I am trying to convert carb to TPI and recently purchaced, TPI w/harness& ECM, less some sensers, privately. I'm almost possitive the system and harrness is from an 87' 5.7L. Wondering if ECM & Chip is correct? Where can I link to check some referrence #? Any info. would be appreciated :) Inncedently El Camino is an 87' w/5.7 & 700R4

Here's a link to some of the ECM's GM used for fuel injection:
