers reverted to a convention clutch but wanted the advantage of a planetary transmission.
A MoPar Torgueflite wasn't near as good a transmission as a Turbo 400 but it is indeed what was started with originally.
Slide the torque converter off the front of an automatic and you see three sets of splines. The innermost solid one carries the actual engine torque x rpm to the gears inside.
The next (hollow) one is stationary and it is for the purpose of preventing the TQ converter's stator vanes from turning backwards when the converter is stalled (one foot on brakes other on gas). It is not used when a clutch is fitted to an automatic.
The largest (outside) hollow splined shaft drives the oil pump that enables hydraulically-powering the clutches and bands that shift ratios (not gears) in an autotrans. It splines into the outside shell of the TQ converter and turns with the engine crankshaft. On a normal clutch there is no way to drive it. So by cutting the matching splines out of a scrap converter and welding three "ears" or "arms" outwards so that matching arms or ears on the clutch pressure plate could drive them = Viola! = A clutch flite. Now you can take out the automatic shifting stuff from a racing automatic, push in the clutch, select low gear, rev it up, drop the clutch and GO.
Then without touching the clutch nudge the racing style "ratchet" shifter (won't permit moving more than one gear at a time) into second gear and BANG you got second gear. When 2nd is all wound out just repeat for 3rd gear.
Believe me this should only be done nowadays with a Turbo 400 or a beefed-up Powerglide - because the launch and shifts are BRUTAL in a race car with suspension and slicks that BITE.
YOU BETTER HAVE A CUSTOM DRIVESHAFT AND U-JOINTS AND SAFETY HOOPS AROUND THEM - because you WILL break stuff !
@@patrickshaw8595
Thank you for the information, that explained a lot
@@davidbaity3496 My pleasure to explain something I learned long ago, now half forgotten from collective memory > before I die or am unable to relate it.
PS - Quite proud I was able to type all that out on-the-fly (without composing it beforehand) before RUclips comments timed me out !
Lastly - "They" say you can't drive one of these things on the street but that's BS - you can. You just do everything like you would in a normal manual transmission, e.g. Feather the clutch for startoffs, snap it in, shift, snap it back out when the rpms are exactly right.
With a full-manual valve body and no governor you are working the oil pump many many times harder (all the pressure all the time) than normal so you need gallons of fluid and a serious oil cooler.
I didn't invent this - but you can skip driving or even having the original oil pump installed at all. You add an extra power steering pump, a (big) remote reservoir and let it do the work, It's a much bigger stronger pump.
It takes time to get RIGHT, when you get a peace of HISTORY YOU DON'T WORK FAST. I have been watching your videos for a while, and you help me a hell of a lot. Thanks you for sharing advice on all of the engines that you show and the Do and Don't. Our generation is so Lucky. Thanks friend, Larry Amerison from the swamp in north Florida.
I love those big block inline 6 Fords. Especially when they're like this one. This piece is an amazing example of craftmanship and innovation from my era. Even though I'm not even near in the same league, I won't get rid of my 300 six powered 93 F-150 simply because of that engine. Thanks for sharing this piece of history, I had to subscribe to see what else you've got on your channel.
To add one more comment addressed to the aftermarket: How about a cross-flow cylinder head in aluminum? There's renewed interest in this engine.
93 is great year for 300 inline 6. Sweeeet ford 6. My fave ford engine. Ford's most reliable torgue motor . Enjoy.
A really beautiful engine. I've watched many Ellison engined race cars perfform at Edgewater. Nice to have a video like this. Cars using engines were a treat to me because of the way they sounded and how fast they were. I currently have an "econo altered" sitting in the garage but it needs the roll cage updated. The thing that makes it unique is that it uses a former Gary Densham funny car chassis, real gold leaf lettering on the body, and titanium wheelie bars. Someday I hope to get it running again.
Your right it's a very cool engine!
I remember Edgewater. Is KilKare still open?
@@joshuagibson2520 Yes
@@joshuagibson2520 yes, paved oval and drag strip.
@@supercuda1950 yup! That's the place! Decades ago Kil Kare auto wrecking was right there close to the roundy round. It was a pretty decent junkyard back then. I got a lot of 70s Camaro parts out of that place.
