If this is a dedicated race car you could do what I did. I changed the gas pedal and used a solid rod (like the old GM products) to the carb. I went from .05-.07 reaction to .001! I felt there was a lot of resistance in the factory cable. I used a Chevy truck pedal but since I got an e-body, that pedal could be made to work also. I was very surprised how well it worked.
