I hope someone can help, I'm starting to get frustrated. I've got a 318 .030 over, 10.7:1, 284 deg .484 lift, 650 holley, dual plane, polished heads w/1.94 intakes, chrysler ignition, 13/4 headers, 727 w/ 3500 stall. The problem is it will not idle under about 1100 in park. The cam is pretty rough so that is understandable. When I put it in gear the engine dies. I've drilled 1/16 holes in the butterflies to no avail. I got it idle finally by setting the base timing at 25 degrees, but then total timing is about 50. Way too much. I don't know if there is something I'm missing with the carb or if it is something I'm overlooking. Sometimes it will be idleing and start to stumble like it's losing vacuum signal. Any help would be great
