Ok , so I bumped back the timing to 10*BTDC and that did smooth out the idle a little. I now have a Holley 650 with mech 2nds on it. When I put the vac gauge ot it, it fluttered around 10 then increased to around 15-17 when I reved it. I hit the books again and founf some more on the subject. It said that running big cams with small carbs will produce this. I'll try the 750 again. But I had similar problems with that one also. Jeez how big a carb do I need? I figured the 750 was a little big but I could live with it. 800? 850? or should I just cut to the chase a buy a ******* Dominator!?
