Foot brake drag racing

We don't have a track anywhere close to us in the Corpus Christi Tx area. so that is out. The only track even remotely close to us is Edinberg TX (3 hours South ) where the land is now owned by the city of Edinberg and race schedules are sketchy to none.... One such incident was where a Test N tune day was scheduled only to be shut down by someone on the city council after racers had made the 4 hour tow to the track. Thats how sketchy ....Enough on that

Foot braking to me is knowing your equipment. Knowing what RPM to launch at without the car creeping, Having your braking system set up correctly, Having tire pressures set up optimally, Knowing and practicing over n over n over again getting your 60 foot times to optimum.................

I really think I need to do some reading on techniques etc... Technical articles etc....... as I built my 72 Duster trying to recreate a 1972 Super Stocker where 90% of the cars were 4 speed....(Mine is a pro built automatic 727) as I watch old drag racing videos etc.... Ronnie Sox amongst many others would rock their car into the beams as I am guessing here but they did have a line lock to keep the car still until clutch dump time.
I am not sure but don't think you can even have a line lock in a rea competition series like they run at Bristol each year
I may not have the optimum set up in my car to begin with as Set up is everything Just as you are describing!
