cooling
#2
I have heard that it would be unnoticed, but in theory it doesn't cool as good I guess. I've looked into getting pullies, but even my brother with a 500+ hp 306 ci mustang said don't bother. I guess they really only work well in road race applications with alot of high rpm driving. Oh well, ya love em or hate em, but cooling inefficiencies, I wouldn't worry, the f150's cool pretty good on their own so you'll be OK.
