Hi Joe. If you are planning on building a supercharged 350, I would recommend exploring the websites of the major supercharger manufacturers like BDS, Dyers, Whipple, Magnacharger, etc. and see what they have to offer. Then start making calls and planning your combination. Some of these sites offer information about carburetors, camshafts, and ignitions. With a blower, you will want a forged crankshaft and forged pistons that will keep your compression around 8.0:1 and I would consider aftermarket connecting rods such as SCAT I-beams or H-beams. It would also be a good idea to run an MSD Boost Retard unit in order to avoid denonation. Detonation is one of things you absolutely must avoid with a supercharged engine.
