I have a stock 94 e 350 15pass. van i got for my wife. After driving it abit, I found Ive grown fond of it. My question is what can i do to upgrade power in it(grunt not hp) without screwing up its stock goodness. I plan to put a MSD complete kit. I want to keep stock manifolds and sound, but other then that all is game. I dont know much about this injec. so any help would be cool.
