What I find impressive is they've made a crossflow head design without the drawbacks and engineering failures of the 4.1L Ford crossflow six. The 250/300ci family was a far more robust and modifiable series of engines, and if you seek among Australian forums, there is much quality Intel on getting these sixes to haul arse.
Dude, make patterns off that head if you can, and have a foundry cast some from aluminum! There's gotta be a thousand guys that would buy a modified 351C 4V head for a 300-6!!
Hi Ken. That distributor cap and when you said 310 cubic inch was a dead give away for me that it was a 300 cubic inch Ford truck engine but that head had my head spinning WOW! Keep the videos coming I love them!!!
Great to see this legend! I've been building up a small ford six for years now, shoe string budget, finally starting to get somewhere. Crazy solid, underrated machines. It takes a real understanding and interest in why they're so great to be willing to take the long and often expensive road to building one for performance. To me, its all about the small victories and lessons learned along the way. Cheers all, keep hotrodding alive!!
300 6 cyl with a 4 speed manual is an amazing work engine. You could haul stuff around all day on 5 bucks worth of gas. I even ran mine once on a mix of diesel and cooking gas and used chain saw chain oil for lubricant and she still got us home... Also with a an 11 foot water logged old camper on the back of a half ton , in first gear on pavement it would do wheelies!!! I sure miss that old ugly brown truck....
Those stait 6s , have always had a boat load of low end torque , I've known guys to build a mustang that would pull the front wheels off the ground in 3rd gear , with a three speed top loader between lights one block away from the 1st , and out run big blocks in that short space , every time !
I’ve driven/owned a couple 300 Ford Straight Sixes. One I it in an old Econoline Van, I installed with the help a couple friends. Hooked to a C6, with a 9” rear end with 4:10 posi. All this in an older straight axle 64 van! That was quick and could tow a mountain. But even with just a big old one barrel carb, was a gas hog. The second came in a 95 F150,4x4, 5 speed reg cab short bed, that was an amazing work truck. That one time off roading had been flooded in water up to the carb! I removed the top of the air cleaner and the truck started back up an drove in low range up out of the river crossing. But even with just 3:08 gears with the help of the 5 speed was also a gas hog.
My first vehicle was my dad's old Ford rack body truck, had colum shifter " 3 in the tree" with the strait 6 motor, had great low end torque, I have to get my hands on another now and give it a go!

My guess is a 300 Canadian Ford 6. I had a 250 crossflow in my Australian falcon Ute. Similar origins. Great motors. The base for the modern "Barra" Aussie 4.0 six.

I've seen 6 cylinder Ford race engines used in Formula Ford open wheelers with straightened ports that shoots for the sky, but chopping up 4V Clevo heads to make a single inline head is utterly insane ! U are right - I have seen some unique builds but never anything like this ! Thank you for sharing this and enlightening us !
As much of experience in building engines as you have Mr. Ellison! If you didn't point out everything on this piece of Art? Incredible! Thank you for sharing this beautiful engine.
Very well done mate, love your enthusiasm. As my dear late dad used to say " now that's bloody hot rodding ". As a little kid in the 70's i remember HEAPS of wild altereds and my uncles slingshot dad and him built in 68. Here in Australia the flathead or y block was all most young people could afford until the windsors and chevys reached the wrecking yards. There were some mad sixes around. And even wilder v8 killers now with the tubo charged Falcons. Thank you from Australia.
Wow what a engine please share the complete tear down an the rebuild an hopefully the start up an maybe a run on the dyno too. Keep it up love the content.
Wow!!! This is amazing!!! A completely custom fabricated head from several 351 Cleveland / Boss-302 engine head segments that have been cut, welded , sealed and structurally strengthened to match the 300 CID Ford bottom-end.... That is a great engine to begin with!!! Very cool!!! My guess is this was developed by a small group of Ford engineers to see what the potential was, of the Ford 300 inline 6 engine... Similar to what the Chrysler engineers (Ram-Chargers) did to reach the maximum potential of their early Hemi's back in the mid to late 50's with Naturally Aspirated modifications that really brought those machines to LIFE!!! This reminds me of that type of experimentation, ingenuity and power exploration.... The early days of drag racing were amazing!!!
NAH! Back in the 1970's I saw a Jr. rail dragster that had a 300/6 in it, but it used cut up aluminum heads from an aftermarket 302 or 351 Boss V8. It easily ran low 10's.
Way back in the day , I disassembled a few Ford six cylinder engines , I did recognize the block , but also could tell it was highly modified. Simply incredible some of the stuff they did to this engine. I have never seen anything built quite like this.
