Hi, I have a 69 roadrunner, 383, 4speed. Motor has a 480 lift comp cam, 600cfm edlebrock carb and intake as well as headers. All is new. Problem: getting it up to temp and shutting it off and restarting maybe 5 minutes later, starts very hard and if I give it gas, it has a huge backfire, then starts. Runs well otherwise. Never overheats. Any thoughts would br appreciated.
