They should have all of the info on the ideal situation it was designed for to determine how close youre proposed setup matches or if they've got another cam that may better suit your needs.

 

Contact a torque converter manufacturer with your cam, engine, tire and final gear spec's. ACC " Boss Hog" is very friendly and provides answers for free over the phone. Usually whatever the cam RPM range is about what the stall would be, guessing a 3000-6500 camshaft would need around a 3000 stall. Good luck

 

Call ATI. Best converters around. That's a pretty mild stick., You won't need a lot of stall.
