Impossible to achieve high 1.20s sixties

Set the car in the lights with the line loc. If the car is rolling that is not helping you at all. Sounds like you are sledgehammering the clutch on the leave and the gearshift. a stickshift normally doesn't 60ft like an automatic no matter what you do. Our ET picks up after the 330 on. Looks like your shifting that car 5 ft before the 60 ft clock. You may have a little to much 1st gear in it to acomplish what you are looking to do. What ET are you running? what kind of 8th time and MPH are you running. That car looks like fun to drive.
