World's Fastest Flathead? (Going to the Bonneville Salt Flats)

[robertreavley]

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!!

With all the restrictions they had for the build, *257.5lb-ft and 249.4hp* is amazing compared to the original 95hp!

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

[BrotheuZ]

One of the best storytelling on a mechanical car video in a long time. Thank you.😊

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.

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 amount of engineering involved in this is incredible. A near 75 year old engine making 250 horsepower is crazy to think about

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.

[paulplack]

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'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!

[larryross]

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.

[ereisenheim]

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.

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

[Carstuff]

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.

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

[Brock_Landers]

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!

[teddyjones]

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.

[wyattshelton]

I can't get over that cam. An amazing build for sure.

[markwallace]

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

[brendanroberts]

I have been waiting for this one ever since you teased it a while ago!