When you said built back in the 80s, that made me feel old, lol. Badass, a work of love, the guy that built this probably bleeds Ford blue. Absolutely awesome. Congrats on your successful business, I'm a Mason of 43 years and still working. Nice video. 👍👍🏁🏁
Thank you for sharing this, can't wait to see more of it. I figured it out right as you explained it. I've done alot of work with those heads very cool to see how it was legoed together to make something very impressive.

I'd really enjoy hearing your story. I started out with the very basics when I was twelve. I learned engines by hanging around my older brother and his small block powered 65 Impala and then, especially, his 70SS Camaro. I was modifying Briggs and Stratton engines long before major manufacturers were. I had my dad take a camshaft to work so one of his co-workers could lay a thick bead of weld on both lobes. I spent MANY HOURS hand filing , checking and rechecking the lift and profile of the lobes and already had a pretty firm grasp on how a longer duration and how lobe separation angles would effect performance. I built an intake from an aluminum tube from a fishing net that ran two carbs. I HAD to use epoxy to make the set-up work. Again.....I was twelve. I heavily ported the engines's intake and exhaust ports and using a flat file, shaved the head as far as could be done. The old lawn tractor frame that I had the Briggs engine in would burn rubber all the way across pop's garage floor and when it would hook up on asphalt would flip the tractor over if I didn't put my feet down. Thanks for sharing this video and allowing me to reminisce and share a great part of my very early years of engineering and learning high performance engines. I'm 58 now and will never let that passion die. 💪😊👍 EDIT: BTW i have a 96 F150 4x4 with THAT engine in it 😆 Do you think I'm gonna leave it stock ? Not a chance brother 👍👍
Try doing it with ls heads instead of cleavland heads. The bore spacing would make it easier and there more more parts readily available. That is if you plan on doing something like this. Ive also been playing with flathead brigs scince i was 10, im now 15, but im trying to sqve up for a cheap harbor freight welder to weld the lobes of the cam. Its a briggs 3.5 hp with a Raptor Racing carb off of a 5 hp. Its also an industrial block, so its sleeved.
I wasn’t lucky enough to have anyone to help me with my cam on my cart. I made a jig for my cam to lie in and with an old electric sander, I took.060 off of the round part of the lobe. Then, I took a little off of the lobe to round the ramps. Took the valves and put them in an blown up engine and lapped the valves until they were short enough to seat on the new cam. With that, I got my first protest.
man its refreshing meeting another motor guy. were a dying breed you and i. i wish you luck on your endeavors and if youd ever like to talk to another motor guy it could be fun. i have alot of strange builds ive done/next on the lists.
Bob was a genius. He did things that nobody never even thought of. Gay Wiliams (his carb man) also did things nobody was doing. He still is today. DragBoss on you tube has his own channel and has things from Bob. That is all he does today. You would have to be above the rest to win as many championships that he did. Billy is running in his dad's foot steps. Ronnie.
The plate on the exhaust reminded me of how old school racers cured restrictive exhaust ports on Cleveland heads. I assumed it was just a mod applied to the factory 6 head, the ingenuity involved to build this is mind boggling🤯
Heard of this. Also heard of this being done with 354 hemi heads.. There's also a dude currently building a 300 based stroker with a custom LS head. Can't wait to see it run.
I don’t know if it was the same car but around 1970/71 at a small 1/4 track in PA (Numidia) there was an Altered car from NJ that had this engine combination racing. I don’t remember the guys name. Fast as hell but very weird sounding with the six cylinders. I’m pretty sure it would not have had the cut/raised exhaust ports because I seem to remember that was a Pro Stock modification. I have been looking on/off for info on this engine combination for years. There was a magazine article about this combination during that era and I believe it was called a Boss Six. Thank you so much for providing the videos and it great to know that at least one original example survived.
Joe Williamson ran one for years in the Gas classes (F Gas if I remember correctly); Back when the NHRA encouraged innovation in the Sportsman classes.
Mr. Ellison I remember as a young kid (9 or 10) mabey my father explaining verbally and in action in our shop all of the power gaining attributes and modifications done to this ford engine as well as some things that aren't done to it as well, just saying I appreciate the video! By the way my 2 hero's and role models in my life are 1st my father second Bob glidden.
I never would have guessed that. Great design. You should do something different and weld your fav heads together and post it all. I would def watch with amazement. Love engines too.
