I'm an experienced engine tuner myself and I have to say that this right here is some cutting edge engine tuning work, my admiration for these guys ideas and workmanship is off the chart, thank you so much for posting this episode it really has made my day
I'm sure you're a nice guy but most of these mods have been around for quite some time. Adapting them to a flathead is rather rare though. Oh and yes the reverse flow port set up with the exhausts running out the top is not in any way new tech either.
@@deeremeyer1749 I don't understand your comment. Do you realize there are many classifications for LSR attempts? This is a very impressive modified antique engine.
This is a jaw-dropping build, but I'm also finding myself impressed with the factory engineering that went into making this engine affordable in 1932. A great story all the way around!
@@Mercmad That is true. A 95 horsepower flathead seems to outperform a 95 horsepower OVH. Probably because it can use lighter valve springs. Less friction.
I think my 51 mercury Monterey was rated at 112 big horse power I can't imagine rockin 250 that would be a hot rod i would like to hear that through the glasspacks like my exhaust that would be a dirty sounding girl
My Dad raced back in the 1950's. He was one of those "Flathead Guys," while everyone else went SBC. He still won his share and ran Sprints, Midgets and Supermodifieds. His sponsor was the A-1 Brewery, Phoenix. I remember many all nighter flatty builds. Lots of stories.
My father raced a B class car. it was a Chevrolet with a 235 six cylinder. because Chevrolet only had a six cylinder at the time. but it was no match for the offenhouser flatheads.
There is a gentleman just down the road from me who told me his Dad had an engine shop decades ago and specialized in Flathead Fords. After he passed away in the late 70's, they were cleaning out the shop and had to literally throw away 9 complete, rebuilt, and ready to run Flatheads. It was a time when they were worth next to nothing and NO ONE wanted them. Now, rusty old cores usually start around $800-$1000. If they only knew where trends would go!!! Sad.
If this type of work is not inspiring to a younger generation, then I dont know what is. This is incredible and just proves that hot rodding is still alive and well. Awesome job covering this build.
the issue is to allot of us Younger guys (im 25) is 1 Price allot of the "hot rods " are EXTREMELY expensive I've been wanting to get a halfway decent roller of any 70s car it doesn't need to run or even have an engine. just a body that's no Swiss cheese but cant find any for less than 10k from what I've seen. also the EPA cracking down on allot of the aftermarket goodies

I've built many, many flatheads of the single cylinder variety for garden tractor pulling. The cam and head are where you make power. Tiny changes to the cylinder head will make a big difference. We found giant valves actually hurt power as it forces you to lower the compression ratio. It's a fine balance. Fun to build. Enjoyed the video!

Incredible engine. But I really would like to see the first version up and running. Just for the looks it wins everything for me. Hope you guys continue working on it. Cheers from Italy.
So they did do a video on it, which I watched a couple weeks ago, showing a basic high performance overhaul of an original engine. It was an insane amount of work. After watching these videos I no longer want to own a flathead. I still think it's the best looking V8 engine. But the design limitations are far greater than I had imagined, and without serious modifications and without serious attention to detail. The original engine didn't have an oil filter, and requires modification to have one. It seems like you need to have some experience building these engines, otherwise it will probably leak oil, or develop an oiling problem.
There's Nothing to be said that covers the magnificence in this whole process. Wish I coulda had a part of an engine like that in my old 40 two door sedan. Bravo! Thank you all so much for sharing this masterpiece. 👍🏁🇺🇸

Dang these guys are machine gangsters and I absolutely love watching them work. I had a great uncle that was like these guys and turned out some ridiculously awesome things out of his machine shop. Automotive geniuses and I was honored to learn from him. Thank you for sharing and please keep em coming, everyone keep yourselves and love ones safe and healthy.
I love it !!! I’m sure Keith and the guys there did as well trying to find all the Horsepower they could with that engine platform had to be challenging but lots of fun !! It’s easy to make HP with a more traditional build like a Small block or Big block. But making HP with a flat head now that’s where the talent and knowledge shines most !!! Great Content
I'm not a Ford fan nor a flat head fan but this episode just came up as I let youtube roll and was glued to this......great work by everyone and I subbed as well.
