I have maintained a ZL1 engine log for some time. The casting sequence # [222] would be, by a wide margin, the highest number installed in a production ZL1 Camaro. There should be a number stamped at the top of the rear block face and on each main bearing cap.
Doesn't hurt to check-there may be a VIN stamp on the side of the block adjacent to the oil filter.
My guess, it's an OTC block, built up for racing. Complete engines seem to get $15-$20k; this one is apart so there's that. But, don't see any ugly welds.