I knew a few guy's who raced the 300ci6. They sound crazy, like a mix of snowmobile/indy car/sport bike combined soundtrack. One Wan n.a. the other had a twin turbo set-up. The n.a. engine was in a dragster, the other was a street driven t-bucket...from Wyoming USA 🇺🇸 🤠
I love history and engines and when they both combine its even better. Thank you for showing this piece of automotive history
So refreshing too hear mr Ellison show such reverence and respect too those that came before him and his contemporaries and the genuine excitement of the project
This engine is incredible!
The in-line six is such an efficient design. I cannot wait to hear it and find out the dyno numbers.
Yeah we campaigned several of these engines back in the 70s up threw the 90s and won lots of events both circle track and quarter mile tough engines exceptionally with a few modifications
That Engine is simply amazing!
If I had that, I'd put it up on the wall, above my fireplace to look at every day, beautiful!
I remember this engine as a kid and dreaming of building one like it....it would be a lot easier to build a replica now, because of the availability of so many really good Cleveland style aluminum heads. The modern Cleveland style heads have all of the mods they used to do built into the castings..
" it doesn't look pretty" I think it's Beautiful, Mr sligh is an amazing man
I can’t wait for the in-depth video of this engine! I remember the first video of it but didn’t know there were more! I’ll go watch the others now but I just want to say thanks to you and the owner for recognizing this engines significance and restoring it back to a period correct time capsule!
I remember reading an article in Hot Rod magazine back in the 70s, IIRC, on a Ford 300 that had a head made from two 351 Cleveland heads: one cut in half down the middle and the center two cylinder heads cut out of the other and the three pieces brazed together. It had three Braswell 500 CFM 2bbl carbs on it.
Remember that to, I recall the term "The cylinder head was furnace brazed together."
the RUclips gods have brought me together with yet another awesome engineer, and engine builder. you can make this video as long as you want. in fact, it's not long enough. dude, you're standing next to a 306 race motor with aluminum rods, roller cam, boss heads custom fitted, 1 inch raised exhaust ports, my God, I'm not a Ford guy, but that's amazing. I subbed, I liked, can't wait for some more videos. ty😎👍💯💯💯💥💥💥
I’d really love to see and hear it on the dyno as well as in the car
I’m glad this was shared. That engine is quite a feat. Very nicely done🇺🇸💪🏻
God bless you, sounds like you're as sick of the LS fan club as I am lol
Iam about sick of them also 👍
this has thousands of hours of r and d in it,its easy to get sick of something like the LS that makes killer power,every single time...
As if the LS wasn't masterminded by an NHRA enthusiast at the blueprint level. Shut up already, you're worse than any fanboy being an "anti-this/anti-that".
@@trillrifaxegrindor4411 ah yeah and as if the LS wasn't developed from the decades of R & D these guys did back then. Especially Ford. Good thing GM finally got smart and used a shit load of Ford ideas. Did you know you can put 351 Cleveland headers on an LS? Did you know you can put LS heads on a 351 Windsor. That's weird that's weird 🤣
The LS engines are great, we all know that already. They have their share of defects like any other engine. My machine shop guy said it best: "LS engines are for guys who are lazy and just wanna go fast" He then would go on to explain his opinion...there is no challenge to that engine. I personally run a well thought out 350 in a little S10. Let's just say some LS guys get embarrassed 😏
thank you for restoring this amazing piece of automotive history, i was lucky enough to work on the one built and run by the now late jerry meade from nj back in the early 70's and know of all the epoxy work you pointed out, . the head sections we used were furnace brazed back together by a place in michigan, not welded , the block we used was half filled with epoxy to help make it stronger,
What kind of epoxy did they use to do these mods?

Thanks for sharing your extraordinary restoration of this fascinating engine. You did a good job of explaining the high port conversion on the Cleveland heads. I have a pair of vintage high port iron Cleveland Pro Stock heads that were modified by Endyn Inc. back in 1982. I got them shortly after Ford SVO released their aluminum Cleveland heads and racers were selling their high port iron Cleveland heads at a fraction of the original $6000 price tag.
The intake port floors are filled using aluminum inserts and epoxy to raise the floor 9/16” from the stock location. The port width is increased by 1/16”. The result is much improved intake charge velocity for greater cylinder volumetric efficiency.
