    Bore size would have to be considered (piston rock). I run a 4.60 bore and at 9000K it needs at least .070 and still just touches (MGP rods).

    Good point, you will have piston to head slapping going on, machine marks will transfer, etc., and its worse on one bank of the engine (I think the left side, 1, 3, 5, 7)
