Can do. He's on an extended weekend vacation, but will be home tomorrow. I'll work on an answer.

VIN stamp. This LT5 perhaps was destined for another 90 Corvette at BG but was diverted to #2299 that would explain the VIN restamp again to document not to deceive. At what point was the LT5 assigned to a ZR-1? how much time is there between assignemnt and installation?

Someone else can answer that better than me. I will recount a story that Ryan B. & I worked on a bit. He acquired a 405 new, crate engine with a build VIN stamped on the engine. We "acquired" the current owners contact info & found out the ZR-1 has a numbers matching engine, WITH THE SAME VIN AS THE CRATE ENGINE. Through a few phone calls we surmised that the first engine was VIN stamped @ BG (like all engines), placed in the car, but on final inspection may have had finish blemishes & was removed & replaced with another engine that was VIN stamped with the same VIN. The removed engine was sent back to MM, then back to GM crate engine inventory, still with the original VIN intact.

So, things do happen that are not in accordance with the standard procedure.

It does not seem plausible that an outside repair shop would go through the effort to restamp the block. Nor would they have access to the correct stamps/fonts etc. So I would think this had to have originated at MM and BG.

Agreed..
