Torque Converter Questionnaire/Laundry List

You must ask yourself the questions

How do you want the car to respond to the engine you built.

If you want the car to perform. The converter should brake stall at the operating RPM's of the cam you selected. I ran a 5500 tight with a 686 roller on the street. Worked great, I would never go anything lower then a 3500 for any performance application.

These cars stalled at around 3000 from the factory in 340 cars. All cars that come here for engines for the street get 3500's. Race motors 4500 -5500.

Ask anyone that owned a 4 speed car at what RPM did the launch their car from a dead stop for the best performance with a stock engine. Usually it was 3000.
