Quoteprobaly something like 2000-4000 over.

:wary 4000 over stock would put you at redline. Do as soulcontroller recommends and get a 3000 stall torque converter from ERT. If you need a monster-ass converter, PM me and I'll see what I can do. 3000 is plenty for a street car though, and the ERT converter is of nice quality.
