Custom BTE torque converter. Was a backup to the one in the car. I included the sticker that was provided from BTE on the box. I could figure out how to search the item on their site but if you interested you may be able to call them with those numbers and they can give you the info. Was a g body with a 510 check big block and power glide. Had it built to hold the power we were putting to the ground. Approx 900hp. This auction is for the torque converter only. It will be boxed with the original box inside a new box. You are responsible for determining if it will work with your setup.
