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.

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!

From the images, the keyway in the cam gear are in different positions relative to the bolt holes.
I'll need to check it before I buy.
Now, where is my Schneider cam?

I was able to get the engine running again about a month ago. Still ran a bit rough, but the water pump didn't seem to be pumping water, so I shut it down. I have the front of the engine and engine bay all disassembled. There is some rusty sludge in the head and rusty water in the radiator. But the water in the block is clear.

Yes, the Sunbird is wearing newer 15x8 Snowflake, but older Radial T/A's - I posted something on the 5-lug Yukon axle swap back in December - viewtopic.php?f=1&t=29255HI WINDING MONZA wrote:OMG, Tom's avatar is sporting new shoes and its up on all fours!
