Yep, I'd pick a Rochester, too, if I could! The local track specifies not only the brand of carburetor, but the part number, too! BTW, I just edited the former post for the correct part number. It's a #7448! There's also a 500 CFM 2-BBL Holley that will breathe a little better, but our myopic tech crew won't pass that one!
