Plenum & Runner Question
I have an opportunity to buy a set of runners, plenum and throttle body from a 1986 Camaro IROC-Z. I'm not as interested in the throttle body as I am the runners and plenum for powder coating to match my valve covers on my 89. Before I do buy them, I just want to make sure they are interchangeable. I'm not interested in going hog wild with aftermarket stuff and the price seems very reasonable for the set up. Any input would be appreciated.

The plenum is specific for '89 and '89 only. For the TPI runners you'll want to pick up a set of 89 or newer because there will be an extra hole in the pre '89 ones for the 9th (cold start) injector which the '89 doesn't have.....or you can tap/plug or weld the extra hole in the pre '89 runner up and then use it. The linkage for throttle bodies is different for pre '89s as well so I don't think you'll want that either....unless you want to change the linkage over yourself. Sounds like you should pass on the deal IMHO.
Look for something for your year it's a lot les trouble and from a Corvette
