I run a HP500EFI but my buddy has the carb version. Were trying to think of ways to get more HP without spending lots of course.
The first thing we know we have to do is replace the manifolds with headers, but after that without going to a Wipple we think changing the cam would be our next step. But we don't want to go changing valve springs etc. can it be done. looking for at least 50 HP or so. Does anyone know of any experiments on this engine??