Just beautiful!!!! Knew a guy who ran one of these in a 70s Maverick....ridiculously quick car....sounded weird, too. He never told anybody what he had done to.....or why he did it! Just another unknown genius, I guess. Only guy I knew who ever beat him heads up was running a suspiciously stock looking 383 GTX that ran low thirteens...and he only beat him by a fender length.... Thanks!!!!!
You are absolutely right and I love watching you talk about it. Thanks for your time and effort, I will like and share this with everyone I know. Great day and enjoy your evening, stay warm.
My father-in-law (RIP) was a heck of a dirt track racer in the 60's and 70's. He was a ford mechanic. And he biult and drove for the Dealership he worked for. He won championship running a ford inline6 against all the V8's. He said he could get amazing RPM and torque from his 240ci motor. He used as much 289HO specs for reference as he could for valves and cam specs. He would biuld his own manifolds and exhausts to suit his cam combination and gearing. That old dude was a true racer ! Still drove fast in his Mustang until his final days. I wish I could share this video with him. He would get a kick out of this creation.
Awesome & really cool engine! But it's funny how you were trying to hold back on identifying the motor until later in the video, even though ya forgot about the FORD sticker right there on the front of the engine, lol. I'm assuming that's the water inlet, what is suppose to be the thermostat or water pump housing ..........( just above the harmonic balancer. ) Looking forward to seeing this engine taken apart for closer inspection & descriptions!
Ford 300 has a 4.48 bore spacing, 351 Cleveland has a 4.38 bore spacing. It is far enough off that if you welded two heads together you would probably have a problem with intake valve to cylinder wall clearance problems. Very cool engine with a huge amount of work done to it.
It can be done with two heads if you center them on two cylinders. Cut one head in half and use each half on the outer two cylinders. Cut the middle section out but let it be a little longer to make up the difference. The valves will be a little bit offset but not too much.
Cool thanks for sharing never seen one bin the car repair business for over 45 years with my Brothers started with are dad of course we do drag racing cerntly do automatic trans like you we keep it real thanks
I'm sure you know by now but the Builder/designer of this engine is Sherman Sligh. Fantastic man. There have been several engines like this built over the years. The team of Steve Ambrose and Bob Huetman and Ray Argenta as well as Canadian Ralph Hope ran these until Alan Johnson of Top Fuel fame designed and made a Billet head for them.
@recrdholdr I remember seeing a front engine dragster with this engine combo in it, at St. Thomas dragway a long time ago. I don't recall meeting the car owner, just thinking it was a cool idea
We are enjoying it and thank you again for your time and work! My 85 year old Dad said that he remembers it and the poor guy had his car tore up by the NHRA guys looking for how he tried to cheat and tuned it in after the police could be it find any thing. NHRA GUYS ARE STUMPED.
Love that inline Ford, I've been building an racing inlines for 50 years. Started out in 72 on the great Pontiac overhead cam 6. Also did alot of the slant 6s. In the 80s moved onto Toyotas inline, then jeeps. Today we're pushing the 4.0 jeep motor to 1000 h.p.
@@jackdale9831 never heard of it, but there was a dohc 389 in 63that was done at Pontiac along with a sohc 421 and another that came later. Cannot remember what size though. None of the engines made it to production cars unfortunately.
I graduated in ‘76. I remember reading about a GM six cylinder having similar surgery. Cutting up 305 or 327 or 350 heads to mount on the block. They were welded together, two combination chambers added to four. This also put intake and exhaust on opposite sides. A few guys at school had hefty six cylinder novas and mustangs. It was the cutting edge, I guess. Thanks for throw back.
I remember reading about this in "Car Craft" magazine back when I was in high school and seeing it run at the local drag strip in a Maverick named "Preparation H" that was reported to run an engine just like this, 300 inch Ford block with sliced and diced 351 Cleveland heads. It was fast as any V8 powered car in its class and put a lot of V8 cars on the trailer scratching their heads and it had a unique exhaust note of a 6 with the resonances of a V8. I've followed you for a long time and I'm glad your the one who got the job of brining it back to life because of the passion you have for your industry.
I a H Modified Production Maverick at Englishtown many years ago, probably 1975 or 76. The owner/driver was Nate Cohen AKA Nazy Crate. I talked to him at length about the engine because I really liked the six bangers and straight 8 dragster like Pete Shadingers straight 8 rail. Nate said "you're looking at a $2000 head. I believe his cylinder head was made from aluminum Cleveland heads. The one in this video was made from cast iron. It took 12 hours of welding with the head heated to 1500 degrees. There is a whole RUclips video on it.
