Bullseyeprec, you may want to try the pump squirter cams on position #2. Also make sure the pump lever arm screws are adjusted to leave only a slight gap (.003/.005) between the plunger rod and the discharge arm when the car is at idle. Sometimes we have found not enough base ignition timming can cause an off idle hesitation also . Most of our stroker Widsors like between 16/18 deg. initial timming at around 950 to 1000 RPMs Your total advance will probably be at 34/35 deg. You may have to re-curve your distributor to get these results. Check with your engine builder to be sure. Hope this helps.
