he parts suppliers have a small a adapter kit that allows the B carb to align properly.

If you think of the engine as half of a 400 cubic " V8 it's easy to see how under carburetor the engine actually is!

Great point! Maybe I should look for a four banger blower. Now we're talkin' SLEEPER

Talking about HP.

Does anyone know the difference in the Burtz 6.5 HP vs Snyder's 6.1HP?

nkaminar · 12-01-2023, 11:09 AM

From my experience there is a little boost going from the Snyder's 5.5 to the Burtz 6.5. In my opinion, the Snyder's 6.1 head has a better combustion chamber design than the Snyder's 5.5 or the Burtz 6.5 so it might be better than either of those, but I don't have any data to back that up.

Synder’s 6.1 head is 6.0 compression ( in their catalog 6:1) and their 5.5:1 if anyone cares

years ago I bought a 5.5 head from Snyder's only to find it was approx. 1/8"-3/16" too short in front and rear. I'm just wondering if this still exists? Of course they refunded my money and paid for shipping both ways!

Hi, just checking HP threads, what carb would you add with a Synder 6:1 head. This engine has 2k miles on it from it's complete rebuild. thanks!

I like the way mine runs with a Tillotson. It is my only experience, so it could be mediocre in reality.

Either a Stromberg 81 or 97 or the Weber that is commonly used today. I once ran the Auburn hill climb in my '30 tudor. I had run it first with a stock B engine with stock A carb. A few months later I changed to a Winfield 6:1 head, the time was a full second quicker up the hill. That same day I switched to a Stromberg 81, times were almost another second quicker. The next time I ran that hill I had changed to a 97 carb, times were 3/10s of a second quicker. I love to experiment like that. That car got really quick when I installed my 4-port Riley in it!

I was just going to post to watch out for the top end. Be sure there is adequate clearance between the head and the piston. The original and many reproductions had a recess in the head above the piston. Many high compression heads lack this recess. If the top of your block has been machined a couple of times you could have a problem when the piston pops up above the block..
