I raced an Olds with a 455/th400 and put many passes on the stock driveshaft that had a rubber slip connection close to the rear u-joint. Genius that I am, I figured that a solid shaft would be this huge improvement. On the first pass at 100+ it roused me out of my slumber by reconfiguring the floor contours. Found half of the shaft and the slip yoke was still in the back of the trans. The bellhousing was busted almost all the way around, plus lots more damage.
So, my wager would be the driveshaft failed for whatever reason. I don't think TH 400's have a reputation for weak bellhousings.

BTW, for Olds freaks, that was a "W" code tagged trans.
