selecting an intake manifold
Hello! I have a '70's 302cid, with a stock 4bbl manifold, a spacer, and an edlebrock 600 or 650cfm carberator, and am looking into purchasing an aftermarket manifold for performance gains that are decent for durability when driving (freeway, cruises, traffic, etc.). So far, I am stuck between Edlebrock Performer, RPM, Victor Jr., and Weiand Stealth, but I do not know much about their specific function, or which would be better for my application. I do plan on adding a mild cam, as long as it won't jeapardize drivability.
As for cams, if I get the Performer, I was thinking of getting the manifold/cam kit package offered by Summit.
Does anyone have any suggestions, or can give me an idea of which manifold would be best for me?
Thank you so much.
