2 to 4 bbl swap issues

Yep, I set the mix screws with a vacuum gauge and tach. At idle (850ish rpm) it pulls 18 abouts. The things been apart so many times I'm certain it's clean as a whistle. I did notice that the threaded pipe part in the manifold under the carb is still sitting on the bench, but since the EGR is blocked off, I don't think that would cause trouble?

Well, the TQ was used on 360's from the factory (even on 318's I've read), due to the vacuum operated air valve on the secondaries, it can't over carburate. It will only allow what the engine can demand. The intake I have came off an '81 RC, and from what I found online, it came with the TQ. Some in the mid '80's had the Qjet, but that's well past everything in be got in my set up, engine and parts range from '73ish to '81.

The TQ was used, but not the variant you have. You've most likely got this one:
Model Application Pri. Sec. Rod Bore Kit
9058 76 440 AT F IE (4006631) 4099 5137 2109 1-1/2 2
That's what I've got. The primaries are 1 1/2 inchers on the 440. All overs were 1 3/8s and I'm thinking the small blocks were 1 1/4.

Mine is a 9036, it is off a 440 truck. From eveything I read about the TQs, it seemed it didn't matter about the cfms on the pimary side, the difference between the two wouldn't make much difference since they're so small compared to even some two bbls. That's why alot of people like them I guess, small primaries make for good cruising mpg, even over the two bbls. Unless I got bad info in it, which is possible I suppose.
