I have a 1991 GMC Cab and chassis c3500 that had a tired 350 and a good 4L80E in it. I pulled out the 350 and set in a new 454 tourque converter and bolted up a machine shop remanufactured 454 from a 1994 c3500.
After I set it in I noticed the 350 TBI wiring harness will not support the eletronic EGR on the 1994 TBI intake. I have the 1994 computer I could use, but I dont believe it will work with without the electronic EGR.
I bought a 454 1994 fuel pump for the fuel tank in the truck as I only have the 1994 TBI.
I also bought the wiring harness adapter to connect the 454 TBI to the wiring 350 harness. I was told I should change manifolds and go to the style EGR that is on the 350 and have a chip made for one of the computers I have.
can I get some advise as how to assemble this mess and truely make it work correctly?
