Will GM 200r4 work with factory floor shift location?

Lock-up negates stall, you could have a 4500 converter and if you lock-up at 1800, that's your cruise stall. 1800. No slip, no drips, no dips. Wired to a toggle switch, or programmed into a fancy vacuum switch or computer, whenever you want it. That's why all these homeboys with newer camaros and mustangs get away with hi-stall drag action, and cruise home like nothing happened.
