The 454 was never factory installed in a Nova. The largest engine the factory installed was the 396 in 1968, 1969 and 1970 only. However, like others have said, any big block will easily fit a 3rd or 4th gen Nova.I am totally ignorant of 4th gen Novas so I have to ask the experts here, at Steves. Was the 454 an engine option for the 1976 Nova?
