Automotive Specialists (automotivespecialists.com ) spent over a year and a half developing this incredibly cool Ford Flathead to go set records on the Bonneville Salt Flats. We're willing to bet this is unlike any other Flathead you've ever seen!

W O W ! ! ! This build was well worth the wait! A 40 minute special, worth every minute! Got to love the Dorten brothers for their innovation and genius. The way the cam is set up with the lockable bearing races, and cam end float.to maximise cam lobe and duration, Is pure innovation. The lifter bores groves to accept roller rockers! And the valve spring retainer lower down the valve stem. Both stout adaptations to help power! The crank hand finished for reduced windage! The cold water inlet right under the centre exhaust port! The list of innovation is the culmination of years of understanding how this naturally restrictive engine works. Enabling the Dorton brothers to excel in designing innovation around the laid down restrictions of this land speed record setter!
I do hope the car dose well at the salt flats!
Thanks for this great video bud! Yet another great watch!!
Thank you very much!
@@TheHorsepowerMonster always welcome bud!!
@@TheHorsepowerMonster Keith Dorton is a Wizard with engines respect back to the Master Keith Dorton from 🇨🇦 #YSW where I follow you 💯 from
Roller rockers??? You mean lifters. Flat heads have no rocker arms!
@@frosteone1670 a highly unintentional grammatical error! Said in the excitement of the moment!
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
"Cutting edge engine tuning work"? On a dyno? For a "land speed car"?
ROFLMAO.
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.
With all the restrictions they had for the build, *257.5lb-ft and 249.4hp* is amazing compared to the original 95hp!
Late Mercurys were 115hp.
those were 95 Big horses.
@@ldnwholesale8552 125 in 52 - 53.
@@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.
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!
I love that land speed records have different classes that allow the tuner to be creative in different ways. I know this was not cheap, but if you have a well kitted garage even weekend warriors can create something impressive with their own sweat equity.
Next breaking 200mph in all motor d16 civic😂
I remember the name ,, John Millner, he's is the main in the movie america garfftti, the Ford high boy 25 bolt was his car. It said he went 157mph. On the lake bed they are running on.
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
The amount of engineering involved in this is incredible. A near 75 year old engine making 250 horsepower is crazy to think about
Here in Japan 1953 Toyota R engine 69 years old with 1mm overbore 1.6L , cnc bearing plate, longer rods and forged shorter comp pistons, custom cam and ported OHV cast iron head made 183hp with boost and injection. 69 years old 1.6L and on a towing tractor absolute freaks.
Hmmm, yet there is engines a year or two newer that make double that. Small block Chev 265 will make 2 hp per ci.
The variety of baby hemis from Mopar divisions. And all with less cubic inches. Or even a Y block Ford.
@@ldnwholesale8552 Totally different engine. OHV heads can breathe. This is a Flat Head. Apples to Oranges!!!
@@ldnwholesale8552 so what ? Your comment is absolutely ignorant, we all know this but that sbc was new technology then, and the sbc cannot compete in this class to compete at Bonneville to possibly set a new world record in this class, try and keep up, and Keith Dorton knows more about making horsepower than you obviously will ever know.
but its not a FLATHEAD!!!!!!!
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.
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.
OMG! Impressive doesn't even come close to the correct word for what these geniuses achieved. A true delight to see these men at work, smarter than smart with many, many years of experience. Thank you so much.
Thanks! And thanks for watching!
Anyone can take a modern engine that has had decades of engineering and evolving done to it but seeing someone take a early designed engine and modernizing it as much as possible well thats just something special and unique i love these type of builds
I can't get over that cam. An amazing build for sure.
Messed up the first O-ring when pushing the cam into place 🤦🏻♂️
This build is absolutely mind blowing! I've never seen a dry sump flathead, let alone one that's been stroked and has all of the custom touches that Keith along with all of these many companies who contributed to this build. I am speechless as to what I've just watched. This is definitely the ultimate flathead build. It's making supercharged flathead power in NA form!
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!
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
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.
👍🏁🇺🇸
I am 26 minutes in right now, and I am speechless. I am so loving the melding of old and new!!!! Thank you for sharing this build with us! Also, 9.2:1 compression on a flathead is bonkers....again, thank you so much!
Edit, again: You would not bore me by posting the testing.... I would absolutely love to see what the power did with other setups, that would be epic.
Yes!
Seconded! Lets see those tests and hear that center headers system.
@@PiDsPagePrototypes I had never seen that til I saw this flathead.
