I just came up on a manifold off a yukon with a 3bolt TB at 87mm i beleive, with fuel rail and injectors for 40$ bucks off of craigslist, this set up is drive by cable but some years were DBW, If i can get a DBW TB for this manifold then I think im going to run it , if not ill have some parts to sell..

What year? I'm pretty sure you just bought the same intake/TB that's on your truck right now...
