I've been struggling with a problem for a month need some help...Engine came off the dyno running great idling great. Put it in the dragster engine won't idle clean. Three differences: the dyno has a 7AL-2 ignition setup, collector style headers, and a different fuel system. Engine is a 15 to 1 SBC with HFE intake and a dominator. The dragster has a new Mallory HyFire 7C ignition and zoomie headers. I'm starting to question whether zoomie headers may be a problem on a carbureted gas application? or maybe the new ignition has an issue? any thoughts???
