Tame my 4-speed Stroker....

The T/A has numerous times.
It doesn’t go any quicker because leaving higher changes the dynamic of how the motor gets loaded.
The factory trans aren’t geared optimally for high rpm launches with high traction.
Something has to give(tires or clutch), or it breaks.
When you put sticky tires on it, and leave high...... and it hooks......it bogs.

I understand what it takes to get a stick car to “work”.

100% FACT. Something has to give, or you **** parts out faster than you can replace them.

More RPM at launch isn't always better. Especially with something like a Pontiac. Or something making a big load of torque. Unless you can get way past peak torque when the two step comes off.

The clutch can't be abusing the tire. RPM, rotational inertia (like heavy flywheels) and an aggressive clutch will beat the tire to death, break parts and go slow if you can make it live.

Just some random thoughts from a life long bench racer.
