Small case diff. strength

[02stu]

How much power can a small case 4.10 hold? What happens when they fail do they just burn out the clutch packs?
Thanks

According to Metric Mechanic they can tke 220 lb.ft. of torque.

So, in theory, you could use it with a stock m20? I've always heard an m20 will tear up a small case in short order. So, what's the scoop?

I've been running a small case 3.9 diff (rated 240 lb.ft) with 2.5 M20 (headers and Jim C. chip) for a few years. It didn't tear up in short order.