The exhaust side of the heads have about 1.500” milled off which is replaced with a section of aluminum bar stock with raised exhaust port locations. This eliminates the sharp downward turn that was incorporated into the stock ports as a poorly designed fix for clearance issues between the Mustang shock towers.
The improved exhaust flow and power increase is clearly obvious, especially at higher rpms. I plan on using these high port heads on my extensively modified Cleveland 4-bolt main short block.
Clevelands rule….always 🏁
Mr.Ellison you did a fine job with this series of vidjas. I loved every detail you have pointed out and man it is just exciting listening to your passion. I'm just a 34 yr old body technician but much respect for racing history...
Thank you for sharing this, yes it needs to be preserved. I would love to hear it run ,it would be cool to try this today with aluminum heads and dry sumps like you said .
Thanks for maintaining the history of this great backyard engineering
Id LOVE to hear it RUN!!!!!!!!!!
Gotta preheat cast iron to weld, can't imagine the difficulty in something like a cylinder head...I think it's a hell of a good looking motor. Definitely a piece of Americana.
I wonder if furnace brazing would be easier. The trouble is the seams on one of these are pretty much in the head bolt area.
Yeah, I dunno... Not something I'd be eager to try...the failure would probably be pretty dramatic though, which is in its own way rewarding. Furnace brazing would definitely make it easier.
Yes, I had seen a version of this set up back in the early to mid 70's. I was fascinated that someone could take a 300 six and adopt cleveland heads to a six cylinder eng. I am a 351 Cleveland fan and race Clevelands for about 5 years. Like U said it was not pretty, just raw horse power! The class was called altered back in my day. It blew the competition away! The event was NHRA Nationals at Martin US 131 Dragway here in MI. Thanks for the video and the history behind the build of this engine, great show! Blessings.
Wow what an amazing piece of automotive history. Purely awesome
Thank you for sharing this beautiful piece of history. Appreciate seeing a craftsman geek out over something so awesome.
Man, what a cool build. I used to have a Boss351C. Incredible motors.
This thing is sooo COOL! It must really flow a ton of air. Amazing to think that it all must have been done before 1990, even the Glidden style exhaust port plate.
I am just curious. Did Mr. Sligh come up with this creation before a Mr. Bruce Sizemore ? If you do your research, Bruce was running a 300 6 cyl. For a few years in the early ‘70’s. Then, at one point, he did exactly this combo right here. I don’t remember if his engine had injection or not. I do know for a fact he ran it in NHRA ProStock and beat several big name folks. It probably was carbureted at this point, though. I don’t know what his dyno numbers or rpm numbers were either. But they must have been quite exceptional, because, he beat several big name folks pretty badly at the time. He was running a clutch less trans also. This was in a Pinto as well, built by Don Hardy race cars. Check it out, it will be quite a interesting read. In the ‘90’s, a team was running this exact same combo except for an aluminum cylinder head with shaft rockers, etc. in a “altered” style drag car ; and they were cleaning house on a regular basis. I wish I could remember their names, because it was like 3 or 4 guys in together on the deal. I think one of the names was Argenta. That may be the wrong spelling, please forgive me.
It was done in the early 70s.
@@jimmywaters3987… Mr. Sligh is acknowledged as being the first to build an engine of this type. There were several others built afterwards including the one that Bruce Sizemore built for his Pinto which ran in the Modified Production class. I remember seeing it many times as it dominated his class.
The DragBoss RUclips channel has a video of Bruce Sizemore’s Pinto with the Boss 300 inline six defeating the late Lee Shepherds Corvette in NHRA Competition. It’s worth taking a look 🏁
Tim Halstead of The DragBoss Garage also did an interview recently of Mr. Sligh talking about his Boss 300 engine build with details about how he went about building such an amazing engine.
Anyone interested in this engine should look up the DragBoss Garage RUclips interview 👍.
I had a 1970 f100 4x4 granny 4 speed trany and a straight in and out transfer case, no high low options. Had my machine shop cut 2 holes in the intake and weld flanges to put a 2 barrel carter on each flange , they blocked the center carb mount with bolt on cover. Had a rv cam ( back in the day) I ported and polished the head and intake the best we could. Got a set of split hooked headers 3 cylinder. Came out in front of back tires in one 2 1/2 in pipe on each side. It sounded like a farm tractor but a little more pipey. It was a tourqey beast
. I could out pull any thing I came against. They always wanted to see my mighty power plant. They would cry every time. I had the truck for40 years rebuilt motor 3 times. Had over 1million miles on the truck all original motor ,trany ,drive line ,transfer, and punkins. It was my daily work truck.
