Well to get those kind of HP numbers you are pretty much looking at going with a cub and if I were you I would get in touch with one of the engine builders on here and tell them what you are wanting to do and ask how they would set the motor up. You can call Redline, M&M, F.A.S.T. or other good builder and they will be able to tell you what the best combination is going to be for the kind of motor you are wanting to build. Running 95hp on pump gas in a challenge all its own so I think talking to a builder is going to be your best bet. Just my .02
