Hmmmm.....how about side steppin?
The art of speed shifting.....plus slipping your foot off the side of the clutch peddle to shave some time off a shift!
I remember as a kid doing that in a 66' Impala 2 door coupe,327/275 hp
three on the tree.
I was pretty sucsessful for quite a while,till'....my foot was quicker than my hand,and first and second gear climbed on top of each other......and broke my (well...mom and dads) transmission case all up!
