will someone explain how stall converters work to me?

im new to automatics and i dont have a clue on how stalls work, whats to big for the street, how do you choose a stall converter for street/strip duty, whats best for my combo, does a 4000 stall mean that it flashes at 4000 or the car wont move with foot on gas and break until 4k. basically anything you guys can school me on the subject would be greatly appreciated. thanx in advance.

Choosing the right stall converter is best left to a knowledable converter manufacturer. They will ask you for a lot of info like camshaft timing, rear end gear, car weight, type of carburetion etc.

They will recommend a size and stall based on a lot of experience and trial and error testing they have done.

Stall is generally how high the rpm will go with the trans locked and the engine at full throttle. (on the trans brake)

On a foot brake car where you stand on the brakes and rev the engine until the rear tire just starts to turn you generally see that stall being a little lower. Then when you let off the brake and mash the gas to the floor the converter will flash to a higher rpm that is probably close to the regular stall rating.

Every car and every combo is different so like I say best to pick a good suppplier close to where you live and have him recomend something. Then if it doesnt work out they will often adjust it for a small fee. sometimes even free if they miss the mark by a lot the first time.

I have a 3500 stall,haven't used it in a while but its' like this, well at least mine is. It is fairly loose,or mooshy like,just as if your clutch was going,but the closer you get to the 3500rpm this firmer it is grabbing,by the time you reach your stall rating it should be pretty much locked up,and your lanching from 3500,not 800 or so like a factory stall.
Also you really want to match your stall with your engine,no use have a stall if you don't need one.

I would highly recommend PTC converters. I do not work for them etc. I have bought 2 converters from them and they were right on with what I wanted and I have had no problems with them. http://www.ptcrace.com/

Steve, Call Kenny Ford @ PTC and ask him this same question. It won't cost you a dime for the answer. He's the man. He came up racing like we did. I used to race footbrake with him and his brother Sam at blue Mntn.

Okay guys I'm gonna hijack this thread a little , tell me if this is right,
I have a C-6 with a full manual reverse pattern valve body, a 3000 rpm stall converter, when I take off in 1st gear it does'nt stall at all as I shift up it does'nt stall, the only time it stalls is when I downshift from 3rd or 2nd to first and jump on it, then it stalls at 3000 (also creates a big grin ). Does this sound right? I've had 2 different converters in the car and it is worked the same way with both
Thanks.
