hello all, Thanks for the reply's I've been at work last couple days, I did have a DP 650 holley, now I have a 600 vac sec holley on it, still backfires on rapid acc, also I"m not the best on the timing? with the vac advance plugged the timing marks balancer and zero on timing cover line up. with it plugged to carb base it moves to very top of timing cover marks?? I think this would be advanced?? if i go the other way you can here the cam better but car runs bad and will backfire a lot more, I'm a little lost. thanks again for all the great replies let me no on any more ideas. Thanks Kelly
