I won't argue that, but that was not what I meant. I guess I might not have said it very clearly though. What I meant was that if you built a 318 up to where it was 1.5 HP per CI you'd have 477 HP. If you built a 360 up to yield 1.5 HP per CI you'd have 540 HP. A difference of 63 HP. 1.5 HP per CI is doable in a small block Mopar. Can you imagine a 477HP 318 in a 4 door Valiant? Talk about a Sleeper.
