I've broken a few differentials too. One of them was behind a 283 with an automatic... Another was behind a 4-speed and yet another was a 2-speed rear under a F700 Ford so it doesn't even count.
I've broken a couple of transmissions too, one of them a very expensive 5-speed. That was a very sad day. It cost more than $1000 to replace back when that was a lot of money and more than I'd paid for any car or truck I had owned up till then.
And I've also broken drive shafts and output shafts but that was on four-wheel-drives.
All of this happened more than 30 years ago when I was an innocent kid. Now days I have much more grey hair and tend to be more cautious about how I build things and how I treat them.
Sure 500 horse in most pickups is just going to smoke the tires. But when it does hook up watch out for flying parts!
I once picked up some twisted metal laying on the floor of a friend's shop. It was the drive shaft out of an El Camino. I had sold him the 396 that pretzelled that driveshaft and broke both the transmission and the rear. To do that it had to break the rear first.
I'm sure he will be fine with the Jag, but I'm not going to tell him it can't be broken because I don't believe it.
