I have a 440 stroked to 505, and i put a barry grant six shooter on top instead of the holley's. Since doing this the accelerator pedal has been very touch to use. It seems somewhat stiff. I know the linkage is based off of a GM, but i modified my mopar stuff to make it work. The set up has been out for a bit now and just wondering if anyone experiences same problem or a way around it. Anything to help. THanks.
