Anytime you get wheel hop or the rear tires bouncing while on the throttle it can be a problem. You are constantly loading and unloading the half shaft. I put in a set of 3 inch half shafts with solid ujoints from a supplier. They have been pretty bullit proof and I have about the same HP and setup as you.
Those from Ecklers are similar to mine but I paid about that price for 2 of them. This was a few years ago but that seems a little steep on price.

You need to do some work on the rear suspension to make it more stable. With the amount of money you have already invested in the engine, a little more to put that power to the road smoothly will be worth the expense. Besides, you're spending more than you planned for half-shafts. It would be a good idea to buy some stronger shafts/end yokes, and maybe some safety straps around those shafts.

VB&p makes a single mount traction bar that mounts under the center of your rear spring. Highly effective at eliminating wheel hop. Make sure you use solid spicer U joints with no zirks. The 3" halfshafts will work much better than the stockers.
Clutch finesse will be important. but eliminating wheel hop will go along ways in reducing breakage.

That would make a great poster on the wall of my shop! A undercarriage we would all love to see when looking at our vettes!
Just fantastic! Wow does not do it justice in the least.
Thanks for posting that pic.
