I was talking to a guy at a local machine shop today and he had said an easy way to get more power from my hot air car is to find a 4.1 motor. I was told by him that all the internals are the same it just has a bigger bore. Is taht true? He siad everything will bolt right up to it and no one will ever tell the difference!! Just wonder if anyone has done this with a hot air and if it is even worth the time or money?
