I was wanting to buy the D.S.S. PRO BULLET 331 Short Block needed some help figuring out what to machine the engine to. Here is a list of some of the things that I already have. A Trick Flow Box-R upper/lower manifold, an 80mm Mass air sensor, 30 something LB injectors, (been a while,) an MSD Billet distributor, Flow Master exhaust system and a BBK cold air induction kit. I have already bought BBK Shorty headers, an electric fan, an F303 cam and BBK underdrive pulleys. Everything else is stock. I need to know what type of heads and pistons to get and what the compressio should be. I want to go with an X cam now but don't know how to go about that either. Along with that I also want to get a supercharger down the road. Also the fuel system I have for it is archaic and needs to be dealt with. Any help at all is greatly appreciated.
