What stall speed to use?

[jayoldschool]

There will be no 1/4-mile runs and mostly around-town driving; maybe 1 @ 150-mile trip a year. Engine is stock 96-97(?) 5.7 vortec with 4bbl intake and carb and headers. And I DO use the lockup, planning to do the same w/new tranny as present one:locks up when it shifts into overdrive, yet I have a lockout switch run under dash to completely bypass the lock-up when I desire.

Lowest stall, stock converter you can find. I would suggest one from a Caprice/Roadmaster/Fleetwood. 1800ish.