That's the coolest thing I've seen in a long long time. Thanks so much for sharing. Beautiful restoration work!
Wow, just wow. Thanks for sharing this peice of history. I really hope the owner posts a video of that beast running.
Muscle car guys: WHAT?!? Import guys: cool, it's like an OHV/2v 2JZ.
That exhaust port angle is something all Indy/F1 engines use - but this engine is older than any single drivers of those current cars. Pretty cool.
Many many years ago, that little /STR showed up at our local strip and astounded everyone there. The two things I remember the most was the sound and man did that thing hook up. It was there just once but it sure left an impression on me.
Its very nice design. I think it was ahead of its time for sure. Its to bad someone couldn't take the engine and make Replica of the whole engine and make it out of today's Aluminium. Maybe like the Indy company they make heads and blocks. Anyway I'm just throwing Ideas out there it probably won't ever happen. Its just a good day dream. I want to thank you for showing off such a masterpiece. Thanks Ray
Awesome piece of History invented by passionate engineer. Sad to see that passion is disappearing for inventing like this. If it doesn't say no in the rulebook it's okay to try. Outstanding
An article from the drive brought me here. So glad it. Great work
Well for starters... if anyone is going to watch this video then they are a car person in general and more than likely a engine person as well so I really don't know if you could make to long a video. 2nd ... I am a Chevy guy at heart but I am really into engines and that right there is an amazing piece! I am going to check out the other video on it too.
I always wondered why someone would complain about the length of a video, when they can so easily skip around if they want... I mean, isn't that a little funny, thinking "There's too much information in this video, because I don't have the patience, nor time to watch it.", yet you can just skip to whatever part you want, anytime.
Excellent video, by the way. My brother is an engine builder, and Fords especially, so I've an appreciation for this.
that much HP from such a low CI? That is insane! you typically get that power from 540CI V8 Long block chevy!!! That is mind blowing!
I recently bought a badly wrecked 70 f-100 to get the bed and some other parts for my ‘71 sport custom long bed. Gave $800. Seems like a lot but the bed itself is with that. Anyway. It has a jasper 300 six in it with 500 miles on it. Hopefully when o peel the twisted front end off, I’ll reveal an unhurt engine. Been wanting to build one since I was a teenager. These videos have boosted my motivation. Most ppl underestimate these engines
Incredible engine. Just gorgeous to boot. This beast must be spinning to around 8,000 rpm to make that power. Just incredible.
It would have been amazing if some company made a 3D scan of this head and made the proper changes and parts so that these engine parts combination were something available to the general public.
That would've happened had chevy been stamped on the valve cover.
hell YA
My thoughts exactly...
i wonder if one of the aussie barra heads would fit
@@SpiderMan-rt4cd, the Barra engine is OHC. The 300 is OHV.
WOW, I mean WOW! That is a great looking engine. Not too many people want to build “A BETTER IDEA FROM FORD”. I’d like to have that under the hood of my 67 Mustang in place of the 200 in it. Bet it makes wicked torque and some h.p.. that looks like the cover of Hot Rod mag back in the spring of 1960, only better. See, I told my G.M. Wife I don’t suffer from that terrible G.M. Disease called LS, it’s worse than COVID. Thanks for posting and sharing, Keep the Ford faith.
love this motor and all the old school engineering behind it, love to get someone to do a billet head for one and go even further with it. we'll done ,awesome engine
Old catalog/magazine photographer's trick for photographing chrome. Make a dilute mixture of water and milk (you'll have to experiment with the ratio) and spritz it on the chrome piece, let it flow out and dry. It will dull it enough to prevent the glare but still look chrome.
I saw one of these in some type of altered class back in the 80s at IRP. I spotted the Cleveland head right off the bat in the pits. I think it ran like 9.40s. I also saw a 71 to 73 big body mustang with a 351c that had the block filled with concrete. He blew up and I saw the concrete.
I remember this as a kid. Didn't realize this combo resurfaced.
And yes, a Clutchflite is clutch equipped Torqueflite. They did clutch equipped Turbo 400s, and possibly Glides too.
