You can change the amount of pedal travel (making it greater) by moving the attachment point on the arm in the firewall down towards the pivot. I can't see real well but ideally your arm on the firewall should be leaning forward a little less than 45 degrees with your foot off the pedal. That gives finer control at low to medium throttle but once you are stepping on it it moves quicker. It looks like if you shorten the rod from the bellcrank to the carb it will move the arm forward, lifting the pedal off the floor.

Thanks Ross, changing the position on the bell crank closer to the piviot point would help the travel for sure but changing the linkage arm would only bring the pedal height up at zero throttle not changing the travel length though. What is normal/acceptable travel on these trucks?

How far does the pedal travel in your daily driver? That will give you an idea of what you're used to and what it should be. You can adjust the length of the bellcrank, or the attachment point of the carb linkage rod on the bellcrank accordingly.

Agree with Wayne, make it something that feels right to you.

I have a lokar set up on mine and it works great. I got the hanging pedal and the cable and the carb linkage, return spring assembly all from lokar. It's clean and has good pedal control. IMHO that's what you should do. It's really not funny when the linkage gets stuck and you can't stop. Not worth the risk. Think of the money spent as insurance.

Thanks for your concern Zoot, but I think this setup should work fine as it is smooth in operation as long as I get a stronger return spring to assist my lead foot! If not then the Lokar is a solution.
