Carburetor cfm calculator

The Performer intake isn't totally worthless. It's a bit better than stock and aluminum, too. I've seen some on 11 second cars. lol For a stock to relatively moderate build, they're a good choice. If I didn't have an intake at all, I'd honestly probably look for something different, but if I had one, I wouldn't go out of my way to replace it.
Has stock 2 barrel. Would I be better off buying a performer rpm rather than the performer? It's going to be a mild build, cam probably have a duration of 224*max. Is 9.5 enough compression
