stock A904 converter ratings

Here's a link that you should use before you order your converter. They have a high stall spec sheet you can download and fill in the information needed to get the RIGHT STALL converter for your application. Give the converter supplier all the information that you've done to the engine, tire size, axle ratio, cam specs etc. DON'T BS them, because if you do, the converter may not work the way you want it to. If you've got a real dyno sheet, send that information also.

Also, watch out on the year. Chysler started to use lockup converters in the late 70's.
