Re: ZL-1 block versus Can-Am block?
I have a NOS GM Can Am camshaft that is also from Bill Jenkins shop. The most radical cam ever made by GM!

Re: ZL-1 block versus Can-Am block?
The true 'Can-Am' block is the unit Hot Rod magazine did a tech feature on in the Sep 1972 issue: no liners, no fuel pump.
Can-Am racers did not use the standard fuel pump so if an aluminum block has the provision it's not the Can-Am version.

Re: ZL-1 block versus Can-Am block?
If it works, this is the pic Lance 'midyr' posted here previously of some of the stuff he got from Geo. Eaton's CanAm team..

Yenko can am engine
Here is some information on Yenko's ca am engine, I have owned this engine for 40 years, bought from an old drag racer, whose name is long forgotten. The engine now sits in my 1969 camaro, some call it a Yenko ZL1. It has the 4.44 bore with a 454 steel crank, ( near 500 c.i. ) The casting seems to read 3946052, same as a ZL1. I was told this is an early engine, that when Yenko bought the molds, chevy told Don to lose the winter snow flake, but forgot to tell him to change the casting number, which Do did changing it to 3946053. This engine has ZL1 aluminum heads, intake, with a 850 holly carb. pictures to comeAttachment 118460

ZL1 blocks were cast by Winters under two part numbers; 3946052 & 3946053. Production ZL1 Camaros can have either. Yenko did not change it.

My friend has a complete disassembled '73 Can Am engine, aluminium bores, no mech. fuel pump provision. I can take pictures of any particular details if anybody wanted them.

I have had 2 big bore blocks and both were 052 casting and externally identical to a 4.25 block.
