I plan to install a Mopar Performance electronic ignition setup on my 1970 Satellite, 383 engine that still has the stock point type distributor in it. My question is, will I need to buy a new coil or can I use the old existing one? I thought I read it needed to be changed for one compatible with electronic ignition? If so, Can I just get one from a 73 Chrysler or something that originally had electronic ignition or will I need a performance one? What do you guys recommend? This is not a race car, just a sunday cruiser...stock 383 with a 2-bbl. Thanks!
