March performance vs cvf pulleys on 340

25 percent underdrive power steering, which is doable. But I generally don't like under driven water pump pulleys and will be the last person to try to convince you that it's a good idea.

thank you for your honesty, so my crank needs to be at least a 6-1/2 to match the water pump pulley at a 6-1/2 as well to keep it 1:1 which i agree makes a lot more sense not to stress the cooling system.
