Stop in for a cup of coffee
I have like 5 months before I can run the car again other than in thr garage, no True hurry. Thank Matt. I will check out those threads. There is a sight called MaxPerformance. On there a several decade long Holley engineer who had some great info also, mine just didn't line up with his info for the slots. Then possible idle speed adjustment with the secondary screw. Also, 660s have a vacuum port plug to the secondaries that is often used to have air bleed instead of drilling blades.
