Whats up again everyone I've got a question regarding intake manifolds.. I've got a '79 Trans Am with an Oldsmobile 403. It's got a few mods such as headers, cam and exhaust but its still sporting the stock aluminum intake (at least i think it's stock the casting # is
22528212). I've heard the Performer manifolds don't offer much more power than the stock Olds. Anyone have experience using both?- posted
