But the question remains: how much horse/torque will the stock half-shafts
(appropriately modded) take? 

>>>More than you'll ever put out.  But if your driveshafts are indeed trashed, then you need to start from scratch.  You may find it just as cost-effective to buy heavy-duty Spicer units instead of buying rebuilt stockers.

Dennis Quella tells me that some of the Pikes Peak racers he builds gearboxes for use Pantera driveshafts.  In the course of the event, they actually TWIST like a pretzel without breaking.  At some point, they remove them, swap 'em around, and continue running them, which then causes them to UN-twist....

As long as the U-joints are good, stock driveshafts are fine.  But since you said that yours have been machined to the point of destruction, I wouldn't plan on using them.