I've been waiting for this one for a long time, thanks so much. Such a super clean build hiding an emormous amount of ingenuity, thank the boys at the shop for allowing us to look over their shoulders. And I would love to see where the numbers on that inside-out motor end up after they figure out the metal expansion issues, the better flow on that build will definitely have it making even better power.
That giveaway car is pretty sweet with the LS6 in it!! I used to work at a Corvette resto shop "Billy Bob's Fast Expensive Cars" (yup, that was the name! lol), and this really reminds me of one that I kinda fell in love with working on.. It was/is an "NCRS" car as well. Same year & color (tan interior though) and an LT1 instead of the big block. 2nd, THANKS for sharing this very unique and AWESOME build with us all!! SUPER COOL!
Acquaintance of mine set the Lakester speed record for naturally aspirated flathead Ford in the spirit of Modesto clocking over 300 mph. These speed builds are amazing. Every time you think that’s all there is someone pushes it a little more. Good luck guys Gods speed!
The ingenuity and innovation used in this build is amazing, absolute masters of their craft. Enjoyed every minute of this upload, I know it's not for everyone but I could watch builds like this every day. Cheers
I wish I had the time (and above all the invitation) to hang with guys like this and learn!!! I'm sure they have forgotten more than most of us "gearheads" will ever learn and it pains me to think of all that being lost to life's inevitability.... GODSPEED gentleman!!!
Kudos to All involved. I hope these Gentlemen have several Apprentices soaking All this Knowledge up. May the V-8 Ford live on in our hearts and on our roads. These are for You, Pops.
What a great engine. I had a 1950 F2 Ford with the 239 cubic inch V8 did a complete reman, found a great machine shop. Put in adjustable lifters, made valve adjustments much easier. Bored .030 over, rebuilt the rods, reground crankshaft, resurfaced the flywheel. And had it balanced. For stock applications. It did good , I even got 15 MPG on highway, but top speed was only 60, and it was running pretty high RPM, so mostly I stayed on 2 lane highways and kept speed to 50 MPH
Clarence Everett did this 50 years ago, he stuffed a flathead in a 67 Camaro. I think he hit 136 and change at the flats. Engine building tech has come a long ways in 50 years, your build is over the top.
We rebuilt one of these flat heads in metal shop when I was in high school. The shop teacher had a '51 Ford Truck that had a straight six and we put the flathead in not realizing this dude just had an engine rebuilt and installed for free. It was still a lot of fun.
My god...so labor intensive...the guys @ A.S. are true craftsman...!...its nice to see that some people "still"take pride in what they do...!...It always shows when all is said & done..I cant even imigan the price tag on that build...?...!...great video..hope all goes well @ Bonneville 4 them...keep us posted...Reguards Brian
there is more genius in this one video than most engineering collages around the country. these are men are absolutely amazing. these guys have forgotten more about engines then most people will ever even know. the stories they could tell.
The innovation here is all through this great build. In the old old days, we just bored, polished, saved heads, new pistons, hotter ignition, headers and added carbs for street drags, gearing if we had the means…….this is amazing engineering….Thanks
Liked your video on this motor, very interesting and also informative. As a car and horsepower enthusiast I love to hear the cackle of a race motor at idle but every time the car was at idle, you were talking or playing music over that beautiful sounding motor! Give us a minute or two to relish that pop and snap of open pipes on a built engine, hell just a few seconds would do it! The sound of open exhaust is to gear heads, what catnip is to cats, we love it and can’t get enough! LOL!! Anyhow still liked your vid, thank you and keep them coming.
I can’t agree more!! It was finally idling in a car at the end and I just kept saying shush!!! shush!!! I want to hear it all cammed out in a car idling. Then he stops talking and crappy music started playing…noooooo!!!
Watched the recommended video before I saw your suggestion. Had no good idea about how they even worked in terms of intake/exhaust. Well done video that, and well worth watching.
