How much timing can be retarded with the std. ford style cap before I have to switch to the pro cap ? . I have a mag 20 , 6 shooter and timing retard and plan on pulling out around 12-13* max . I understand the advantage of the big cap but I am dealing with a hood clearance problem around the small cap now . Thanks for any help .
