The last I heard, polishing the bores of a carburetor or throttle body or anything that fuel and air goes through is a waste. Supposedly the slick smooth surface allows the fuel particles to pool up instead of being atomized efficiently. I've heard from a lot of different people that the best surface for something like that is acheived by getting everything perfectly smooth, and then lightly rubbing it with a scotch-brite pad. :dunno: That's just what I've been told, but if you have a '96 or newer truck, since the TB is dry, I would think that a polish wouldn't hurt a thing.
Edit: I see you have a '96 now. :cool:

Yeah I have the 96 with the dry TB, I just got a new 75mm TB w/o the restrictor on it, so I figured I'd polish it up before I install. what's the best compound to do that with?

Invest in some fine sandpaper, you'll prolly need a piece of 800, 1200, and 1500. Spray it with wd-40 to use as a lubricant, and every time you move to a higher grit, sand all the scratches from the previous grit out. Once you get to 1500, it should be pretty shiny but still have visible scratches, now it's time to polish. I use Mother's mag and aluminum polish and a polishing towel.
