I've thought about throwing an engine together with higher compression, some homemade port work in the head and a cam. But the rods would most likely stay stock. My question is: Would this not make much more power, do you need the higher than stock redline revs to make power even with some more compression and air flow?

 

what kind of cams

 

It's a sohc, and probably just a mild street one since I would be staying at the stock rev limit.