Who did them
@@xmo552 you did it yourself, i have an old hotrod magazine that goes over the procedure step by step
@X Mo I believe it was Art Carr who did the Clutchflites.
@@xmo552 B&M and Art Carr primarily
This configuration NEEDS to be available on JEGS
Man. I'd love to see this thing tear it up. I have nothing but love for the straight 6 engines because they're just different.
I am a rtired truck driver and love anything with an engine and whees. In my younger days my dad and I use to build engines for mainly the neighbiors as somthing to do in our spare time. As I said I am a professional truck driver , not a professional mechanic, but, I love working on cars but dont so much of it any more. This isd really about the videos you had about the bad lifters. But before I get started, I want to say I thinkk you are a real professional in every way. I love youy videos about the 310 ci Ford with 625 hp as I am basically a Ford guy but love anything with wheels. The other man you were talking about was also correct too. I thonk bot of you are right aboput the lifters. now, for my opinion ; Neither one of you told what brand or kind of oil you used. It may be a lifter problem and an oil problem. With all the new semi senthetic and full synthetis oils on the market to day , I think a lot of the problewm lies with the oil. The few engines we built when I was young we had no problems with. I have seen engines torn down with the old Quaker State and Penzzoil in them and you couldnt hardly tell where the rokcers were, I will be 70 this year nad since my 20.s I have used nothing but Castrol. Today you cant find regular just semi synthetic, but still use castrol with the exception of my 2015 MUstang and i take it to the dealership for changes and use everything recommended by Ford. They put an additive in the oil because it has the 435 hp coyote engine but I dont hot dog it much so I have them add the additive to help clean it out bercause I dont drive aggresively. But I think that in my opinion, the oil may have a mlot to do with the lifter problem, Thank you keep upthe good work I love your videos!
You could do a two hour video on this engine
From teardown to dyno and it would get a lot of attention man
Beautiful piece and thank you for not trying to modify it beyond necessary repairs
Anybody that would suggest putting an LS engine in the place of that 300 needs to go direct traffic out on the highway in the middle of summer with a red snow cone awesome awesome to see you putting this thing back together we need more people to build engines like this make it fun again seems like everybody's got a thousand horsepower mustang or Camaro which is awesome but there's something just super cool about building these olds inline sixes I love it
No kidding 625 hp wow 2 hp per cui in 1970 thats very impressive i do know the 300 were bullit proof to begin with when you think you've seen it all great vid
Cool. Ford 300 6 is my faverate ford 6 forsure. Great torque and this must pull hard with this work done on it. Thanks for sharing. My dad would love this because he was a big fan and 300 was his faverate engine as well. Beautiful
The 300 6....literally my favorite engine ford has ever made.
Hearing this, makes me reconsider a 4bt swap in my f150…
Badass engine and badass video. Thank you!
I'm late to the party, but my good friend and I saw the car at Bristol in the 80s. It was so cool and had a sound all its own!
I remember the clutch flight trans. You can imagine the advantage at the starting line...
As for the epoxy work, that is old school, probably JB weld. Bob Gliddon did a bunch of work on his heads and finished it off with JB. I have seen small holes in engine blocks repaired (temporarily) with good old Justice brothers (JB) weld.
I have used it to repair curb rash on alloy wheels (or use liquid steel) sand smooth, must use aluminum primer and then epoxy paint -- low buck but it works!
We used PC-7
Wonder if Smokey Yunick knew about these motors? Know he was a Chevy man, but stuff like this is right up his alley. What a great piece of working Art.
Somebody needs to be casting those cylinder heads!
And an intake for it.
Ellisons Machine Shop Cool stuff man. I was wondering if you will be putting a dyno video or at least a video of it running? I'm guessing everyone here would love both.
Most people do not know what a 300 will do just by letting it breathe. The old saying was that it would (in a truck) do 80 off of a cliff. Change the cam and intake (and subsequently carb), and go to a late model exhaust manifold and you would be very surprised what it would do in that truck.
Nice to see the owners leaving it as engineered back in the day.
My pawpaw had a dirt car called the puddle jumper back in the 60s and 70s. It was a chevyII they took 327 heads and cranks, cut them apart, bored and sleeved the original Inline 6 engine and put the welded together crank and head in the car along with custom rods. Those old guys knew how to get things out together out of nothing back then.
