I gotta 71 Mach 1 with a 351C 2V inside. I replaced the intake manifold with an Edelbrock Performer intake and slapped an Edelbrock Thunder AVS 650 on top of it. My problems are that the engine will idle fine, but when I adjust the fuel/air screws I get no RPM increase or decrease when adjusting the left one(passenger side). Only changes when adjusting the right screw(driver's side). When I put the car in gear, she stalls and starts to backfire. I've searched for vacuum leaks, but so far I haven't found any. I move all the old vacuum plumbing over from the Cleveland intake. When I had it on the road after the swap, the engine would sputter, surge, and stall. When I open the throttle, I get a high pitched squeal, and I've checked for belts slipping. Is this all related? The reason I switched everything over, I was tired of rebuilding the autolite 2100 every time the car sat for an extended period. Any points in the right direction will be greatly appreciated.
