first time ever on track

411 maybe a little too much of a jump for what you`ve got there. If you don`t build your engine then I wouldn`t raise the gear ratio too much. A 3.55 or 3.73 would be a good choice. Your car sounds like it`s right where it should be for it`s build (it`s a stocker isn`t it?) and with you being a novice at the track. I`m certain your car will go 13.80`s with nothing but practice. I had a stock 68 340 A/T with a 3:55 that would run 13.80`s consistently. It is very addicting when you get the chance to run the cars wide open under measured and controlled circumstances. Congratulations on your new found love! :toothy10:
