This is a setup ive used on a 1/2 filled small block with 4:88 gears on the street.

Dual HD spal fans with a dual pass cross flow rad and cover that also lets air move.

Ive one fan hooked to a T stat in the intake and the second fan on a toggle.

Ive never had to use the second fan unless I want a rapid cool off before I shut it down.

I got the paperwork on the specs if youd like them.
