TH350 trans usually break the roller clutch on the direct drum that splines to the 2nd gear clutch. And the part you show should have never been in a race transmission, it is replaced by a lug that locks the low roller to the case. I built a lot of TH350's for mud racers in jeeps, they held up real well until they started going over 600hp
I expect this thing was substantially more than that. It was pretty stout. The John Force burnout likely didn't help it.
The track people could only stand out there about 300' looking at the guy laying in the middle of the track. The local ambulance crew/medics had recently stopped coming to be on hand at the track. Seems the track operator got mad about the number of free hot dogs they were eating and cut them off. So they stopped showing up.
This was some years ago before everyone had a phone in their pocket or the phones would even work out in the sticks. I'll never forget, the track announcer gets on the PA and says "Attention in the concession stand. Dial 911"
Me and the guys I was with were like

Easily top 3 cluster I've seen at the track.
Moral of the story. Put the right stuff in your car so no one has to see you roll around on the track, take you to the hospital and/or clean up the mess.