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.
Fascinating build...great explanations/commentary. Well done 👍
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!
That was fantastic ! What a detailed , well engineered build. Thank you so much.
This is unbelievable, my dad drag raced flat heads for many years his biggest problem was the crankshaft flexing and braking. This article would blow his mind if he was still around. Great article absolutely remarkable engineering
That's because they only had three main bearings.
Absolutely gorgeous and amazing engineering!! Beautiful build!
When I was 14-15, my dad gave me a lesson in engine building. I got to rebuild a 1940 flattie for my 1933 ford pickup. Boy was that a good lesson in,life and engine education. It ran really good and smooth. Man, that flattie sure sounds healthy..
this much inovation and creativity can only come from knowledge and a deep passion for performance my hat is off to the Dorten brothers and a thank for letting us watch
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 love this channel and watching this masters at work and checking the solutions they come up with is mind blowing. Thanks a lot indeed.
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 👍
Thanks guys. Always cool to see some old guys make it roll again.
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.
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.
These 2 guys are geniuses. I just love watching there projects.
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.
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
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!
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.
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!
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!
VERY fascinating episode, thanks for putting this together and sharing it with us !!!!
Thanks!
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
Thanks for sharing this! That is so much work and ingenuity. That thing is a sewing machine.
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.
Heck, this is one time I just watched without skipping the video. Highly enjoyable.
Automotive artistry at its best. Hotrodding is alive and well with people like this. Thanks so much for taking us along
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
Amazing work! They make it look so easy. Engine art.
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!!!
Thank you for posting this. I watched every second and was amazed.
I am eager to see the run. Brilliant 👍😎
Thank you very much! It is my longest video yet (by a good amount), but I geeked out over so much of it and just couldn't take any more out.
@@TheHorsepowerMonster h÷?
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
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!
Super interesting video. Jeff and Keith are the greatest guys to work with!
Awesome Video. Really enjoyed all of it. 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!!!
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!
Too Cool! So different from the old flatheads I remember building at Motor Replacement Company, back in the mid-70's... good memories!
Most of this built is brilliant outside the box thinking. Very amazed and impressed. Gotta wonder what else these guys have done that has never seen an audience?
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.
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
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 .
Man that was absolutely great.congratulations.
That cam shaft design is amazing.
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!!!
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.
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
Ron Main's Flatfire is the fastest Blown Fuel Flattie at 302 mph, that record was set at Bonneville in 2003.
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.
This is phenomenal. These guys are geniuses.
Real Rocket Science, amazing build and video is well done. thanks!
Such an awesome build guys!
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!
Great video,Thanks for posting.
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'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!
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.
this is a really cool build ...plus the way they have to make alot of stuff for this build is amazing...
Flabbergasted! Just awesome. Happy New Year.
Same to you! Thanks for watching
I enjoyed that...Crafty old blokes doing what they love...Good stuff.
This is sick. Nice to see it in the car, which is equally amazing.
Great video and awesome engine and build, thank you!
Thanks!
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 😁
Wow!! That is impressive excellent work gents!!!👍
Absolutely awesome content brother
Thanks! And thanks for watching!
this is freaking awesome. absolute mad lads making this beast of a NA flathead.
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. 🇺🇸👍
This is absolutely freaking amazing!
The mind of an engineer and the spirit of an inventor. I'd love to see what he can do without restrictions.
Lots of work guys, pretty amazing results especially for N/A engine more than half a century old flathead, great video!
Thanks!
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.
An awesome video of one wild flatty! Love it.
W O W!!!!! is not a big enough word to describe what the Dorten brothers accomplished!!!!! The engineering, the ingenuity, the pure determination required to make 257/249 torque/hp out of the first mass production V8 is stunning ! This combination in that beautiful car is a show stopper. 🔥🔥👏👏👏👏👏👏👏👏👏 congratulations to everyone involved.
Great video, like the flathead Ford builds. Such a classic look.
Thanks!
I want this in a t-bucket !!!
This is so cool...
I enjoyed this build thanks for sharing
Glad you enjoyed it 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!
Can't wait to see the first build again.
This is a challenge for you to get your hands on a Australian Ford barra motor with a turbo and make over 2000 bhp from a straight inline 6 cylinder
I'm sure the Early Ford V8 Museum in Auburn Indiana would love to have one of these in their collection.
Thun Field Rod and Custom! Beautiful build!
The flathead V-8s have a unique sound. But this one sounds the best out there
