273 Performance build possibilities.

What I'm saying is, much like AJ, you're throwing numbers out with zero basis in fact. Without knowing what the total combination is, you have no way of knowing power output numbers at any RPM, you're just guessing.
Yes I'm ball parking it to give him some idea of rpm needed, so he can choose if that is acceptable to him not meant to be dead on, why I used about around generally etc.. but it not a total guess is base of other builds of those hp #'s of various cids and lbs-ft per cid I've seen. Not guaranteeing that's where the OP will make it if he chooses so.

And the gearing I picked 110 mph seem like a decent number a lot cars are around, It's again just to give an idea of what he may expect to run at various engine rpms, wasn't picking his gears for him.
