yup it will fit done it before. But it will never be thesame engine but it will still get you around the tracks with no problem. Me I did not feel the difference cause I am slow. But for others who knows the engine says it lost some of the punch. I was argueing could not be caused by the rod maybe the bearing or something.
I even used the whole PSR of Go seven port for my nova 7 bt. Engine still runs but eats plugs a lot. They are saying that the go techs piston is flat while the original 7bt is a little convex. Extra shimming did the trick.
