This torque converter is supposed to have a stall around 2500 rpm. It's brand new and has never been used. I bought it as a package deal with a rebuilt turbo 400. However it's not what I need with my combination. Was wanting $350.00 for it, including shipping. Thx, John B.
What specs were you wanting to know of ? Been told it's a good all around street converter for a mild big block Olds Pontiac or Buick.
http://www.a-1perf.com/ Here's a link to the website. A-1 performance converters not to be confused with ATI performance converters. Unless A-1 was bought out by or has become a part of ATI. I'll get you a part number when I get off work. John.
