I'm Awesome
There is another fan in GMs parts bin that moves a ton of air. GM put them first on the TBI 454s, then on the CPI Astro vans and later on the 8.1s. Its a nice upgrade from the little 5 bladed fly swatter as well. It is the size and pitch of the 5 blades that make it pull more air. It fits the standard 3.25" bolt circle of a standard reverse rotation fan clutch.
