Technical 21 stud flathead engine's show what you have

The post for photos of 21 stud 'only' flathead speed parts/ motor pics

 

I have a complete 21 stud with clear plug wires. It is for sale too!

 

Running one in my T. Stock...for now but she's low miles and runs like a sewing machine!! I love these little flatties!

 

Here's my '37 21 stud. Stock bore, top end is seized up but the valley is full of oil and sludge and i imagine the bottom end isn't too different so if i can hole saw the pistons it should at least turn over.

I've got the same ally heads on it, along with an Edelbrock Super Dual manifold for it and a crab dizzy. Still need to find a 2 bolt timing cover.

 

From memory yes on the four bangers, don't know about V8-60. These guys - www.montereyspeedandsport.com - have quite a few rare reproductions and a few 21 stud and V8-60 in the mix. Aside from them the only other aftermarket 21 stud stuff is the super rare copper Federal Mogul heads. Or the Ford aluminium that we have.. not quite aftermarket but not "stock cast iron" as such.

 

I just sold my Av8 project. It has a '37 21 stud engine. The buyer has found some new Sharp alloy heads made by H&H Flatheads. They look real good. I looked all over for aftermarket heads and couldn't find any.

 

A friend of mine has an NOS set of Evans 21 stud heads hanging on his wall.

 

HAD A PAIR OF CYCLONE HEADS, TRADED THEM TO KEVIN FOR A PAIR OF HIS FIRST 24 STD. HEADS YEARS AGO. JUST PUT A EARLY EDLBROCK SLINGSHOT ON MY 8BA BLOCK , A LOT OF HOLES DONT LINE UP, WERE THESE MANIFOLDS MADE FOR THE 21 STUD HEADS? ARE THE INTAKE BOLTS DIFFERENT ON 59AB AND 21 STUD?

 

For some reason, the 8BA's don't use as many bolts on the intake as the earlier engines. I've never had a problem with an 8BA having excessive vacuum leaks. Any of you accountant types out there able to figure out how much money Ford saved by not drilling and tapping 4 bolt holes on millions of engines?

The guy who bought my AV8 roadster lives in England and emailed me about a stash of 21 stud parts he could buy. There were some of these Allard heads there. The big problem was he had to buy a whole shed full of parts to get them. As he is moving to Australia soon he didn't buy the parts but it is very interesting they even existed.

 

not sure but it might have had more to do with no longer using aluminum manifolds from the factory...

Here's a shot of my Evans block letter 21 stud heads.

 

Found these in a friend's lockup. Not got a motor to put them on, so they're going up on my wall!

 

I have a complete "78" engine dressed as a 34 with trans that nobody seems to want to give me money for.....

 

Bump with pictures for those who have or want to build a 21 stud!

 

I have a set of NOS Bohnalite heads from the Miller- Ford Indy program.

 

I'm putting together a '37 flathead right now.
Show me some more speed equipment I can't afford!

 

Thanks 303!

It takes a lots of searching and saving! Then after you find what you need, you don't pass it up!
Believe me, my parts were all purchased at different times in the span of a few years!

Some really nice stuff you guys have , love seeing pictures . The intakes /heads have such a cool look to them.
Looks like i have some hunting to do .

 

Is this your engine? I have the exact set of heads and I missing the water necks so I will have fab my own. My question is how the water pumps work? Can post more photos of this engine please?

 

Hey
I need to asked, is the 37,38 the only engines that have the speed equipment I have a 36 and was thinking of trying to find some speed equipment for that engine but the water pumps are on the front of the head

I have this in my 36 was told it was out of a 37 and it runs probably will end up selling it ! But for now makes moving the coupe around easy !!

 

it's kind of funny that this thread came up. i have been thinking about building a '23 t gow job and have a very nice '33-'34 motor with the stock ally heads. i also have the whole running gear. everybody tells me to use the later motors but this motor is in excellent shape. doesn't really need anything so i will probably use it. i don't need it to have any race stuff in it so no machining is required.
