I just got a 91 LS and im planing on putting in a 96 LS motor with alot less miles. Im going to put my 91 Intake manifold, distributor and alternator on the 96 and use my 91 wiring harness and ECU. Are there any other things I would have to do to complete this swap? I know the 96 Is OBD2 and the 91 is OBD0 but since im using all my 91 stuff i dont need a conversion harness.
Thanx

 

You will also needto swap out the drivers side mount bracket (using the 91).
You will have to extend the wiring for the rad fan (behind block near oil filter on 91, on thermostat housing of the 96).

You can use the 96 manifold, and just put the 91 parts on it, whichever you feel is easier to do. The 96 manifold I think has a bit larger port size, but it is not much.

That is about all that I can think of from the top of my head.

 

thanx alot
