Do CE replacement warranty blocks have vin number also in 1971 big block?
I don't know about a VIN number but here is an interesting old Chevelle forum thread on CE blocks.

"CE" blocks were never stamped with a VIN, as they were meant as warranty replacements. GM wasn't interested in keeping that stuff straight, just getting the vehicle back in service as cheaply as possible.
