Slant 6 torque converter stall speed

[440DART1970]

Does anyone happen to know with the 1970 slant 6 stall speed would be on a transmission converter for an automatic??

Generally 100RPM higher than a 318, however, behind a 318(or bigger) it will stall even higher. Old chart I have shows 1800-2100RPM, depending on condition/tune etc........
