Turning torque for engine

In the other post, there is a diagram of the kit. It shows the pump turning clockwise. Coolant flow, as an example, my motor makes more heat than yours. I run the March underdrive crank pulley and a stock A/C water pump pulley, through a stock 340 radiator. They are pretty close to 1:1. So I would be pretty confident if your crank and water pump were close to 1:1. IIRC the March “performance” pulley kits are under driven. My crank pulley is between 5-6”. If your pulleys are the same size or close. You should be in the window on coolant flow. This is an auto right? Check the trans fluid, is it burnt?
