My 67 RS hesitates for about 1 second when I take off from a stop and press the gas pedal ~1/4 inch. If I hold the gas pedal in that position and the transmission shifts from 1-2 I get the same hesitation for a second again.
My setup is a 327, 9.6:1cr, vortec heads, edel performer intake, edel 1406 600 cfm carb, MSD dist w/vac adv, MSD 6A, new MSD wires, A/C plugs, CompCam H268, 350 turbo, 2.73 rear. I've replaced the carb, replaced the exhaust, played with the timing, vac adv porting, metering rods, and idle mixture. I'm really stuck on what it could be. Please help!
If I set the idle mixture on the rich side the problems is not so bad.
