Up for auction is a high stall torque converter. It stalls somewhere between 3600 to 4000. I know that from putting it in my 69 charger and going off the rpm and the start of the wheel spin. It's a rough guesstimate. But the stall is way to high for me. This converter came with the car as one of two converters. Clearly I picked the wrong one without checking it first. It measures at 10.5 across the top. It's probably more ideal for the big time drag car. I don't know the make or the exact stall of this converter but I know it works. There is no warranty or implied guarantee on this converter and is being sold as is with no reserve. Thanks for looking
