Well, since they let people start changing bore centers and deck heights, the name on the engine doesn't really mean squat anymore.

Absent this, the winner would probably be decided between the Ford 385 series engine, 4.90 BS, 10.320 deck height and the RB 4.84BS, 10.725 deck height depending on how much crank you can fit in there, even the tall deck Chebby is way behind at 4.84 BS and 9.8 deck height, so you just couldn't get the inches out of it.

If you're cube limited, the Ford is gonna walk away with it, just because you can get more bore and thus more valve and rpm for a given displacement. This is demonstrated by NHRA Pro Stock. S/F.....Ken M
