UTG 727 destruction

I’ve heard and read for years about how durable the Mopar transmissions are but I also see stuff like this.
How come I don’t hear about dudes that barf the transmission in their Chevelle or Fairlane?
What is mechanically different that leads to this?
I did burnouts all the time in several Mopars with and without Sure Grip diffs. I never had one fail from that. I’ve had them lose reverse or third gear, I’ve had them just give up and fail completely but never break anything like this.
Nor have I, but I burned-up a bunch of low/reverse bands manual shifting 1st-2nd, but then all of My higher powered rides were 4-gears. If You watched Cope's video, He explains how GMs can grenade on the top end, if You're not careful.
One night at Keystone, the '73 Satellite I put a 440 in for a guy, popped the rear u-joint....the original flash-bang...on a post-burnout dry-hop. Luckily He was letting off just as it went, so it didn't grenade, but We just replaced the whole thing. The DC/MP racing manuals warn You of this potential with exclamations for good reason. If You pop a rear/joint/axle/sprag etc., even if it didn't blow, it must be inspected/repaired or it may blow on the next romp.
