I have an rebuilt sbc 305 vortec, with an Holley 600 VA. It originally was tbi (if it helps) but now carborated with an hei distributor instead of point distributor and a stock cam.

the problem im having is the stalling! at idle it has a light backfire on the 2,4,6,8 side of the motor. i went over and changed the plugs and it smooth the idle a bit but it still stalls when i put it in gear :confused:

im open to every suggestions avalible
