Underdrive Pullies

[71Duster]

Looking at the march high water flow v-belt pulleys. Has anyone run them? Thinking of trying a set on my 440 for better cooling and fan speed in traffic.

Brain fart when making the title. Meant to say overdrive pulleys

Underdrive is opposite of what you want for better cooling..
