4 speed at the track - tips?

With the 4 speed you need to watch that you don't roll thru beams. I raced a stock 340 Challenger w 4 spd for a while and this helped. The disc brakes will retract slow most times so hold your foot on brake hard until you are both staged. Then you can let off brake pedal and onto gas to starting rpm while yellow lights count down. Practice this at home or road before the track to see if it rolls. It is hard to hold brake and toe the gas to specific rpm at same time. good luck and have fun
