Haven't had a chance to put it on, but I don't see how this won't help. Everybody said use a 7 blade fan and clutch from a early to mid eighties k30 454 crewcab w/4.56's. Well, My dealer was unable to find a listing that included the 4.56's so here is was I got.
GM part # 15963247
List price is 156.35
, but I only paid about half that (it's good to know people)
. Was a k30 crewcab w/454 auto a/c and heavy duty cooling. No luck on the 7 blade fan, has been superceeded by the 5 blade. So I'll just run my 5 blade till I come across one.
Here's the pics comparing old clutch (Stock 87 clutch) to the new clutch:
