Natalie,

I fought this with my single 4-barrel on my 427 when I first put my car on the road, and never really round the culprit, though it had to have been carb tuning because the day I installed the 2x4 carbs its stopped doing it. Now, I can let the clutch out and the car will pull itself down the street without bucking in 1st gear at 850 idle rpms with no pedal input.

FWIW...

Jim
