Throttle cable/gas pedal issues - holley on a 318

Ran into same here too. I am getting the holley adapter from Mancini or summit or jegs. It's all about price with me. Retiree Budget. I am sure tha "little extra" prob.' will be the carpet. I've already figured and solved problem with Isosceles style pedal shim's. Being able t do it correctly now is reassuring. Thanks for you're post's being there for when I needed it. I had this thing tuned to 8.81's in the eighth on 60% throttle use. Can't wait for this! Later, DartMan.
