7 Blade Fan with Clutch Slant 6

In a car there is not enough room for a clutch. I am running a 7 blade fan in both the 66 and the 73 slant darts with no problems. In my slant powered 69 D100 I am running a V8 7 blade fan with a clutch due to a crapload of room. The truck came with one of those crappy flex fans that like to come apart, that was the first thing I took out!