I had a 1968 Ford 1-1/2 ton truck with a 300 6 banger mated to a 4 speed. That is a workhorse combination. It actually sheared off all the rivets holding the ring gear to the carrier.
Great engine! IMO, the Ford 300 I6 was the best motor ever made for the working man! Extremely reliable, easy to work on, and good for 400,000 miles before a rebuild. I have a 1979 Ford F100 with the 300 that I rebuilt last year. The motor had 412,000 miles on it. I have two more blocks in my garage if anything happens to that one. America was built with the I6 motor!
That is a beautiful piece of machinery and it surprised me I was right at 300 Ford 6 cylinder I was surprised I got that part right but 600 plus horse power oh my God that is a horsepower monster and I love your videos I learned so much and I'm in the process of doing 360 Chrysler motor for a Dodge pickup
That is so awesome I have never seen anything like that, to take something cut it up and make it work in your mind and put together with your hands epic. Bob Glidden is my favorite prostock driver. Me personally would love to here how you started your life as a engine builder then a business owner. Because my big dream was to own a garage. I remember when I was young sneaking out of my back yard and go to the Mobil gas station and watch the guys work on cars, then I was old enough to get a job there then the bug hit me and and I just knew that's all I wanted to do. Then the side of town I lived in everything started to close life moved in I went truck driving, and now at 58 I still love working on my cars and living my dream life though others that got there dream. To me it just doesn't matter what brand it is or what part of the car it is motor,trans,different it's still a work of art and I still get to get my hands on it.
You said 310ci. And as soon as I seen the distributor placement and pushrod cover I was thinking 300. But the crossflow head had me doubting. That's a wild engine. Cool stuff for sure. I want to hear it.
Batten Heads, of Romulus, Michigan, built heads like that for Bruce Sizemore's Pinto way back when. They also did head work for AJ Foyt, and many other strong running Indy teams. Nice piece.
Pretty neat. Speaking on rare engines that produce this kind of horsepower. Have you ever seen a motor built for quarter midget? To race the chillibowl? Literally a v8 cut in half? Would be neat to see you break down one of those engines in a future video.
@@1philliph Chevrolet midget motors are old nascar v8 W/166 CI @ 350hp 4000-9000 rpm range. Toyota is now the leader though i heard. Over 400hp fron rumors i heard but i haven't seen #'s A few years back some guys from new Zealand brought their v8 version CNC engine that matched 166ci rules. They let them race and then banned it however.
a roommate of mine in 1979 had an old econoline van w/ a 300 cubic inch straight 6. when I was helping him do valve adjustments and tune up, I had no idea anyone could make a racer out of one.
Freekn awesome. In line 6s are the best motor to start with. The big issue is the under square poke and stroke. You need some pretty tough rods and crank
im not very good with engines, but I know enough to appreciate this engine. You can see how much time and thought went into customizing it and getting it to put out some crazy power.
The bottom end looked familiar but the head really threw me off. Then you explained it. Good luck and be careful with it those segmented heads already make me nervous.
Saw something very similar at the 79 Winstons. I was only a teenager at the time, but I know it was 300 Ford motor with a cut up head. It was in an altered car and was extremely loud. Won his class.
You mentioned Bob Glidden did he run this? Curious about the cam specs. Any idea who did the cam? Has to be a custom grind. I'm mostly a Chevy guy, but I'm still interested in all of them. Like the old school stuff the most. Great channel.
I thought it looked like a 300 inch ford but that being said, I wouldnt be able to identify a similar Chevy or Mopar. Ive just been around and worked on some of these over the years. Whoever did this had some serious time in it and you are correct, he is an artist
There was one here in San Antonio at T&P Automoive back in the '80. I do not remember all the details of where it came from. We had a 302 with Australian Cleveland heads used in a Oval track car.
I always knew about the power of a straight 6 engine...i had a old 74 ford Van from Telephone Co. and it run like a scaled Dogs...and everybody thought that it was a 8 cylinder...i loved that Van...with that engine...the engine I had was unicorn because of the way it preformed...i could start it up and it would idle the same in any weather without touching the accelerator at all...and could take off even if it was 30 below...it never missed or shut off or anything...its was ready too go at anytime...it run so smooth...i was a unbelievable engine...
I picked the Clevo head but was thinking Jag block. I’m in Aussieland so, as any self-respecting Ford guy of a certain age would, I’ve had a couple of Falcons with Clevos-best sounding V8 I’ve ever had-compared to Windsors and Coyotes since (incl S/C one). My couple of Clevos were generally stock other than one I built, which didn’t go as well as it should have due to massive ports with small cams and carb. Just a silly mismatch due to being young and stupid-but too poor to feed it the juice it needed. I went waaay too small in the carby and cam to let it breathe the way the heads and bottom end could.
