Air & fuel that is. would you belive how much of a bitch it is to get an intake to fit a 86 & up 350? its magical how much auto parts stores DONT know. "well it might fit...", is never words i wanna hear. after a call to sumit i now have a working, and non jack legged, intake system. and i found out that when you dont fully assemble a HEI Accel distributor, (previous owner), when you go to start the car all hell breaks loose. So as you can see i frankinstine'd the distributor using a stock Delco ne and what was left of the Accel. it looks better anyhow. once i mount the exaust manifolds properly ill tune it better.
