converter stall speed?

I have a basically stock 283 joining to a 700r and was wondering what stall speed do I need for the converter.This is the first automatic I have done so I don't have any experience to gauge this by. I also have only dealt with 350's and VW's. I am guessing 1800 judging by my 350 in my Burb but I think a 283 might need a faster one? Anyone know ?

If you have a basically stock motor, then a basically stock converter would work well, particularly with the low first gear of the 700R4. If you wanted a little more pull in first gear, you might go with the most modest offering by your favorite converter manufacturer. In my opinion, 1800-2200 would be perfect.

Take your little 283's lower torque into consideration when you select an off the shelf converter. It does not make as much torque as a 350 and the converter will probably not reach its advertised stall speed. Depending on the weight of the car, camshaft specs, and compression ratio it could be 300-400 rpms lower than advertised.

I would go with a 2,000 convertor, primarily because of the reduced torque from less cubes... If its a very well built 283 then maybe you can go with a stock stall, but its gonna be a little more sluggish than a 350.

Jim Hand wrote a nice article on converters:

I don't know what the stall speed of a stock GM converter is, but I would guess in the 1500-1800 rpm range.
