Thought I would get this out here since it is a pretty easy upgrade and only takes about 20 minutes. The direct drive fan works great for cooling but isn't exactly performance friendly. Upgrading to a modern thermostatic clutch fan will net a few easy horsepower and quiet down the engine a little bit also.
Also it gets the fan a little further into the shroud which IMO makes it less of a danger to fingers working in the engine bay. Direct drive fans hurt......
Parts I used are below.
Derale 17" 6 Blade Fan #17117

Hayden Fan Clutch #2710
http://www.summitracing.com/parts/hda-2710
4 Fine Thread 5/16x1" Bolts to bolt the clutch to the water pump
4 Course Thread 5/16x3/4" Bolts to bolt the fan to the clutch
8 5/16 Lock Washers
Installation is easy take off the old fan and spacer. Bolt the new fan to the clutch paying attention to which is front and back. The fan will be labeled either saying what side is front or what side faces the engine. A bushing is included with the hayden fan clutch the needs to be installed to center the clutch properly on the water pump. Slide the new fan setup into place and bolt it on. Below are pictures to show that the new fan setup sets just a smidge farther into the shroud but just about the 50/50 in and out which is generally considered the desired spot for a fan.
