Will GM 200r4 work with factory floor shift location?

If you get a quality cut-to-fit converter, you can cruise well below the rated stall speed. I have a 3500 stall 9.5" non-lock, and it cruises nice and cool at 2100. Shorter gears in back help out too.

Don't loose any sleep over it, I asked the converter manufacturer directly and they weren't worried at all. I paid $515 shipped. Very happy.
