Hey guys got a few questions about my 71 mach 1.Its an automatic with 351c 4barrel. Mine has an electronic ignition box. DId these come stock with that or was this added before i got it? Also does anyone know what the stock timing should be? Distributer was out of the car when i got it so i have clue where the timing should be. Is about 24* now and it seems to run better but not exactly right. Any info is appreciated. Thanks alot guys, Brad.
