Any experience good or bad with clutch fans on your mopar?

Other than dog-eared blades & signs of impact/damage, it's difficult to tell just looking at them, even spinning them can be less than conclusive. Some fans have the blades
intentionally "staggered" a tad, so You need to be tuned into Your engine before & after You install any used fan for any new/unusual vibrations.

EDIT: And to back up what QuickDart360 and inertia mentioned, the fan & shroud
work together, the shroud should engage the blades 1/3 to 1/2 of their sweep, &
this won't be a problem for A-body guys....but the fan should ideally have the
blades 3/4-1 1/2" from the cores. Now on a '73 Charger..............lol!
