I have 2 original ford C9OX aluminum intakes. One is factory original, the other one has had the intake runners ported, maybe a gasket-match job... not sure. My question, which intake would work best for my current configuration: original bore 289, '70 351 heads (milled), Hooker full-length headers, Autolite 4100 (1.08) carb, Mallory Unilite distributor, coil and Hyfire. Cam is another old Ford Muscle Parts item. The specs are similiar to the HiPo but it's not a solid lifter cam. I believe it's ~ 470 Lift, 290 Duration.
FWIW, tranny is a T-5 and rear gear is 9" 4:11 t-lock.
thanks, Todd.
