I leave at 4000 on mine and have the best R/T at that..........

Stall speed will change your R/Ts but every car is different, my bracket car changes about .010 for every 200 rpm change. There are some different ways to change your R/Ts if the stall speed dont work for you or your car. You can adjust front and rear tire pressures or adjust the travel in your front end, if you tighten your front up it will make your R/Ts quicker but you will be more likely to have traction problems. Its all in finding what works for you and your car.

1100 # of brake pressure, 3400 in the stutter box, gas pedal on the floor, will go.020 to red. short time is 1.48 to 1.55 with a old old 4500 rpm 8" A-1 torque converter and a 2.78 low gear C-4, 5.14 gear and 29X9 Hoosier's car weighs 3520 with me in it.

i have tried with the two step and just foot break and two step off the brake with the box set at 3200,now turn it up and you use more brake presure and it turns into an elastic band ,the converter will not act the same ,you lose the flash of the converter ,you have to wait and see alot of yellow to be green,,but foot braking you almost have to leave at the hint of yellow to cut a .030 light, i have data logger and the two step is real consisntant on rpm to where the gas and go has a real jagged line and the converter hits way different between the to approches ,,,if you have a real tight converter you will not have a choice the foot brake ,you cant two step the motor to low or it will pop thru the intake ,,,,,if you run a holley foot braking is the way to go you can tune those to any weather condition but stocker carbs can be tempermental gmonde

Hey guys,
This weekend I had a chance to try it out again..I found as stated by gmonde that when you shallow and stage at a higher rpm you need to leave at a hint of yellow to cut a good light. I cut a .560 (we use a sportsman tree) but broke out anyways....You have to have a aggressive mentality when your doing this. For those who played football it is like you are on the defensive line watching the center snap the the ball and exploding onto the o-line..
