I'm looking at a '55 hardtop with a 454 BBC that is .70 over with a 1/4 inch stroke. It has Eagle "H" rods, Eagle forged crank, SRP 10.5:1 pistons, Dart hi-rise, Big Brodie aluminum heads and Comp Magnum cam (don't know the duration). I've never heard of a .70 over 454, how far out can they be bored? What cubic inch displacement would this be? TIA.