OMG MIND BLOWN!!! Hello Hello From Canada! I am brand new to your channel but I am so happy I found you. These guys at Automotive Specialists are pure wizards with their approach to building engines. My first video was the classic suburban build, but this build is fantastic. Please let the guys there know that I have never heard of such incredible wisdom and experience sharing as they have here. They are really generous to pass along their expertise with new generations. I hope you and everyone near or dear to are healthy and happy. I can't wait to see more on your channel. Thank you.
THANK YOU SO MUCH. TOTALLY AWSOME ENGINEERING!!!!!!! I LOVE BUUILD LIKE THIS. WHERE YOU TAKE THE BEST OF THE OLD AND COMBINE IT WITH THE BEST OF THE NEW!!! GREAT VIDEO AND EDUCATION!!! THANKS FOR SHARING!!!
This is a great, great video. Excellent camera work, sound, editing and narration. I love these guys and this project. What a great way to spend your time- getting aid to think of the best way to make power within the rules
Great sounding flathead. Thanks for giving us some idling airtime. Us gearheads love to hear these hot motors idling, yet we hear so little of it. I know you've got to follow break-in procedures, but once past that, it's always great to imagine how these builds might sound in our hotrods. And yes, I know this isn't a streetable build, but I mean for the others. 🇺🇸👍
The dorten brothers are on a completely different level! Really cool video! I'm buddy's with Marshall who built the car. I have seen the car not only Is the flat head crazy but the car is absolutely gorgeous! It's show car quality. Super cool.
I absolutely hate ford company, vehicles, and dealers, but this is amazing. The engineer in me gets excited seeing all the little innovations coming together into a whole package.
So cool! Way before my time but you have to Love the innovation and thought that went into this build. Super smart builders. Would love to work for them
Exactly! To be honest, if I see another 1000hp turbo LS motor in a Miata I’ll be sick. There’s something more genuine about _EARNING_ every last drop of power and not just throwing money and eBay parts at it.
In my teens I had a 39 Std Coupe with a 296 flattie and since those days of 50 years ago I have often wondered how the exhaust ports could be improved to get more torque .The approach taken here is just like the Cadillac flattie design .
This is an amazing build. As a guy who graduated in the 1960's, these old flatheads were around, and we all had a few. Now they are rare(er) and used where there is an opportunity, like Bonnie. Love the thinking that went into these builds. A few years ago I went to a pretty big local car show and ran into Jack Roush with a flathead Ford coupe set up for roundy round dirt track nostalgia racing. He offered to fire it up. His build, out of his engine shop. Absolutely could not believe how nasty that motor sounded. More like an angry SBC. Loped and crackled like a modern motor. I ask him about specs and he just smiled ... All these older engine builders started by playing with Flathead Fords. And they have had time to think of ways to get more power 😁
Just a great video from start to finish, honestly, one of the best productions I have ever seen on RUclips. Great job guys on both the engine build, innovations and the production quality. I've been to Bonneville twice as crew for a small motorcycle race team and this dredges up some great memories.
I know this is 11 months old but this was an excellent video! I love engine builders re-engineering "under dog" engines into real performers! One favorite is the Polysphere Dodge engine of the early 60's. There was an engine build of one of those engines on "Engine Masters". Incredibly horse power numbers! Those engine builders are true masters with that Flat Head engine! 👍
YEAH!! I love old things I'm a chebby but I love great work and this Engine got it. I had a 53 F100 sedan delivery that I bought for $35 bucks for a parts chaser, It had a 239 in it and it was well broken in when i got it. I was 17 and it was a pice of junk but just right for my wallet I drove it for four years then it through a rod on the freeway (it shoulda never been on the freeway and it would have gone a lote farther. Wish id have been able to clean it up like a lot of rust buckets i got about 15 years later the value started climbing a lot oh well! Man these guys are really imaginative in their tricks I did light machine work like valve seats and guides. but building your own rollers and the bearings for the cam thats amazing! Great Work and great story thanks for sharing. edit I'd love to hear about that Ardun headed motor wold like to see what that Legendary motor can do. It was before my time in hot rod Magazine only Italians were more exotic OHCs woah! Cheers
I've been avoiding this in my feed. It was a mistake. I watched every second. A triumph over adversity racing class this one and triumph you did. That was fun. Cheers for posting.
