I see that the converters for the 4 cyl and 6 cyl are smaller than the ones for the v8 with the same trans. Will the smaller one work behind the v8 like a stall converter? We used to use vega converters in our th350 and they stalled around 2300.

 

If the bell housing is different, then the input shaft is different also, and the torque converter to crankshaft hub is too. No, it will not interchange.

 

Old school. - You should see what those vega converts do in a th400 behind a bbc. - They really don't like t-brake launches, but work pretty well foot-braking.

The only drop-in v6 tc is the s10 4.3 converter. IIRC, it's known as a B29 and will give you around a 2k-2200 stall.


Although they work fairly well, just as the vega converter, it's not nearly as efficient as a properly built stall converter.
