I have a 10" high stall converter that I purchased last year from Darrin at BCAutomotive. It was manufactured by Circle D performance. It has a stall of 3600 I believe it is. I ran it for approximately 5000 miles before disassembling my project and have only ran Mercon V through it. It is in great shape and never had any problems. I originally paid 800 dollars for this part brand new so my loss is your gain. It will fit any car or truck that runs the 4R70W transmission. Please feel free to contact me with any questions that you have. Thanks for looking.
