Hi , my post might be a bit long. I just put in a new 360 in my 73 Duster. I had the engine builder install a Ready To Run MSD distributor also a MSD blaster 2 coil. They broke in the cam, also did a dyno test. So I have it installed the motor will only run while the key is in the run position. Now with the ready to run distributor I don't need the ballast resister. I hooked it two different ways, according to the directions from MSD. So I really could use some help and any ideas are appreciated . Thanks Mike