I have a flathead powered MG-TD which I created in 1957, Merc OD transmission, 56 Ford rear end. The car has crossed the US seven times, been deeply into Mexico, and a long way north in Canada. For the past thirty-five years it has been based in Europe, in Gotland, Sweden mostly, from there driven far north as the Shetlands, south to Florence, Italy. Except for building the engine for modern lubricants and fuel, no one has done any work on the car but me. (Even rattle-can painted it over the years). The old “bus” fits me like a coat; to ride in, even MG-TD owners can not tell the car is not original - well till I hit the gas ! The car has never failed in any way and total repair cost for sixty-five years in continuous use is less than two thousand Euros. Now that I will return to Europe perhaps it’s time to convert to electric, though I hate to consider retiring my old flatheaded friend. {Incidentally my first girlfriend bought the car for me to re-assemble: her girlfriends brother started to put in a Chrysler but got drafted. Girlfriend got impatient with my learning curve and bought a Plymouth; haven’t seen either since I was seventeen - doubt if the Plymouth is still in service}
I am in absolute awe of what has been done here. Wow!!!! I have never questioned the number of head bolts. They have a LOT of space to cover, and a (relatively) thin piece of metal to hold down. So it makes complete sense (just like with a lawnmower flat head) to have a lot of bolts. I am amazed with this engine!
Being a techno freak i loved watching this video and it brought back fond memories of myself and my godbrothers rebuilding old cars mostly 1928 to 1960, we didn't make them into hot rods but put them back to factory spec. and sold them - if we found a buyer
WOW! knowing what I know about engines, flathead included I am impressed with the time and effort put forth in a project like this and I am sure that it will be a complete and utter resounding success1
I've been looking forward to watching this video for a long time. Thanks! Edit: This engine is even cooler than I imagined! It looks like a flathead designed by Gordon Murray.
I have a flatty in my 41 Ford Tudor Sedan about 20' away. My Grand Dad retired from Ford in 75, he was Chief of Dyno's at Dearborn Engineering. During 60's and early 70's I went to many events with him and he knew every driver that ever drove a Ford with factory backing and was a NASCAR devotee.
Imagine the time and expense just to win a record. Back in 1950, my Dad's '39 Ford Coupe with a blown flathead ran 114 mph at El Mirage in what they called the flying mile. It was also his daily driver.
My grandpa ran moonshine in a 39 and 40 Ford coupe from the mountains of TN to the foothills of NC every week. They ditched the flatheads and started messing with the big Cadillac engines in the 1940s. Grandpa never got caught hauling whiskey either lol.
Thats really impressive for 1950 and a street car. Affordable V8 engines were just coming out like Oldsmobiles OHV 303 and with a lot of work and a blower they were getting repectical horsepower right after that dodge released the Hemis and the horsepower race was on. But for any young man a blower and acc is a pretty expensive propsition but oh the heart pounding fun
Incredible the amount of design and work that went into this flat head ! The flat head was in the infancy of hot rodding and to think today engineers have designed a normally aspirated piston engine to produce 670 HP . Great job guys , really enjoyed this video .
SPEECHLESS !!!!!!!! This my friend is the most uplifting and informative video of Flathead race engines Ive ever seen ! And now I have to rip my flathead engine out and do it properly !! Thank you 🙂
The second truck I had as a teenager was a 49 Ford with a flathead V-8. Yes, it was a hunk of junk but I drove it anyway. That truck, along with a dozen or so other cars, were on some property we bought in the backwoods of Arkansas. After the truck gave out and was returned to the car graveyard we had, I pulled the hood off and used it as a sled pulled behind the tractor. Couple of kids in the sled and I'm trying my best to sling them out. Great fun!
My first car was a 1949 Ford 2 door business coupe that my Dad bought new and gave me in 1969. The flat head V-8 ran like a charm. I wish that I still had that car.

I've built many, many flatheads of the single cylinder variety for garden tractor pulling. The cam and head are where you make power. Tiny changes to the cylinder head will make a big difference. We found giant valves actually hurt power as it forces you to lower the compression ratio. It's a fine balance. Fun to build. Enjoyed the video!
i agree,we also found torque improvements by increasing intake speeds (narrowing the intake passage) briggs running on methanol.
