OK, so I just installed a new carb in my 79 z28, and she's not so happy about it. I need to get a good solid tune on this carb, and while I can crank a wrench, when it comes to vacuum gauges, I'm lost! Can anyone recommend a good mechanic in the Portland area who's old enough or experienced enough to actually remember how to tune a carb?

its not too difficult, and if you do a search you can find that damon posts a lot of good info for the Qjet. Assuming it is a stock type carb. To tune it right though you also need to know how your motor is set up, (stock, or what kind of mods. ) Quadrajet or aftermarket carb will also make a difference to what kind of tuning you will require. Most carbs will not work right out of the box if you replaced it with another. Let us know what your set up is and it may be just as easy to give it a tweak here and there to dial it in fine.

Aye, there's the rub!! See, the only thing I know about this engine is that the block is the stock 350, but the innards are not. It's got an Edelbrock Performer manifold, and had a Carter carb of undetermined model and size. The guy I bought it from... well, I think the extent of his knowledge regarding engines was something along the lines of, "Well, it turns. Real fast.". I don't know anything about what kind of cam is in there, what compression the pistons are, etc. In the meantime, having no experience tuning a carb, I figured I'd leave it to a pro to get right the first time, and I could tinker with it from there. After calling around, I decided to take it to Hal Jones, over on NE Fremont. He and his shop have been around long enough to have tuned many a carb, even if he may haven't for a while. If anybody's interested, I'll post the results here when I get it back.
Thanks for the info, Steve!
