I thought the ZL-1 used open chamber heads.

[/ QUOTE ] Harold and Paul,
The L88 on ebay is equipped with the first design L88 engine. The second design L88 engine which went on production around vin 22000 or mid June of 69 is equipped with the open chamber heads revised camshaft, holley double pumper carb, stronger rod bolts. It is identical to a ZL1 engine except of course for the block material.

Steve,

Are you sure about the 2nd design L-88 using the same cam
as the ZL-1? I thought they were different. Also, the
1st design L-88 would have used the '842 aluminum heads
and the 2nd design would have used the '074 heads - correct?

[/ QUOTE ] I have heard conflicting reports about whether the second design L88s used the ZL1 cam but I was told by someone who is very knowledgable that this was indeed the case. As far as the head castings the first design engines used the 842 heads and the second design engines used the 074 heads.
