Don't understand cam specs or stalls at all. How much does the th350 converter stall compared to a th400. The trans builder told me to use the th350 converter in my th400 for less fluid usage and slightly more stall. Can you explain what my cam is and how the stall would help?

Is going from a 3.07 to a 3.42 rear ratio a big change? It doesn't sound like much as compared to changing from a 3.07 to a 3.73.
