Seems I didn't let the carb heat soak enough either. Much reduced after the carb gets warm from a longer drive (phenolic spacer) I am also running an open plenum spacer on a dual plane manifold. I might try a half inch 4 hole to replace it and see if that helps. Engine is coming out for...

Okay, floats level good. Idle transfers a bit more than square. I took it for a drive again, same idle dip issues and there is a stumble if I'm just cruising and stomp it, like very aggressively. And not a real bad one. Backed idle screws out a bit, and it seems to have fixed that drop...

Thanks for all the advice. This carb should be close to what it needs in terms of cfm. The factory carb was an 1840c 600cfm. But made for emissions with a 2 stage power valve. Car will just chug along at low speed no bucking. I can mat it pretty low rpm in 1st or 2nd rolling without any...

Thanks for the read suggestion. I'll have to get some longer hose for the vacuum Guage and route it into the car, then go for a drive. Running out of time this season though. Going in for a new rag top pretty quick here.

Okay. I read the calculation was idle vacuum divided in half minus 2. I didn't know there was a giant way to set them. I'll look it up Besides the idle dip when I push the clutch in coming to a stop the car doesn't seem to be overly rich?

Yeah. I won't touch that. It's the stock 6.5 and the car goes like he'll otherwise. Just this small idle dip issue.

Also, let me get my timing light on it to confirm tomorrow also. I know its a bit more than the factory 10*, but not a lot. I wanted the small idle speed increase on the old and tired reverse idle screw 4160 without opening the butterfly more. Why bigger power valve?

1984 was was the first year of efi believe. But it was tbi and not very good(3 years later brought multiport which was much better) It was an option. And worked with almost nothing but stock components. Stock h.o. cam is pretty mild, more than a standard firing order 302 though. But nothing...

Yup. Bone stock 83 h.o. (as h.o. as 1983 gets, but hey it was 180hp up from 145 a few years prior)tree oh two except equal length shorties, 2.5 mandrel bent pipes and thrush mufflers with a H pipe. 18.5 or 19. Depends what Guage I grab from the drawer.. cheapies... Borg warner t5 in it...

Yup. Vac advance is off of spark port. Secondaries are closed. Factory pcv still on and confirmed working. It goes like stink, pump shot works good. (Had to change to the holley squirters with the tubes on them) cruises nice. Smog was removed, including air pump. 1983 galloping horse...

also, we are bit past the factory recommend 10* at idle. To about 13 I think. (Old emissions 4160 that was tired) ill spin it back to factory.

Thanks for the help!

Okay. I'll check the level again. I think it was just under the little viewing port when I checked it. So your saying possibly a bit more throttle screw to open them a bit? Then back off timing to lower the idle? The ports aren't totally square but they aren't alarmingly exposed either

friends car. Not Mopar. But helping cause I like v8s. Holley 4160 (new). Stock small block... No emissions stuff. Trying to get idle dialed in. Steady vac at about 19. Idles pretty consistent. But when you clutch in coming to a light, the idle dips low and comes back up. Is that...

Old folks home I did a nurse call at had a nat gas 225 generator in the basement. Electrical school I attended as a student had a 318 generator which we were replacing at the time with a big Caterpillar.
