i rebuilt my motor (63' 327) and i was wondering what a good starting point is for the idle adjust screws. i have a rochester 4jet (not a quadra jet) the only changes i made from stock are a little bigger cam, roller rockers, and some custom milling on a 283 intake manifold that came with the truck. nothing major- just gave the dual rise more common plenum area to help the a/f mix. other than that is stock specs.
