gear ratios and torque

crackedback said

Stall is NOT a static number. A company can claim a TC stalls at 2500. Put that same converter behind a 400" 4" arm (500#/ft)and a 273" (325#/ft) stock stroke engine. Is the converter going to stall the same? Nope... 273 will stall lower.

Same with changing rear gear. 3.23's put more load, same as the 4" arm engine, on the TC.

Ok, still confused. I get that the converter may stall at a different speed depending on how much torque the engine is throwing at it. But say you have a 2500 stall converter, once you've met, or surpassed the stall speed rpm, isn't the lower gear going to give you faster acceleration at that point? Or are you saying that because the converter has less load on it,(because of the lower gears), that it will continue to slip more all the way down the track? I know that there is always a certain amount of slippage going on in a non lockup converter.
