Hey, I am installing a new engine into my 84 cutlass (don't worry it's a Buick 350 replacing a buick v6) The engine was rebuillt 8000 miles ago, as was the th350 tranny. The problem is neither me or the seller knows what cam is in the engine, or what the stall speed is of the convertor. So here's where it gets a little more tricky, the Cutlass has a 2.41 rear end, not good I know but I am on a ultra slim budget, and when I finally do change the gears they will get no higher then 3.08's. So should I go with my old "towing" convertor which stalls at 1500, or go with the convertor that we think stalls somewhere between 2400-2800? I'm thinking the low stall would be better since I never push the RPM's past like 2400 on the highway. What about saving a few bucks and getting a TCI sizzler convertor? Let me know, sorry to confuse you all but any help would be great Thanks Jason
Jason, I would stick with the low stall converter. BTW, there is no such thing as set stall speed for any converter, just a stall speed range. A converter that stalls at 1500 behind a V6, will stall higher behind a V8 because the V8 will make more torque. Also a converter will stall higher in a heavier car, and stall lower in a lighter car. The tall highway gearing will also make the converter stall somewhat higher.
