I think that for my application, I don't need a lot of carburetor, cam,compression. I'm sure that a compression ratio of around 9 - 9.5:1 is all that I'll need. Selecting the parts so that they work together is the biggest thing, then dialing in the ignition system and the fuel system. Also using the proper size exhaust system is important. A lot of people think that it takes a big carburetor, cam, and a high compression ratio to make power, but it doesn't.
