Default Should it handle this

Hi, I have a 2000 Z28, stock engine with headers, under drive pulley and tuned. The 10 bolt has been rebuilt with 3:73 gears, girdle, cap studs and axle tubes welded and solid pinion spacer. Full weight it runs 11.7x @ 113 with 1.57 69fts. The rear whines loud after one trip to the track. Is this too much for the stock rear or was it probably put together wrong? It was having a slight whine before the track day so I’m not sure if something was wrong before. Any thoughts?

Stick or Auto? If stick it's on borrowed time, if Auto it SHOULD hold.

The car is an auto with a 4,000 stall. I think the rear end should hold up to a stock engine stalled auto so I’m debating on having someone else put another set of gears in it and trying again?

Re-torque the pinion bolt? Maybe a good launch seated the bearing race harder than the 10 ton press they used to assemble the thing.
