'69 Z28...Forgive me if this has been covered before but am new to the life. I have a spare engine block that came with a beautiful restoration. The spare block was reported to be the original block but another DZ engine is in the car to save the original. Casting #s all make sense for type of block and build date as an engine about a month older than the car. HOWEVER, where I am expecting a vehicle specific VIN, there is only build data ( VO829DZ ). There are no numbers near the oil filter. 1. Am I screwed?
2. If someone was going to re-stamp a shaved pad is there any reason why they would not include a sequence #?
