    In response to Bradfordjlenz

I put a gen IV 454 (71-73) in my impala. about 450hp on pump gas 10.1 compression. Same external dimensions as a 396/427BB. To the untrained eye look the same or can be made to.

my rebuilt 454 was $2800 with non roller,cast iron oval port heads and aluminum intake, no carb,pullies,exhaust etc..

And they are easier to find rebuilt at 1/2 the price of an actual 60s 427...
