I have a 70 Charger with a mild freshly rebuilt 383. i cant tell you the specs of the cam but its mild. its 9.5:1 compression with headers an edelbrock performer rpm intake and a 750 street demon. the problem i am having is the thing is a dog off the line. it hesitates and bogs down. and if i get up on the stall then let off the brake and gas it, the rpms drop some and it launches like im launching from an idle. once it gets going its alright but i feel like something isnt right i know there is more potential in this motor. also i can never get this thing to break traction ever. ive checked the timing and its at 12 btdc w/o the vacuum advance. could it be the carb? to little or to much fuel?
thanks for the input
