Torque Converter
 

I have a few torque converters in my garage, one from a 78 Chevy 1/2 ton 350 - 350 combination and one from an 89 1 ton with 454 - 400 combination. Is there anywhere you can find approx. stalls on stock converters?

Can I ask why? To answer your question though, I would try asking a few converter manufacturers. They would know if anyone does...

i will check it out for you when i get to the shop tomorrow,pretty good rule of thumb,the smaller the converter the higher the stall,but there are other things to consider.

There are a lot of people around here building cars and if we had some idea of the stall of the converters , it might save someone some money by using the ones I already have , if we knew some were higher or lower stall to come close to what they might want for there combination.

ok,i checked with my converter guy.here are some generic answers.the 400 converter should have about 1200-1300 stall,the 350 because it is smaller,about 1400-1500,if these converters are stock,if they have been rebuilt all bets are off.also if you sit the converter on a bench,with the hub that goes into the trans sitting straight up,you will see raised ribs on the cover.the ribs that are the greastest distance from the hub signify the stall.if the ribs are leaning to the right the stall will be higher than if the ribs were standing straight,if the ribs are leaning to the left,the stall will be lower.this is true in most cases,esp ford and gm.hope this helps
