We just heard from our customer who's running our main stud girdle with the 935hp low deck with stock caps in a dragster. He pulled the lower end apart and stated that the bearings look as if they only had one run on them and zero signs of cap walk present. Some of Jerry's comments were that the vibration level was extremely low and the dragster was much 'smoother' to run. They turned this engine all season on one set of bearings at 8100rpm. I'm glad we were able to help them out and it looks as though we'll be machining them a new block for next season...
