Ok guys Im new to this forum but I need some help. I have a 1970 mach 1 with a 72 351 cleveland CJ engine. It has a weind excelerator intake, mallory unlite distributor(mechanical), MSD coil, comp cam with 260 intake/268 exhaust at .050 duration and a .683 gross lift. it has been dynoed at 528 hp. the problem im getting is after installing it in my mach 1 is I cant seem to get the ideal to stay were i set it. I set it at 750 rpms, and part of the time it stops at 1000 to 1200 rpms after I rev it up or go down the road. I have switch carbs from an edelbrock 800(1413) to and edelbrock 600(1405) and finally back to and old holley 600. It doesnt seem as bad with the holley but it still is doing it. So what do I do to eliminate my problem.. please help out... thanks...
sorry its so long.......
