Run electric fans all the time?

But 0.95 is the standard non-a/c pulley ratio (i.e. 5% underdrive) for big-blocks with the eight-vane pump. Which is what I had, and also in agreement with the chart you posted earlier.

There is no 1:1 unless I get some custom pulley setup. Will it be worth it for 5%? I'll be shifting at well over 6000 rpm and don't want the pump to cavitate, either.

The Flowkooler 16-fin pump just arrived and it's a nice looking piece. It should move a lot more water than the standard pump that came out. I'll pop that in tomorrow and see how my temps do (with the fans back in).
