Re: I want to but a new GM ZL1 block
I can only comment on my 69 block that when I got it home and inspected it I found the main caps had no dowel pins and the new block has as well as splayed caps of a harder material with a logo on the main caps, the aluminum used is a superior grade and harder alloy. Has any one built this block with a 4.375 crank? just curious as to how much clearance is needed in the block to clear this steel rotating assembly.
