double carb setup installed (looking for advice)
they both got pcv nippled, and the car holds the same steady high rpm idle and in gear without touching throttle. revs higher than the normal shidt point before shifts and it shifts rough.it lurches and wants to run away. it will hold the rpm i acellerate to even after i let off throttle after shifting
Yeah all that transmission stuff should go away after you fix the throttle problem.
I suppose that you have checked that the throttles do NOT actually rub on the intake openings Nor on any gaskets and that the fast-idle cam is not/are not sticking, right? You may have to tie the chokes open, and/or back off the Fast-idle screws. On those carbs, the fast-idle cam has a tendency to stick. My cure is always to take it off and rub the rust out of the pivot bore, and off the screw, then reinstall it without oil. Sometimes I have had to add a weight zip-tied on the Link-rod. I have used long bolts.
Oh I forgot, does your car still have a rotating throttle linkage?
or have you converted it to a pull-cable?
Cuz that factory rotating system may never work right in this application, especially if the gas pedal pivot on the floor is rusty and sticking.
I only ever had one car with that system, a 64 V100 wagon, and it wasn't long until I stuffed a 340 in there and hung a later model cable in it. Lemmee think, that was about 1975.
