What I have now, I'm pretty disgusted with. Weiand intake and Edlebrock carb. Milage is fur da birdies!!! I'm thinking of a Preformer intake and a 500-650 Q-jet carb, OR A TPI system. A TPI would be more expensive, but would pretty much guarantee better milage. Anyone know of a GOOD TPI system that includes the harness and the computer chip???