It IS a very fine balance with an L-head Briggs....
The more you make room for airflow after the intake valve, the less compression you get....

Automotive geniuses and I was honored to learn from him. Thank you for sharing and please keep em coming, everyone keep yourselves and love ones safe and healthy.
I love it !!! I’m sure Keith and the guys there did as well trying to find all the Horsepower they could with that engine platform had to be challenging but lots of fun !! It’s easy to make HP with a more traditional build like a Small block or Big block. But making HP with a flat head now that’s where the talent and knowledge shines most !!! Great Content
I'm not a Ford fan nor a flat head fan but this episode just came up as I let youtube roll and was glued to this......great work by everyone and I subbed as well.
Thanks for watching!
I've been waiting for this one for a long time, thanks so much. Such a super clean build hiding an emormous amount of ingenuity, thank the boys at the shop for allowing us to look over their shoulders.
And I would love to see where the numbers on that inside-out motor end up after they figure out the metal expansion issues, the better flow on that build will definitely have it making even better power.
That was fantastic ! What a detailed , well engineered build. Thank you so much.
That giveaway car is pretty sweet with the LS6 in it!! I used to work at a Corvette resto shop "Billy Bob's Fast Expensive Cars" (yup, that was the name! lol), and this really reminds me of one that I kinda fell in love with working on.. It was/is an "NCRS" car as well. Same year & color (tan interior though) and an LT1 instead of the big block.
2nd, THANKS for sharing this very unique and AWESOME build with us all!! SUPER COOL!
I have been waiting for this one ever since you teased it a while ago!
Sorry it took so long. Hopefully, it will be worth the wait!
Automotive artistry at its best. Hotrodding is alive and well with people like this. Thanks so much for taking us along
Acquaintance of mine set the Lakester speed record for naturally aspirated flathead Ford in the spirit of Modesto clocking over 300 mph. These speed builds are amazing. Every time you think that’s all there is someone pushes it a little more. Good luck guys Gods speed!
These 2 guys are geniuses. I just love watching there projects.
Fascinating build on the engine and great camera work showing us all the innovation needed to overcome t
Thanks a lot!
Well done mate one of the best tuning/build videos I've seen. Informative and engaging start to finish you should be proud.
Hey, thanks a lot! And thanks for watching!
@@TheHorsepowerMonster you are an amazing narrator sir!
The ingenuity and innovation used in this build is amazing, absolute masters of their craft.
Enjoyed every minute of this upload, I know it's not for everyone but I could watch builds like this every day. Cheers
Thanks guys. Always cool to see some old guys make it roll again.
Heck, this is one time I just watched without skipping the video. Highly enjoyable.
One of the best sounding engines ever made.
That's exactly what it is sound because it sure the hell don't make any power lol.
It has a free flowing intake, and little valvetrain weight...shows how important exhaust flow can be...
@@kskip4242 it _don’t?_
@@_..-.._..-.._ the flatties made under 100 horsepower when they were new.
I wish I had the time (and above all the invitation) to hang with guys like this and learn!!! I'm sure they have forgotten more than most of us "gearheads" will ever learn and it pains me to think of all that being lost to life's inevitability.... GODSPEED gentleman!!!
Kudos to All involved. I hope these Gentlemen have several Apprentices soaking All this Knowledge up. May the V-8 Ford live on in our hearts and on our roads. These are for You, Pops.
Very impressive build.
I can see there was a great deal of time in development.
Thanks for the story and to Keith and sharing.
Take care, EM.
This was over the top a great build. The vid was very well done and narrated.
I drove a 1950 Ford with a flat head to many years ago to talk about.
What a great engine. I had a 1950 F2 Ford with the 239 cubic inch V8 did a complete reman, found a great machine shop. Put in adjustable lifters, made valve adjustments much easier. Bored .030 over, rebuilt the rods, reground crankshaft, resurfaced the flywheel. And had it balanced. For stock applications. It did good , I even got 15 MPG on highway, but top speed was only 60, and it was running pretty high RPM, so mostly I stayed on 2 lane highways and kept speed to 50 MPH
Outstanding! I simply loved every second of your coverage of these Masters at work! What a treat they so generously gave.
