the only way I know is to install them put it in gear & see where the converter stalls against the power of the engine

Converter Stall
What size are they, 11" or 12"?
A 12" Chrysler converter has a narrow ring gear, and the 11" has a wide ring gear from the factory. Chrysler stall speeds depended on the engine that was in front of it. Both size converters have been used behind everything from the leaning tower of power to the 440.
Also, if you're thinking of using them, don't(IMHO), as you really don't know what condition they are internally. I worked in the transmission parts industry for a lot of years, and saw a lot of converters (stock and high performance) apart in the converter shop. Lots looked good on the outside, but internally bearings, washers and sprags were either going or gone.

+ if the last trans they came out of failed they will be full of debris from that failure , any used converter is a paper weight in my mind

Sorry for the thread hijack here but how do I find the stall if I don't have a tach?
After all of the tuning and the parts that I have I am rather certain that I need a higher stall.
When in D, it idles so slow that everything shakes and it nearly dies. We played a lot with the carb and the timing, and its better, but still not quite there.
The cam (we found out when doing the head work) is a Mopar Performance Purple 282/484.
My guy here that helped me do all this work suggests a 2600-2800 stall but admits to not being a transmission specialist.
Does that seem about right?

I have same cam and same problem. Most have said that the 2500 range is probably right. Depends on hp, torque, and gearing. The actual stall will vary. The power band for that cam comes in at about 2500 rpm.

Without a tach, it's very difficult to know where the converter usually stalls.
I'm going to repost a specification sheet we used to determine the high stall that matched "YOUR" application. I tried to post it here, but it wouldn't load so I'll post it in the transmission section.
If you've got any further questions, please feel free to email me at home.
