Awesome. I was wondering this, myself. I've been seeing complete H.O. intakes with TB's on Craigslist going for dirt cheap (like $40 to $60), and I've been thinking about throwing one on my '86 for a couple extra horses, but I didn't want to screw with torquing and re-torquing the lower intake manifold - the upper plenum I can pull and have the other one on in like 30 minutes.
