I wanna lose the 4bbl carter on my 322 nailhead,as its starting to act up... ideally i'd like to use a holley or edelbrock...maybe a 650 - 700 cfm...anybody know the part number for the carbs i'm lookin for??? also will they hook up to the orignal inlet or do i gotta change that sucker too?... i dont mind over carbing it a lil...i know those old buicks dont mind bein over carb'd provided it aint too drastic....any advice ?
