Supercharger on my Gen I 350??

You also might want to look at a little higher stall converter (2k or even 2500) to allow that engine to build a bit more torque. Might also want to put it on a dyno and see what spark curve you have, stock HEI units work great up to 6 grand but the spark curves are all based on the original engine installation and are not a universal setup.

You are better off to stay where you are with the exception of installing a higher stall converter to match your cam specs. Your compression is way too high to use with a blower. There are cam grinds to accommodate the use of a blower but, you will still need to reduce the compression. IMHO, the only thing you need is the higher stall to allow the engine to get into it's power band quicker. The stall speed is usually dependant on the cam specs for a particular engine which determine where the power band is placed. The cam grinder can usually recommend a converter very close to ideal if he knows your engine specs, vehicle weight, tire size and rear gear ratio. If you have a trans with a lockup converter, you may want to consider helping it out with some trans mods. It sounds like you may have a decent setup already. You should also install a good trans cooler if you increase the stall speed. IIWM, and based on y past experiance with blown small blocks, I would forget the blower for your engine. If you are into straightline competition, may I suggest a 125HP NOx kit which your engine should be able to handle with the proper carb and ignition calibrations - lots cheaper than a blower.
