I do not think I would. I do not think that lock-up clutch was designed to take that kind of abuse.
Why do you want to lock it up? Are you running out of RPM?
I have seen that others ET better leaving the converter unlocked.

I stall my TCI4000 to 1800 when I am looking for consistent runs like in bracket racing.
When I am going all out I will stall it to 2500 -3000 which usually gets me the best 60’ time.
60’ when stalled to 1800 ~1.55
60’ when stalled to 2500-3000 ~ 1.50-1.51
My old Yank 4400 liked to be stalled the same way.

1.71 is a good 60' but it should be better. What tires are you running? What are your mods? What is your race weight?

Our PT4200 likes to be loaded up to a point taht it just keeps from pushing the car through the beams and then hammered hard off the line.
Your results will vary. We are getting 1.42-1.43 60fts when it hooks solid. I would expect 1.48-1.52s depending on traction and your power level. That reduced 60ft will provide better ETs, ususally 2:1 on our car.
Good luck!!
