I remember those days very well, 40+ lb. flywheels and no RPM limiters, 5.57 to 6.17 rear gears ratio with a 3.25 1st gear ratio and foot on the floor launches when the first yellow (4 yellows back then) came on and then let go of the clutch pedal when the last yellow just started to glow
Oh baby, what memories
I remember seeing Rehr and Morrison 2nd gen Corvette with Lee Shepard (RIP) driving it at the 1971 or 1972 Winternationals (SP?) in either Modified Eliminator or maybe in one of the old gas classes that ran back then. He would shift that car out of low gear with the rear of the car besides the Christmas tree and be in high gear around 400 ft. from the starting line, screaming SB Chevys had a distinct exhaust sound even back then, make you want to stand back in case of flying debris occurred
