OK guys... I searched for this but didn't really find anything.
I am looking for a TPI unit for my 350. My question is what year should I go with for the TPI itself (plenum, runners, etc..), ecm, and harness, etc...

I've heard to use an '85 TPI with a '90-'92 corvette harness and ecm (speed density) setup... But is this correct? Any help would be great!
Thanks,
KC