Hey Ken, Love the video! I knew what it was as soon as you pulled the cover off. This is the same engine build as the one Bruce Sizemore had in his pinto, I think in 1975 and won the prostock championship with it!! I can not remember who he was staged against in the final round, but I do remember it being a white GM car. It is hard to mistake the design of the 300 and then, when you see the Cleveland ports and canted valves up top it is a dead give away!! I love the way they did the front timing cover to drive the enderle pump for the injection system. I know, I am about 9 months late on this post but you said to leave a comment if we recognized what it is. LOL I am a FORD guy and also an engine builder. I love those Cleveland heads. I have got to get caught up on your videos, I have never seen one of these heads off the block. I am also curious about the cam choice, and the way they lightened the crankshaft as well. Thank you for you time. Earl

I was modifying Briggs and Stratton engines long before major manufacturers were. I had my dad take a camshaft to work so one of his co-workers could lay a thick bead of weld on both lobes. I spent MANY HOURS hand filing , checking and rechecking the lift and profile of the lobes and already had a pretty firm grasp on how a longer duration and how lobe separation angles would effect performance. I built an intake from an aluminum tube from a fishing net that ran two carbs.
I HAD to use epoxy to make the set-up work.
Again.....I was twelve. I heavily ported the engines's intake and exhaust ports and using a flat file, shaved the head as far as could be done. The old lawn tractor frame that I had the Briggs engine in would burn rubber all the way across pop's garage floor and when it would hook up on asphalt would flip the tractor over if I didn't put my feet down.
Thanks for sharing this video and allowing me to reminisce and share a great part of my very early years of engineering and learning high performance engines.
I'm 58 now and will never let that passion die. 💪😊👍
EDIT: BTW i have a 96 F150 4x4 with THAT engine in it 😆
Do you think I'm gonna leave it stock ? Not a chance brother 👍👍
Awesome story mate
Try doing it with ls heads instead of cleavland heads. The bore spacing would make it easier and there more more parts readily available. That is if you plan on doing something like this. Ive also been playing with flathead brigs scince i was 10, im now 15, but im trying to sqve up for a cheap harbor freight welder to weld the lobes of the cam. Its a briggs 3.5 hp with a Raptor Racing carb off of a 5 hp. Its also an industrial block, so its sleeved.
Cool story. You were one tech savvy teen!
I wonder what you have in mind for that 300i6?
I wasn’t lucky enough to have anyone to help me with my cam on my cart. I made a jig for my cam to lie in and with an old electric sander, I took.060 off of the round part of the lobe. Then, I took a little off of the lobe to round the ramps. Took the valves and put them in an blown up engine and lapped the valves until they were short enough to seat on the new cam. With that, I got my first protest.
man its refreshing meeting another motor guy.
were a dying breed you and i. i wish you luck on your endeavors and if youd ever like to talk to another motor guy it could be fun. i have alot of strange builds ive done/next on the lists.
Bob was a genius. He did things that nobody never even thought of. Gay Wiliams (his carb man) also did things nobody was doing. He still is today. DragBoss on you tube has his own channel and has things from Bob. That is all he does today. You would have to be above the rest to win as many championships that he did. Billy is running in his dad's foot steps. Ronnie.
The plate on the exhaust reminded me of how old school racers cured restrictive exhaust ports on Cleveland heads. I assumed it was just a mod applied to the factory 6 head, the ingenuity involved to build this is mind boggling🤯
Heard of this. Also heard of this being done with 354 hemi heads.. There's also a dude currently building a 300 based stroker with a custom LS head. Can't wait to see it run.
I've never seen a straight 6 like this. Omg this is insane! Subbed bell on!
Best three videos I've seen in a long time. This engine is awesome!!!
That is really awesome, great work on that engine!!
I don’t know if it was the same car but around 1970/71 at a small 1/4 track in PA (Numidia) there was an Altered car from NJ that had this engine combination racing. I don’t remember the guys name. Fast as hell but very weird sounding with the six cylinders. I’m pretty sure it would not have had the cut/raised exhaust ports because I seem to remember that was a Pro Stock modification. I have been looking on/off for info on this engine combination for years. There was a magazine article about this combination during that era and I believe it was called a Boss Six. Thank you so much for providing the videos and it great to know that at least one original example survived.
Joe Williamson ran one for years in the Gas classes (F Gas if I remember correctly); Back when the NHRA encouraged innovation in the Sportsman classes.
