I have done alot of research on this particular case and here is what I have discovered with you only running 7-8 inches of vacuum your TQ now thinks it is on a much smaller engine. Carter and Edelbrock carbs. were designed to run with 12 inches on up. The reason your idle is so low is because your not pulling in enough air and gas into the intake thru your idle circuts. The idle air bleeds are too small and you would most likely have to go to bigger jets to compensate for the low vacuum that is not pulling enough fuel thru. Also depending on which springs you have in the TQ you will have to go to probably the 3 or four inch and not the orange which is rated at 5 inches which may cause your rods to lift up some at idle and then will be bypassing the idle circuts. So drilling the plates is the most likely thing to do but your not doing anything to the fuel thing just the air thing. Does any if this make sense? And by the way, I have a 94 Chrysler Power magazine that has an article on Big Cam Blues. If I could post this entire article I would, it is very helpfull!



The tree is not the problem it is not bouncing at idle, but anyways I dont quite think this is right. Idle circuits are Idle circuits. You maybe right about them not pulling enough fuel or air but changing the rods, springs, or main jets will not effect the idle circuit because there is no air flow pulling fuel through the main circuits and boosters. Kinda like a holley's PV circuit is active during idle but since no fuel is being pulled through the boosters it doesn't change the idle circuit richness (but as soon when fuel starts flowing through the boosters all that changes.)

I can idle, I just need some MORE idle rpms without exposing more of the transfer slots.

I'm not trying to be difficult, it comes naturally....