Thank you very much!
Clarence Everett did this 50 years ago, he stuffed a flathead in a 67 Camaro. I think he hit 136 and change at the flats. Engine building tech has come a long ways in 50 years, your build is over the top.
That cam shaft design is amazing.
One of the most interesting engine builds I've seen! Love to see the reverse exhaust setup when they get it heads modified. Thanks for the video 👍
We rebuilt one of these flat heads in metal shop when I was in high school. The shop teacher had a '51 Ford Truck that had a straight six and we put the flathead in not realizing this dude just had an engine rebuilt and installed for free. It was still a lot of fun.
You get paid in knowledge and expirience.
Thanks for sharing this! That is so much work and ingenuity. That thing is a sewing machine.
My god...so labor intensive...the guys @ A.S. are true craftsman...!...its nice to see that some people "still"take pride in what they do...!...It always shows when all is said & done..I cant even imigan the price tag on that build...?...!...great video..hope all goes well @ Bonneville 4 them...keep us posted...Reguards Brian
there is more genius in this one video than most engineering collages around the country. these are men are absolutely amazing. these guys have forgotten more about engines then most people will ever even know. the stories they could tell.
The innovation here is all through this great build. In the old old days, we just bored, polished, saved heads, new pistons, hotter ignition, headers and added carbs for street drags, gearing if we had the means…….this is amazing engineering….Thanks
I enjoyed that...Crafty old blokes doing what they love...Good stuff.
Absolutely gorgeous and amazing engineering!! Beautiful build!
Liked your video on this motor, very interesting and also informative. As a car and horsepower enthusiast I love to hear the cackle of a race motor at idle but every time the car was at idle, you were talking or playing music over that beautiful sounding motor! Give us a minute or two to relish that pop and snap of open pipes on a built engine, hell just a few seconds would do it! The sound of open exhaust is to gear heads, what catnip is to cats, we love it and can’t get enough! LOL!! Anyhow still liked your vid, thank you and keep them coming.
I can’t agree more!! It was finally idling in a car at the end and I just kept saying shush!!! shush!!! I want to hear it all cammed out in a car idling. Then he stops talking and crappy music started playing…noooooo!!!
Watched the recommended video before I saw your suggestion. Had no good idea about how they even worked in terms of intake/exhaust. Well done video that, and well worth watching.
OMG MIND BLOWN!!! Hello Hello From Canada! I am brand new to your channel but I am so happy I found you. These guys at Automotive Specialists are pure wizards with their approach to building engines. My first video was the classic suburban build, but this build is fantastic. Please let the guys there know that I have never heard of such incredible wisdom and experience sharing as they have here. They are really generous to pass along their expertise with new generations. I hope you and everyone near or dear to are healthy and happy. I can't wait to see more on your channel. Thank you.
Thanks for the kind words! And thanks for watching!
WOW lots of detail engineering. Thanks
THANK YOU SO MUCH. TOTALLY AWSOME ENGINEERING!!!!!!! I LOVE BUUILD LIKE THIS. WHERE YOU TAKE THE BEST OF THE OLD AND COMBINE IT WITH THE BEST OF THE NEW!!! GREAT VIDEO AND EDUCATION!!! THANKS FOR SHARING!!!
Too Cool! So different from the old flatheads I remember building at Motor Replacement Company, back in the mid-70's... good memories!
This is a great, great video. Excellent camera work, sound, editing and narration. I love these guys and this project. What a great way to spend your time- getting aid to think of the best way to make power within the rules
Thanks very much!
Great sounding flathead. Thanks for giving us some idling airtime. Us gearheads love to hear these hot motors idling, yet we hear so little of it. I know you've got to follow break-in procedures, but once past that, it's always great to imagine how these builds might sound in our hotrods. And yes, I know this isn't a streetable build, but I mean for the others. 🇺🇸👍
The dorten brothers are on a completely different level! Really cool video! I'm buddy's with Marshall who built the car. I have seen the car not only Is the flat head crazy but the car is absolutely gorgeous! It's show car quality. Super cool.