I was pretty sure about it being a 300c.i. Ford.
I absolutely had no idea about the canted valve head.
Pretty impressive work.
I also think the drive on the camshaft cover was for a Waterman pump for the fuel injection.
Beautiful, thank you for great content. Please keep up the great work.
Sooo nice to see other people excited about their tradecraft. I feel the same way about Century Electric motors!
Bruce Sizemore is the builder.
Bingo
Mr. Ellison I remember as a young kid (9 or 10) mabey my father explaining verbally and in action in our shop all of the power gaining attributes and modifications done to this ford engine as well as some things that aren't done to it as well, just saying I appreciate the video! By the way my 2 hero's and role models in my life are 1st my father second Bob glidden.
Keep the videos going can’t wait to see you tear it down and show us process
I never would have guessed that. Great design. You should do something different and weld your fav heads together and post it all. I would def watch with amazement. Love engines too.
Just beautiful!!!!
Knew a guy who ran one of these in a 70s Maverick....ridiculously quick car....sounded weird, too. He never told anybody what he had done to.....or why he did it! Just another unknown genius, I guess.
Only guy I knew who ever beat him heads up was running a suspiciously stock looking 383 GTX that ran low thirteens...and he only beat him by a fender length....
Thanks!!!!!
You are absolutely right and I love watching you talk about it. Thanks for your time and effort, I will like and share this with everyone I know. Great day and enjoy your evening, stay warm.
My father-in-law (RIP) was a heck of a dirt track racer in the 60's and 70's. He was a ford mechanic. And he biult and drove for the Dealership he worked for. He won championship running a ford inline6 against all the V8's. He said he could get amazing RPM and torque from his 240ci motor. He used as much 289HO specs for reference as he could for valves and cam specs. He would biuld his own manifolds and exhausts to suit his cam combination and gearing. That old dude was a true racer ! Still drove fast in his Mustang until his final days. I wish I could share this video with him. He would get a kick out of this creation.
Awesome & really cool engine! But it's funny how you were trying to hold back on identifying the motor until later in the video, even though ya forgot about the FORD sticker right there on the front of the engine, lol. I'm assuming that's the water inlet, what is suppose to be the thermostat or water pump housing ..........( just above the harmonic balancer. ) Looking forward to seeing this engine taken apart for closer inspection & descriptions!
the pushrod valley cover is unmistakable
👍🏻👍🏻 Right On Buddy, "Super Cool Build" 💪🏻💪🏻🇺🇸✌🏻
Wow! Amazing! Thank you for sharing this with us!
Ford 300 has a 4.48 bore spacing, 351 Cleveland has a 4.38 bore spacing. It is far enough off that if you welded two heads together you would probably have a problem with intake valve to cylinder wall clearance problems. Very cool engine with a huge amount of work done to it.
From what I have read it took 3 heads to make this work instead of 2 and that's probably why.
It can be done with two heads if you center them on two cylinders. Cut one head in half and use each half on the outer two cylinders. Cut the middle section out but let it be a little longer to make up the difference. The valves will be a little bit offset but not too much.
Awesome!! Can't wait to see it apart man!
Cool thanks for sharing never seen one bin the car repair business for over 45 years with my Brothers started with are dad of course we do drag racing cerntly do automatic trans like you we keep it real thanks
I'm sure you know by now but the Builder/designer of this engine is Sherman Sligh. Fantastic man. There have been several engines like this built over the years. The team of Steve Ambrose and Bob Huetman and Ray Argenta as well as Canadian Ralph Hope ran these until Alan Johnson of Top Fuel fame designed and made a Billet head for them.
Did Hope run his car at St. Thomas dragway?
@@93_LXcpe Raph Hope had his one car, very similar engine though.
@recrdholdr I remember seeing a front engine dragster with this engine combo in it, at St. Thomas dragway a long time ago. I don't recall meeting the car owner, just thinking it was a cool idea
Brilliant work 👀👀👌
Seen a few of these in my day. Those exhaust adapters are the same design Billy Glidden used for years. Not to mention a torque monster. Nice find.
Funny this video popped up, I recently seen other videos about this very same setup using the Cleveland heads.
Those Cleveland heads. On the inline 6 is awesome love it Clevelands rock
We are enjoying it and thank you again for your time and work! My 85 year old Dad said that he remembers it and the poor guy had his car tore up by the NHRA guys looking for how he tried to cheat and tuned it in after the police could be it find any thing. NHRA GUYS ARE STUMPED.
Another awesome video from a teacher of mechanics.
