Stock stall speed is 1800-1900RPM on the LS-1
F-body torque converter.

Any degradation of engine output will make your
effective foot-stall RPM lower.

But we don't know what was normal, "before",
for this car. It doesn't sound like anything
unusual for a stock vehicle, offhand.

How often do you power brake...?

Possibly may have broken something or bent the TC fins; the TC is loading your engine down and not letting it rev higher (assuming your engine is not suffering from power loss).

If your TC is stock, you most definitely did not stall the 'verter up to 5000rpms unless it has a major mechanical problem.