I absolutely hate ford company, vehicles, and dealers, but this is amazing. The engineer in me gets excited seeing all the little innovations coming together into a whole package.
So cool! Way before my time but you have to Love the innovation and thought that went into this build. Super smart builders. Would love to work for them
I love max effort NA builds. The ingenuity and creativity that goes into them is astounding.
Exactly! To be honest, if I see another 1000hp turbo LS motor in a Miata I’ll be sick. There’s something more genuine about _EARNING_ every last drop of power and not just throwing money and eBay parts at it.
In my teens I had a 39 Std Coupe with a 296 flattie and since those days of 50 years ago I have often wondered how the exhaust ports could be improved to get more torque .The approach taken here is just like the Cadillac flattie design .
This is an amazing build. As a guy who graduated in the 1960's, these old flatheads were around, and we all had a few. Now they are rare(er) and used where there is an opportunity, like Bonnie. Love the thinking that went into these builds.
A few years ago I went to a pretty big local car show and ran into Jack Roush with a flathead Ford coupe set up for roundy round dirt track nostalgia racing. He offered to fire it up. His build, out of his engine shop. Absolutely could not believe how nasty that motor sounded. More like an angry SBC. Loped and crackled like a modern motor. I ask him about specs and he just smiled ... All these older engine builders started by playing with Flathead Fords. And they have had time to think of ways to get more power 😁
Just a great video from start to finish, honestly, one of the best productions I have ever seen on RUclips. Great job guys on both the engine build, innovations and the production quality. I've been to Bonneville twice as crew for a small motorcycle race team and this dredges up some great memories.
Amazing work! They make it look so easy. Engine art.
Super interesting video. Jeff and Keith are the greatest guys to work with!
I know this is 11 months old but this was an excellent video! I love engine builders re-engineering "under dog" engines into real performers! One favorite is the Polysphere Dodge engine of the early 60's. There was an engine build of one of those engines on "Engine Masters". Incredibly horse power numbers!
Those engine builders are true masters with that Flat Head engine! 👍
This is phenomenal. These guys are geniuses.
Its not about why we do it , its cause we can , what a great build and crew
I love this channel and watching this masters at work and checking the solutions they come up with is mind blowing. Thanks a lot indeed.
It is awesome to watch real engine builders in their element.
YEAH!! I love old things I'm a chebby but I love great work and this Engine got it. I had a 53 F100 sedan delivery that I bought for $35 bucks for a parts chaser, It had a 239 in it and it was well broken in when i got it. I was 17 and it was a pice of junk but just right for my wallet I drove it for four years then it through a rod on the freeway (it shoulda never been on the freeway and it would have gone a lote farther. Wish id have been able to clean it up like a lot of rust buckets i got about 15 years later the value started climbing a lot oh well!
Man these guys are really imaginative in their tricks I did light machine work like valve seats and guides. but building your own rollers and the bearings for the cam thats amazing! Great Work and great story thanks for sharing. edit I'd love to hear about that Ardun headed motor wold like to see what that Legendary motor can do. It was before my time in hot rod Magazine only Italians were more exotic OHCs woah! Cheers
Fascinating build...great explanations/commentary. Well done 👍
I've been avoiding this in my feed. It was a mistake. I watched every second. A triumph over adversity racing class this one and triumph you did. That was fun.
Cheers for posting.
Thank you very much!
Ron Main's Flatfire is the fastest Blown Fuel Flattie at 302 mph, that record was set at Bonneville in 2003.
