I just bought a 72 3/4 ton 4 by and I want to inject it. I got a computer and tbi unit offf a 91 4.3 sitting in my garage and I wondered if it would work and be big enough for the motor.

I also allready have a howell pump and adapter to use a square bore manifold.

Thanks for the help

All you will need is the chips out of a 350 puter. It's best to get some chips burned for the motor/vehicle combo to get the best performance. Find the thread about having chips burned in the Gen 4x4 section to find out more about it.

EDIT: The TBI itself is identical to what is on a V8 TBI, but you will have to swap the injectors to match the flow to the demands of the bigger motor.
