Gentlemen, We have a 383 motor with Edelbrock alum. heads, alum. manifold, BG Demon carb, Mallory ignition, and a Mopar .533 cam, and an ATI dampner. When trying to time it with two different timing lights, it shows 50 degrees at idle. If we try to bring it back to initial timing around 12 to 14 degrees, the motor won't run. If you try to total time it at 2500, the timing marks keep advancing more. Can't figure out why we can't time it at idle or total time it. The timing marks on the crank and cam are right so what do you think is wrong and causing this? It also won't idle slower than around 1200 at idle and going into gear it stalls the motor. Checked for vacuum leaks and found none. Any ideas?