I have a flathead powered MG-TD which I created in 1957, Merc OD transmission, 56 Ford rear end. The car has crossed the US seven times, been deeply into Mexico, and a long way north in Canada. For the past thirty-five years it has been based in Europe, in Gotland, Sweden mostly, from there driven far north as the Shetlands, south to Florence, Italy. Except for building the engine for modern lubricants and fuel, no one has done any work on the car but me. (Even rattle-can painted it over the years). The old “bus” fits me like a coat; to ride in, even MG-TD owners can not tell the car is not original - well till I hit the gas ! The car has never failed in any way and total repair cost for sixty-five years in continuous use is less than two thousand Euros. Now that I will return to Europe perhaps it’s time to convert to electric, though I hate to consider retiring my old flatheaded friend. {Incidentally my first girlfriend bought the car for me to re-assemble: her girlfriends brother started to put in a Chrysler but got drafted. Girlfriend got impatient with my learning curve and bought a Plymouth; haven’t seen either since I was seventeen - doubt if the Plymouth is still in service}
This is sick. Nice to see it in the car, which is equally amazing.
I am in absolute awe of what has been done here. Wow!!!!
I have never questioned the number of head bolts. They have a LOT of space to cover, and a (relatively) thin piece of metal to hold down. So it makes complete sense (just like with a lawnmower flat head) to have a lot of bolts.
I am amazed with this engine!
Being a techno freak i loved watching this video and it brought back fond memories of myself and my godbrothers rebuilding old cars mostly 1928 to 1960, we didn't make them into hot rods but put them back to factory spec. and sold them - if we found a buyer
WOW! knowing what I know about engines, flathead included I am impressed with the time and effort put forth in a project like this and I am sure that it will be a complete and utter resounding success1
That was most excellent, my compliment to the builders.
VERY fascinating episode, thanks for putting this together and sharing it with us !!!!
Thanks!
this dude is simply a master of his craft.
I've been looking forward to watching this video for a long time. Thanks!
Edit: This engine is even cooler than I imagined! It looks like a flathead designed by Gordon Murray.
this is freaking awesome. absolute mad lads making this beast of a NA flathead.
I have a flatty in my 41 Ford Tudor Sedan about 20' away. My Grand Dad retired from Ford in 75, he was Chief of Dyno's at Dearborn Engineering. During 60's and early 70's I went to many events with him and he knew every driver that ever drove a Ford with factory backing and was a NASCAR devotee.
Imagine the time and expense just to win a record. Back in 1950, my Dad's '39 Ford Coupe with a blown flathead ran 114 mph at El Mirage in what they called the flying mile. It was also his daily driver.
My grandpa ran moonshine in a 39 and 40 Ford coupe from the mountains of TN to the foothills of NC every week. They ditched the flatheads and started messing with the big Cadillac engines in the 1940s. Grandpa never got caught hauling whiskey either lol.
Thats really impressive for 1950 and a street car. Affordable V8 engines were just coming out like Oldsmobiles OHV 303 and with a lot of work and a blower they were getting repectical horsepower right after that dodge released the Hemis and the horsepower race was on. But for any young man a blower and acc is a pretty expensive propsition but oh the heart pounding fun
Incredible the amount of design and work that went into this flat head ! The flat head was in the infancy of hot rodding and to think today engineers have designed a normally aspirated piston engine to produce 670 HP . Great job guys , really enjoyed this video .
Thanks a lot ! And thanks for watching!
SPEECHLESS !!!!!!!! This my friend is the most uplifting and informative video of Flathead race engines Ive ever seen ! And now I have to rip my flathead engine out and do it properly !! Thank you 🙂
Thank you very much! And thanks for watching!
The second truck I had as a teenager was a 49 Ford with a flathead V-8. Yes, it was a hunk of junk but I drove it anyway.
That truck, along with a dozen or so other cars, were on some property we bought in the backwoods of Arkansas.
After the truck gave out and was returned to the car graveyard we had, I pulled the hood off and used it as a sled pulled behind the tractor. Couple of kids in the sled and I'm trying my best to sling them out. Great fun!
Nice. A super powerful lawnmower style v8 ready to kick some butt on the salt flats. Good job gents!
I’m dying to see the return of that intake and header combo of the first engine!
Thun Field Rod and Custom! Beautiful build!
My first car was a 1949 Ford 2 door business coupe that my Dad bought new and gave me in 1969. The flat head V-8 ran like a charm. I wish that I still had that car.
Just built a 239 stroker, these cats ARE the real deal. Wish I had the resources to play like that!
Man that was absolutely great.congratulations.
