Iam looking at a 1984 chevy 3+3 dually with a 454 thats in real good shape for a decent price. I believe it has a holley carb on it now. I was wondering how much of an improvement in power and mileage I could get with the edelbrock pro flow system over the carb. Or would there be a increase in mileage if a put a Q-jet on it instead and how much? Thanks for the info.
