  • 2.8 Carb to 3.1 EFI Swap

    I've got a friend swapping out a 2.8 carb motor for a 3.1 EFI in his Blazer. He's got the wire harness and computer from the 3.1 (Camaro).

    What all other parts are necessary to make the 3.1 run?

    Thanks!!

    You need the whole 3.1L engine cuz you need all the sensors... You can use either of the accessories. Basically take the Camaro engine compartment and put it in the blazer.. you will also have to do some adapting of the wiring harness from the old to new.. so get schematics for both.
