RockinRiviDad, you are truly ROCKIN! This is the answer I have been searching for. I just had a Holley Sniper installed on my '64 Rivi with a 425. Right off the bat, the gas pedal was trash. It barely moved and was all or nothing when I got it back. In the interest of not paying someone else to tinker with it, I took it home and have been trying various modifications over the last week. The first problem, as you pointed out, was that there was no travel in the pedal. Even with the throttle arm threaded all the way in, I had to put deeper bends into the stock arm to shorten it. Once there was more play, I tried various spring setups to increase tension as the accelerator was pushed. This helped tremendously and allowed me to control the acceleration at slow speeds. But it still goes WOT when trying to accelerate quickly. I similarly concurred that it was the location of the throttle arm attachment on the Sniper linkage. It should attach at a point allowing for linear movement of the linkage. But the stock attachment point on the linkage is slightly lower than horizontal in the range of motion causing it to jump once it reaches horizontal. This bracket setup appears to correct that and I'm planning to fabricate one next week.
My one question is: Why did you modify it by welding in the tab that moves the throttle arm attachment point closer to the Sniper? It looks like the stock bracket would work just fine as is and the throttle arm has tons of side to side play in it. Was there a clearance issue or a conflict with the kickdown setup?
Your posts and additional feedback are greatly appreciated!
