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?

I would think an EGR block off would make it idle lower.

Is your vacuum pod on your dizzy good? No holes or anything?

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.

I'll check again, but it does hold vacuum. The second dizzy I have is apparently from a 318 (most likely the original 318 the truck came with), and it holds as well.

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.

I thought that there are only two primary sizes, not including the 1000 cfm compitition carb?

I've got a 2141, which is off a 76 440. It is quite possible they only had two sizes and I'm wrong. I just find it kind of hard to believe Chrysler put an 800 on a 360, is all. lol


As for good cruising mpg....hehehe.....don't even ask me about mine.

If that's the oddest thing Chrysler did, I'd be very surprised! I'll try to back track where I had read that for you.

Just curious, do you have the 3 piece accelerator linkage? If so, got a return spring on it? I have the 3 piece linkage and I had put a return spring on it...when it was on there the throttle would stick partially open.
