I would keep the lightning dist & use MSD on the rest , i have a 95 302HO and i use the msd 6al with blaster tfi coil , msd , cap rotor & wires & works great for me . If your truck runs ok now you should be good , i see in your sig you have ported heads & custom cam , i asume its still SD . A wideband AF gauge & fuel press gauge will help you keep an eye on how the trucks running , you can use a tunner like a tweecer unless your like me not very good at computer tunning , i had my truck tunned by a good tunner & helped a ton ...