Love that inline Ford, I've been building an racing inlines for 50 years. Started out in 72 on the great Pontiac overhead cam 6. Also did alot of the slant 6s. In the 80s moved onto Toyotas inline, then jeeps. Today we're pushing the 4.0 jeep motor to 1000 h.p.
Did you ever SEE the reputed, never-built in reg production, DOHC 230cu" Pontiac?
@@jackdale9831 never heard of it, but there was a dohc 389 in 63that was done at Pontiac along with a sohc 421 and another that came later. Cannot remember what size though. None of the engines made it to production cars unfortunately.
My guess was a 300 but this is awesome this is absolutely awesome just made my day
I graduated in ‘76. I remember reading about a GM six cylinder having similar surgery. Cutting up 305 or 327 or 350 heads to mount on the block. They were welded together, two combination chambers added to four. This also put intake and exhaust on opposite sides. A few guys at school had hefty six cylinder novas and mustangs. It was the cutting edge, I guess. Thanks for throw back.
Clifford research and development
I remember reading about this in
"Car Craft" magazine back when I was in high school and seeing it run at the local drag strip in a Maverick named "Preparation H" that was reported to run an engine just like this, 300 inch Ford block with sliced and diced 351 Cleveland heads. It was fast as any V8 powered car in its class and put a lot of V8 cars on the trailer scratching their heads and it had a unique exhaust note of a 6 with the resonances of a V8. I've followed you for a long time and I'm glad your the one who got the job of brining it back to life because of the passion you have for your industry.
I a H Modified Production Maverick at Englishtown many years ago, probably 1975 or 76. The owner/driver was Nate Cohen AKA Nazy Crate. I talked to him at length about the engine because I really liked the six bangers and straight 8 dragster like Pete Shadingers straight 8 rail. Nate said "you're looking at a $2000 head. I believe his cylinder head was made from aluminum Cleveland heads. The one in this video was made from cast iron. It took 12 hours of welding with the head heated to 1500 degrees. There is a whole RUclips video on it.
Jimmy Lindsay !!!
I knew that was a 300 6 Ford immediately figured a truck block. The head is where you got me. That's wild!!
Cool stuff is always cool no matter the brand or whatever. Thanks for sharing
Cool stuff!
Wow I’m really interested in learning more about the way they did the head work is old school but so impressive. Can’t wait for the tear down
This kool cant wait to see it running
I had a 1968 Ford 1-1/2 ton truck with a 300 6 banger mated to a 4 speed. That is a workhorse combination. It actually sheared off all the rivets holding the ring gear to the carrier.
Very cool engine!!
Great engine! IMO, the Ford 300 I6 was the best motor ever made for the working man! Extremely reliable, easy to work on, and good for 400,000 miles before a rebuild. I have a 1979 Ford F100 with the 300 that I rebuilt last year. The motor had 412,000 miles on it. I have two more blocks in my garage if anything happens to that one. America was built with the I6 motor!
That is a beautiful piece of machinery and it surprised me I was right at 300 Ford 6 cylinder I was surprised I got that part right but 600 plus horse power oh my God that is a horsepower monster and I love your videos I learned so much and I'm in the process of doing 360 Chrysler motor for a Dodge pickup
That is so awesome I have never seen anything like that, to take something cut it up and make it work in your mind and put together with your hands epic. Bob Glidden is my favorite prostock driver. Me personally would love to here how you started your life as a engine builder then a business owner. Because my big dream was to own a garage. I remember when I was young sneaking out of my back yard and go to the Mobil gas station and watch the guys work on cars, then I was old enough to get a job there then the bug hit me and and I just knew that's all I wanted to do. Then the side of town I lived in everything started to close life moved in I went truck driving, and now at 58 I still love working on my cars and living my dream life though others that got there dream. To me it just doesn't matter what brand it is or what part of the car it is motor,trans,different it's still a work of art and I still get to get my hands on it.
1963 was a great year brother 😆😆👍 I was born 5/5 that year.
You said 310ci. And as soon as I seen the distributor placement and pushrod cover I was thinking 300. But the crossflow head had me doubting. That's a wild engine. Cool stuff for sure. I want to hear it.
Batten Heads, of Romulus, Michigan, built heads like that for Bruce Sizemore's Pinto way back when. They also did head work for AJ Foyt, and many other strong running Indy teams. Nice piece.
C J Batton
Did the only aluminum Oldsmobile head back in the day too
Pretty neat. Speaking on rare engines that produce this kind of horsepower. Have you ever seen a motor built for quarter midget? To race the chillibowl? Literally a v8 cut in half? Would be neat to see you break down one of those engines in a future video.
