That goes along with what someone -who used to build up 2.5 motors for dirt track cars- said. They said the Non crossflow head was what you wanted if you were going to hot rod one.
Marco,
The Pontiac Super Duty cross-flow aluminum head is worthy alternative.
Well, I've been trying to start my 77 Sunbird(no longer a "3-wheeler"), but the engine seems to be locked up. Sort of.
I took out the spark plugs and I can turn the engine by hand. But, it gets to a spot where it won't turn.
I can put a wrench on it and work it back and forth and then get it past this 'locked' spot. I can then turn it by hand again.
Could be some rust in the cylinder walls. So, I squirted some oil in there. I'll try again later.
I found out that the teeth on the cam gear tend to break off on this engine.
So, maybe that is the problem.
Regardless, I plan to rebuild the engine better than stock an need an alternative to this:

So, I started with the Cloyes web site and found a ductile iron cam gear and steel crank gear set - P/N 8-1018. Nice.

But, there is an aluminum cam gear on the 181 marine engine in a previous post in this thread (back a couple of pages).
The Chevrolet 230/250 I6 engine is listed as an application for the uses the same Cloyes P/N 8-1018.
So, searching the Cloyes website using a 65 Chevy Biscayne 230 L-6 reveals what I'm looking for - it's P/N 8-1016:

As a bonus, the gears are helical cut, so it will not be as noisy.
As a double bonus, this Cloyes 8-1016 gear set is also much cheaper than the Cloyes 8-1018 gear set!

I'll need to check it before I buy.
Now, where is my Schneider cam?
