Hey all, Just want to say quickly Great site. I refer to this very often. I am building a 72 shorty 2wd, 355ci, 700R, everyday driver. I am not real sure on what tooth gear I am needing to run in order to show right on my speedometer. Any help would be greatly appreciated. Also on the TV cable, I am running a holly 4160 carb with the correct holly throttle and TV bracket, and geomtry corrector that bolts on to the carb. Setting my tv cable seems to be a little difficult. Any one have the same issue? Thanks again for any insight.
