it was made on 11/21 and it was the 48190th one of that model or body. so it was something that had a bit over 100k total build run. my swag is a pick up trruck engine since that is where most of the 454's came from. also possible impala or caprice engine. 73, i think. no more 454 in chevelle or camaro. never in nova. don't think anything bigger than 402 went in monte bombs. and i doubt anybody would restamp a 250 hp 454. especially when there is no body with matching vin. possibly upgraded when it went into the boat. but it left some assy plant in a car or truck.
