It also needs a mod to the Clutch pushrod.
At the end of the Drag strip the clutch pressure plate is being loaded by the lockup clutch and the push rod must overcome the pressure of the lockup clutch. It normally only has to overcome the spring pressure.
There is a chance that the pushrod "mushroom" may try and weld itself to the clutch pressure plate.
Because it has so much more pressure to overcome.
To prevent that ever happening this is what we did.
We made a new "mushroom" that could hold a small thrust bearing on it's end. This bearing will press against the pressure plate and take the extra weight with out trying to burnout or overheat the pressure plate
