what 454 is this?

Before you start pawning off the engine,check to see the dates on the heads and intake.If they are within a month or two before the build date of the car,and he is fairly sure it is a bigblock car,maybe it is the numbers matching top end.I think the 375 hp 396 and the LS6 might have had the same heads and intake,but different camshafts.If the car ate a short blok early on,it could have been replaced with a lower performance one with all the high po stff added on.
