ZL1 block I.D.?

[black69]

Mike Gillipse (spelling may be off) in indiana that used to work at the dealer, has a listing of all the engines produced. You can find him through the yenko stinger connection search. I have an engine with similar attributes, and the key is that stamping in the timing cover area. Not many of these I have seen out there. Some without the stamps would be the engines cast without Yenko approval (and this supposidly happened due to yenko not meeting the forcast he predicted for these). I dont think many of these exist or survived.
