For starters how did you only manage to stroke a 302 to 306...something aint right. AFR's are a pretty good. I would say you need to look into what kind of boost you want to try and make. Then take a SOLID look at how much boost your rotating assembly and block can handle. The rods and main caps being the major weak link. Unless your sporting some nice parts I wouldnt build much more than about 8psi of boost.

With all that being said I would talk to the supercharger guys and see what they think would be a good fit.

You could forgo the supercharger and all the headaches that come with them and buy this set of Yates heads I have. If your running stock block and rotating assembly these heads will make more than enough H.P. to break those parts without any boost. 49cc chambers,all Jesel valve train, titanimum valves (2.125/1.580),keepers,retainers, ported,polished and ready to go. $4500.00 for the pair complete. I'll even throw in a set of exhaust flanges so you can build some new headers.

Just a thought....lol.
