Re: NOS zl1 motor 13,999.00
Stefano, I do know alot of the 053 crate blocks are serial numbered and have a certain run. I believe there were 2 or 3 "runs",some had blue screw in freeze plugs and some orange etc. I know the block i have was the first run gm came out with a while back and has a serial number out of total built,but thats all i know about the newer blocks.
