Built 273, what sure grip ratio with a A833 3.09 first gear

Huh tgats crazy low, is he even using tge clutch or is he powershifting or what? I dont have the balls to do that in mine lol, way too expensive to fix a mistake, especially without a rev limiter one missed shift and you are done
Believe it's a lenco 4 speed , just use the clutch once to get it moving and then shift straight back and forth pattern , gas pedal to the floor . Yeah !!!!!!!!!!
