your convertor stalls around 2800, not 2000. not sure where you found that number at. probably from the torque numbers shows "at" that rpm speed. but, thats not "the" stall speed.

just throw some headers on it, a good cam (like a hughes whiplash) and remove the computer and throttle body for a carb. my warmed over 340 is going into mine, when i get home in a week.
