I just completed swapping out a 4.3L Vortex engine with a 350 that I completely rebuilt, same year model. Only differencethat I see is the 350 has a Evaporator Canister Purge Solenoid. I have the manual giving the wire color from the 350 wiring harness. Does anyone know if the wire coming from the ECM come out under the hood in the harness for the V6? I actually started the engine up with the V6 module and it ran fine. I swapped it to correct module and it purr's like a big cat.
