the subject is my question? is there anyway to find out if its stock or has been replaced?

 

wow wrong board my bad. sry

 

hold the brake for all your worth and slowly press on the gas. you will feel the rear end load up and actually raise up some. when the tires start to barely spin over that is the limit of your stall. at your limit is what stall speed you have. if your stall is stock i would say 1600 to 1800 max rpm.

 

thanks alot!

 

ok so call me dumb but i want to learn, what does the higher RPM stall do for you. i'm very interested in this and have never asked but now i am so all help is appreciated!

 

most stock 700 convertors are rated @ 1397 RPM.

 

A higher stall speed will allow the car to launch at a higher rpm, As opposed to taking off at an idle. Gets you rolling quicker, helps get the engine in the power band. Did that meake any sense? Sorry I'm going to bed.

 

yes makes lots of sense, and come to think of it i think i have heard that before. but thank you.

 

That's the limit of your brakes, not the actual "stall" speed.

Put the park brake on first, that may help hold the car. Or, put it up against a curb and try it (just make sure you don't jump the curb).

Higher stall allows the engine to get into its powerband. If it is already in its powerband with the converter you have, higher stall wouldn't be beneficial.

There is also a "torque multiplication" aspect of higher-stalling converters, but I'm not prepared to explain that (mostly because I frankly don't understand it).
