How much foot pounds of torque can stock block and drivetrain take?

Torque is what puts the most strain on the parts. All horsepower is, is just a jacked up measure created by James Watt to help him sell some motors. Power is just the rate at which work is being done. Torque on the other hand is a measure of the rotating force on an object. Torque breaks ****. lol
I wouldnt push the stock shortblock on my car for extended periods of time over 400ish ftlbs personally. For nitrous, i wouldnt worry about it. People have hundreds of passes on their cars with no ill effect. A blower, thats a different story though.

My stock t45 is holding up pretty good, shifts like butter still with 145k on the block (don't know if it was replaced before I bought the car[had 118k at purchase]) Bladerunner once again made a wetarded comment add him to your ignore list.

400-420 rwhp is the limit for the stock shortblock from what I have seen
any more than that and you will be on barrowed time even with a good tune.
Any power adder is a risk running on the stock shortblock.My friend bent
three of his stock rods only running 8 psi. of boost from his blower.
Do it right the first time and start with a built shortblock with forged internals
before you install any power adder.

HOSS makes a good point... a lot of numbers are thrown around without any real understanding of what they actually mean. TQ is just a function of HP at a given rpm. If your motor produces its 400rwhp at 3000rpm instead of 4400rpm, you are making A LOT MORE TORQUE. So generalizations like not more than 400rwhp is a little deceiving. PURP also makes a good point regarding what means of producing the power is used. A blower is adding stress much of the time while nitrous is adding stress for only very short durations.
I think your conscience is the main guide here. How much risk are you willing to assume? If it is low, you need to remain relatively conservative in your output. Some guys are willing to roll the dice and get away with more agressive set-ups, but some don't.
My gut from all that I have read and discussed is low 400's HP is around the transition point for risk, and torque from spray can go as high as upper 400's. Beyond those points, lots of other factors come into play and it is a crap shoot.
GOOD LUCK with whatever you decide to do!!!

That depends, but if it's tuned on the conservative side then probably not. My buddy did the same thing last year. Went from a 100 to 125 shot without changing the tune and was fine.

Ultimately.... 'tis grip that breaks parts on your car!
All the torque in the world will cause little strain without the grip to create the forces necessary to damage stuff.
I say... run 800 pount-foot and a set of Sumi's
