With good back pressure and that center pipe is glowing red lol

351 Cleveland uses Windsor mounts. 351 M and 400 are 460 mounts

Definitely v8 😅

Chevrolet's are a lot simpler a lot less b.S.

Lots of experience and knowledge in this fella!👏🏼👏🏼🤠

Ford junk

Inertia batery

That is too cool!

The two inside cylinders share the middle port

Flatheads are a compromise between airflow or compression.

That block looks nicely machined brother.😉 Thanks for saving history and treating it with respect.

Good, because I just put an aluminum flywheel in my 6 spd Camaro and haven't tried it out yet.

For an OHV V8 with 3 ports get an AMC Gen 1 (e.g. 250, 287, 327) 😃 Just be sure to pay attention to the firing order! 😅

Is it a V8 or a V6.....? Its both.........The Heavenly Kid

So Henry,,use two pieces where everyone else uses three, you will see more throughout the fords

The hands of a hard working man !! God bless

This is all about fuel mixture and why a smaller than you think carburetor for the engine performs way better. At the VERY top of the RPM band maybe not but unless you are running wide open 100% of the time, velocity is king.

Crank and cam gear driven little short pushrods.Conservation of space.

Also they sound amazing

I'm a freak for simplicity of the 2.6 and the 2.8 60 degree v6. Strangely the 2.6 would bury 7000rpm electric tach with Siamese setup while 2.8 was slower?

Would carbon buildup be more of an issue without the exhaust valves?

That's the way my MGB is 4 cylinder with three exhaust pipes

Hemi' seem to Get All the ❤, How about an " Max Wedge " Fan Fest 🤔

My dad raced sprint cars in the fifties and sixties. He loved to play puzzle with motors.

1973 Capri 2.6 v6 has a Siamese port and a single on the head.1974 2.8 three ports per head.😎

I had a Plymouth Neon from canada once. With only a light weight flywheel from a rebuild and that car was snappy af for a stock 4cylinder. I took stock vtechs no problem. And nobody could believe it was only because of that flywheel.

A lot of Pontiac headers have three tubes with the center tube being larger to encompass the Siamesed center ports.

And it’s still original. 🙏

I would LOVE to know what the simplest and longest lasting engine is, in the opinions of older mechanics. A lot of people say it's the Ford 300 I6. What do you guys think?

Really nice car fine congratulations but when I was younger I would say yeah bucket seats but now that I'm older I'm leaning towards the bench seat in the front, Way more nostalgia and plus when you're on a date that she's sitting by the door you can whip the car around and make her slide right under your arm where she belongs if you don't have a ton of crap out of damn seat lol

More exhaust sports would mean more horsepower. I guess not so here

Henry didn't pass math

Amazing work!!

I remember my dad talking about milling out a channel above the valves for a big cam in his flat head Merc. Said it was for flow, not the lift.

This cat is so smart. As always i enjoy listening to so much ❤

Terrible engine

I've always wanted to port the hell outta a flathead& put a turbo on it. Obviously I've been told it's blasphemy for years..... But maybe one day I'll get around to it lol

Why couldn’t that be done with all pick-ups?

I think these dam things are nostalgic but that's about it. They can't produce much more than 275 horses N/A nowadays at most. There down fall was that dam exhaust heat to transfer straight into cooling jackets but that's just was the design in those days that was the hot rodding engine of the day they made countless intakes for this motor in the day just to try, and make more ponies, It was unreal. I myself wouldn't want the machining, parts, and maintaining expense and heating problems with a engine like this. I love the way they sound and unique look.

MAKES PERFECT SENSE

Ed said, that man don't have a clue what I'm saying!

The old Siamese ports gets em every time

Like a boat

That is a beautiful piece of History and they sound so amazing

This man is absolutely a wealth of knowledge.. That's a machinist❤

When practicality trumped safety every day of the week

Don't forget the 8 lug axles!

Matt Helm !!

High bank speedway engines harmonic vibrations are a big issue, not just horsepower at speed. Minimize vibration in the RPM of continuous operation rather than an overall average. Valve train issues are the most problematic, especially springs.

I have a 1956 buick roadmaster. Where are you located and how much would it cost
