Dumb question about what the big boys do at the strip. Don't laugh. Be a good person and take pity instead.
Backstory: '62 Valiant with a pretty hot 408 stabbed into it. The cam has about 246 degrees of duration at .050 and it's got cast iron, open-chamber "J" heads that have been ported about as much as possible. I built the engine back when higher-octane gas was available at the pump, so we didn't have to worry about quench. (Or maybe it was because we didn't understand quench.) Now I have to run it on a mix of 91 octane pump gas and VP Racing 110 octane, but that's not the problem.
This engine really comes on strong only around 3,000 or 3,500 RPM, so I want to keep the RPMs high.
I believe I have my Bouchillon Performance 3350 kickdown assembly working correctly, and I am happy with it. But when I adjust the kickdown cable so the 727 shifts automatically at a nice, high RPM, the car does go quite well but the cable is so tight that it's pretty hard to press the gas pedal. So, first of all, does that seem normal, or am I doing something wrong?
And when I go to the strip, should I adjust the kickdown cable so it is more loose, will automatically shift at a lower RPM, it will be easier to push the go pedal, and just shift it myself with the pushbuttons instead?
