Thanks guys, bought the 3956618 block with machine shop bill for $650, gone over crank, heads (still figuring those out) and a highrise manifold for $600. Still trying to figure out if there should be a VIN code, or if it was a replace/ground off as I see all the other stamps (DZ, casting, date e.t.c) except the VIN. However I am not putting it in a Z28 so I guess it doesn't matter, just curious.

Thanks again for the tips.
