drag racing induction sys

Were these 1/8 or 1/4 mile runs? Who built the engine? Was it dyno'd? What rockers are on it? You should have big traction issues and you don't. I doubt its the suspension or tires. I'd start with the basics: Compression test, leak down, etc. It's not the carb or fuel system. It's seems to be a turd from "go".
