Torque converter crack

TF Patty talked me out of my early race Hemi converter and into a "professionally" rebuilt HS "race" converter. I believe he said it was from a Corvair, and the rebuild included Torrington needle thrust bearings, etc. I believe it only lasted about 20 miles, long enough for me to drive it around the block a few times, and up on a trailer to tow to the races in Spokane, about 300 miles away. I backed it off the trailer and that was it, it would barely move. The converter was toast. The only GM part on the car had failed, hahaha.
