As some of you know I have been chasing an off idle stumble. This happens from a dead stop (medium to hard acceleration) and when cruising as I hit the throttle. I have a Mallory Unilite Comp 9000 distributor ( mechanical / breaker- less) in a 350 Chevy motor (8.5/1 compression,a mild performance cam, headers,air gap manifold, 670 Holley). It has been suggested that a distributor with vacuum advance (HEI) would eliminate this hesitation because the advance would come in much smoother and sooner. And that the Unilite that I am using is really for a much healthier engine and one with a higher RPM range. What do you boys think?
