HI Jeff, The 455s are worth more than the 400s. There were fewer of them to start with.
Of course we're talking about building performance engines here. Who knows about the resto market .
You'll need the codes and dates for that.
Make sure the 400s have the 5 mount bolt holes on each side (70 or newer) They'll bolt into more applications (2nd Gen Firebirds)
Say hi to your Dad for me
