CFI to 4bbl 82-Z28
I have bought a 82 Z28 CFI for 1500 bucks (very nice cond.) that had been converted to a Rochester Quadrajet. It does not use any computer controls and the distributor had been changed to reflect that. My question is, I want to replace the old carb with a new Rochester Qj but don't want all the connections that a "82" would have. I would like an older model that would have a minimum of vaccum ports and an older style choke. Any suggestions would be helpfull.
PS. I did get the original CFI set-up from the guy and will restore motor at a later date.

For a new Q-Jet carb, Edelbrock is one source.
Consider a Holley 6210 instead. It's a 650, manual secondary, spreadbore carb, that uses the style of choke that was on cars up to about 71 ("divorced"), it hooks right up to the factory choke linkage when used with a 69-70 model intake. I've run many of them over the years with excellent success.

RB, you are the very first person I have ever in my entire life heard say that they had any success with that spreadbore Holley.
Is your middle name "Midas", by any chance?

Maybe so!!!
I love that series of carbs. Every single one of them I've ever known or had, ran like a scalded dog. I've had 3 or 4 of them myself, and I know several other people with them too. I always used to look for them at swap meets. My late little brother and I put one of ours (not sure whether it was one of his or one of mine) on his 87 MC SS along with a ZZ3 distributor a couple of months before he got killed in it, I couldn't believe how much more power that car had. I run the 6210's big brother 6211 (800 CFM) on my 400. They're easy to calibrate, get great gas mileage when set up right, and of course ya gotta love that manual secondary Holley power.
The vacuum secondary versions suck by comparison. I had (I think) a 9895, I never could get it the way I liked it. Of course that was an emissions piece whereas the 6210 is all about pure 60s power. I like the older ones with metering blocks instead of plates.
