Does your truck have a long or short water pump. My chevelle has a short and from what I have seen there is no HD version . I went from a stock clutch fan to a 7 blade direct drive. Still ran hot. I put a DeWitt HP series in with dual electric spall fans . Car can idle indefinitely in 95° weather. Used to heat up coming off highway speed it does climp a little but the fans kick in and it goes right down to 185.
I'm running a mark Jones 467 .
