I know im beating a dead horse (sorry PETA people) but i need some help. So some reason every time I go looking through the Pantheon of gbody information on this site I can't seem to find a direct or somewhat agreed upon answer on whether or not the factory computer is still needed after an engine swap in a G-Body Oldsmobile Cutlass. I ask because I'm swapping out my tired Olds 260/TH350C for a Olds 350/TH350 that I've built. I'm also doing away with the air conditioning and installing a factory heater only box.
