You need to give more info, such as compression, blower pressure, exhaust system, what kind of engine you are looking for, all out race engine or a streetable engine. When you have all of that figured out , calla few of the cam companies & see what they can do for you.

 

Try PAW call them with your specs and they will tell you what cam you will need...what compression do you plan on running...keep it low.

 

i can get a set of either 7.6...or an 8.1...yea sorry i didnt put more info to get a real good idea...but i found a place that said a 282/292 would be best suited for turbo/supercharging