230 cube ford?
@@1philliph Chevrolet midget motors are old
nascar v8 W/166 CI @ 350hp 4000-9000 rpm range.
Toyota is now the leader though i heard. Over 400hp fron rumors i heard but i haven't seen #'s
A few years back some guys from new Zealand brought their v8 version CNC engine that matched 166ci rules. They let them race and then banned it however.
a roommate of mine in 1979 had an old econoline van w/ a 300 cubic inch straight 6. when I was helping him do valve adjustments and tune up, I had no idea anyone could make a racer out of one.
The 300 strait 6 won the Baja 1000, 3 times.
great video as always ..........thank you very much
Freekn awesome. In line 6s are the best motor to start with. The big issue is the under square poke and stroke. You need some pretty tough rods and crank
im not very good with engines, but I know enough to appreciate this engine. You can see how much time and thought went into customizing it and getting it to put out some crazy power.
That is so cool I haven't seen anything like that since i was about 8 when i started motor rebuilds
The bottom end looked familiar but the head really threw me off. Then you explained it. Good luck and be careful with it those segmented heads already make me nervous.
Really interesting. Would love to see this run.
When John Force talks engines, I’m all ears!! 😂
Awesome! I know of straight 6 engines. But that is a whole different animal.👍
Saw something very similar at the 79 Winstons. I was only a teenager at the time, but I know it was 300 Ford motor with a cut up head. It was in an altered car and was extremely loud. Won his class.
You mentioned Bob Glidden did he run this? Curious about the cam specs. Any idea who did the cam? Has to be a custom grind. I'm mostly a Chevy guy, but I'm still interested in all of them. Like the old school stuff the most. Great channel.
As soon as you said 310 ci I guessed it was a ford 300. That is too cool!!
I thought it looked like a 300 inch ford but that being said, I wouldnt be able to identify a similar Chevy or Mopar. Ive just been around and worked on some of these over the years. Whoever did this had some serious time in it and you are correct, he is an artist
Since i owned a 351 C-4V I recognized the ports my CJ's were open 1.71 exhaust & 2.19 intake
I remember the old days this guy said when someone pulled in with a Ford who new what he was doing it took 250 chevys to out run him
There was one here in San Antonio at T&P Automoive back in the '80. I do not remember all the details of where it came from. We had a 302 with Australian Cleveland heads used in a Oval track car.
I always knew about the power of a straight 6 engine...i had a old 74 ford Van from Telephone Co. and it run like a scaled Dogs...and everybody thought that it was a 8 cylinder...i loved that Van...with that engine...the engine I had was unicorn because of the way it preformed...i could start it up and it would idle the same in any weather without touching the accelerator at all...and could take off even if it was 30 below...it never missed or shut off or anything...its was ready too go at anytime...it run so smooth...i was a unbelievable engine...
I picked the Clevo head but was thinking Jag block. I’m in Aussieland so, as any self-respecting Ford guy of a certain age would, I’ve had a couple of Falcons with Clevos-best sounding V8 I’ve ever had-compared to Windsors and Coyotes since (incl S/C one). My couple of Clevos were generally stock other than one I built, which didn’t go as well as it should have due to massive ports with small cams and carb. Just a silly mismatch due to being young and stupid-but too poor to feed it the juice it needed. I went waaay too small in the carby and cam to let it breathe the way the heads and bottom end could.
Great video 👍 ✅ thank you very much 🙂
Not a Ford fan boy by any means but I guessed a ford 300...one of the best engines produced. IMO...thanks for sharing

Thanks for sharing ❣️
REALLY cool motor.
Show us it running when you your done .Put it on a Dyno ❣️
Hey Ken, Love the video! I knew what it was as soon as you pulled the cover off. This is the same engine build as the one Bruce Sizemore had in his pinto, I think in 1975 and won the prostock championship with it!! I can not remember who he was staged against in the final round, but I do remember it being a white GM car. It is hard to mistake the design of the 300 and then, when you see the Cleveland ports and canted valves up top it is a dead give away!! I love the way they did the front timing cover to drive the enderle pump for the injection system. I know, I am about 9 months late on this post but you said to leave a comment if we recognized what it is. LOL I am a FORD guy and also an engine builder. I love those Cleveland heads. I have got to get caught up on your videos, I have never seen one of these heads off the block. I am also curious about the cam choice, and the way they lightened the crankshaft as well. Thank you for you time. Earl
I first thought e49 engine or Australian falcon engine I was wrong lol but awsome work on motor
