Ok, a little more info. My timing is set at 16 deg btdc, add the 4 deg set in the cam and that puts it at 20. Curb idle is set at 1100 rpm, anything lower than that and its is to choppy. Idle vac is 15( will double check this but this is what I remember) .
The 570 holley has 54 jets on the primary and 65 jets on the secondary. PV is 85 and pump shot is 35. The 770 has 69 jets on the primary and 72 jets on the secondary. PV is 65 and pump shot is 25. Idle and vac was the same when I had the 770 on the car. Ignition is a MSD 6AL with Dura Spark dist. I do have the vac advance hooked up. Valve are adjusted at .20 on intake and exhaust. The car starts fine hot or cold and once warmed up idle is fine.
