Why Aren't There More Drift Camaros?

As cheap and as common F-Body Camaros are, why aren't there more of them in drifting?

I can see why it makes sense to start out with a Nissan S-Chassis, since chances are that's what everyone else at your local drift meet runs.

But why is it that there are so few of these rear-drive V8 musclemobiles going sideways?
