Did the V6 have fuel injection? What kind - TBI, MPFI, etc?

What sort of fuel injection have you got on the V8?

Appreciate help. The v6 is carbureted and the v8 I am installing will be carbureted.
Thanks, Jay

Hmmm.. If they're both carbureted, there isn't going to be much that's controlled by that ECM. Maybe an electric fuel pump.. I think the electric fan is run from a temp. switch on the intake manifold. The tach signal is going to be different, but you should be able to fix that with a little fancy soldering - I think you only have to replce a capacitor on the circuit board of the tach (if you have one)

I don't know.. I would hook it up as close to the original V6 as I could and see what happened.
