Looking for info on the 440 4BBL Torque Converters

I found this chart on the web

Factory Converters

Engine ................ Diameter ............. Stall-Rate
* 225 ...................... 10.75" ................ 1450 to 1650
* 273 ...................... 10.75" ................ 1800
* 318 ...................... 10.75" ................ 1750 to 1950
* 340 ...................... 10.75" ................ 2250 to 2450
* 383 {2-Barrel} ...... 11.75" ................ 1850 to 2150
* 383 {4-Barrel} ...... 10.75" ................ 2350 to 2650
* 440 {4-Barrel} ...... 11.75" ................ 2000 to 2350
* 426 {Street Hemi} . 10.75" ................ 2650 to 2850

I'm putting in a fresh 727 on my externally balanced 383, with stealth 440 heads, purple cam,
edlebrock performer intake, 750 street demon carb.
Since my flex plate is the larger 11.75" and I like the stall rate on the 440 4 barrel, would anyone have a source for factory spec torque converters or part numbers?
