Torque-converter stall speeds

I'm about ready to search for that roller cam for my long awaited build and I had a thought about the factory stall speeds used in J10s with 401s. I was thinking it might be around 1500-1800rpm but not quite sure as it has been awhile since I drove the truck. Lost that feel so to speak.

Saw some new rollers on e-bay but the measurements I'm looking for were well below my wants, and the next bigger cam are way over which needs a 2500rpm stall.

I want to keep the stock converter and was just wonderig how close I can push the limit.
