I would think you need to figure out the exact purpose of the car. Autocross or road track would be a big one. Then build around that. A high RPM screamer would probably be wonderful for a long road track, not as useful on a short turn to turn autocross track. You'd have to have it at high RPM which would make gearing incredibly important, similar to racing a 2-stroke motorcycle.
I, personally, love the planning stages of the build. It's only limited by your imagination and, of course, budget. The better planned out build will always make a guy happier in the end, when everything is perfect! Plan away!!!!

That all depends on the course. The Goodguys layouts generally have 1 or 2 very slow corners so you need to be in first coming out. Unless you are a racing hero (or paddle shifters) you can't shift 4 times a lap, so RPMs are your friend for higher top speeds. I would love to build a high winding small block for my Falcon.
I am working on a model A which I have a DOHC 4.6 linclon motor for. I got some cams and valve springs for it so it should spin up to 7200. Even if it quits making power at 5900, the extra RPM will keep me off the limiter for a couple more seconds.
