Did anyone see this:
https://bringatrailer.com/listing/l72-chevrolet-427/
Complete "L72" engine built using a decked 69 427 block with partial VIN stamp 19N637733 by the oil filter. So a block form a COPO Camaro apparently.
124379N637733 hits on the online NMVITIS system as being a car that there has been a title issued and/or a registration issued some time after the NMVITIS system’s beginning coverage date (which I believe was around 2009).
So very possible that the car is still out there.
I posted this info to the auction with a tag to winner of the auction. We will see if the censors at BaT let it post. (They don't particularly like me and censor ALL my posts, because I have pointed out too many fake or transplanted VIN tags on Chevelles in their auctions!)
