Has anyone done a carb to TBI swap. I have recently obtain a 90 gm truck intake, ecm, wirining harness and all sensors. I will either be placing this in a 79 chevy truck or fitting it to an oldsmobile motor, depending on what would be involved.
You'll need a higher pressure pump, a return line to the fuel tank, all the wiring and ecm will be needed. If your going to use the intake manifold from the 90's truck you'll have to have it redrilled for the older style heads, however there are companies which offer manifolds for the TBI designed for the older heads.
Its fairy straight forward. You might need a different style oil pressure sensor as yours might not clear the back of the intake manifold (mine didn't on my TPI swap).
Im sure im forgetting some stuff but its late lol. I'll remember tomorrow or someone else will chime in.
