Well I got the HEI GM style but it is adjustable I'm guessing it's retarding the time to much. May need a little advance in it. I know at a stop light I need to idle up more it's settling idle now really nice but I noticed if idle up closer with screw 850 to 900. It wants to run higher idle and will jump to 1100 then will calm down pretty sure the cam lope and that advance are the culprit 750 to 800 it's ok but at a light it's can almost die due to low idle. Other issue I cannot get fast idle to work at all cold. That cam on that choke is pissing me off. It's an art I know lol challenge accepted. Choke works but the cam screw was screwed all the way in that can't be right not sure how it got that way.
