I got a pretty good example. We ran Top Stock with a 360 w/ported Edlebrocks, an 850 good carb and it performed well. When the DP's came along, we added FI bungs on the manifold, changed from an QAF 850 to a 1000 CFM throttle body and we were now fuel injected. Same motor, same cam, same everything. It made about 10 or 15 less peak hp, which surprised us. Spoke to Wilson Manifolds. They said quite normal because the fuel starts atomizing in the carb, and the injector is down in the runner. Also said the total management with the FI system makes it better overall, but more technical. Then when NASCAR got FI, the injectors are in the top of the runner, which I think would be legal in NHRA SS. We will get around to trying that someday. My 2 cents
