So should the machine shop replace my motor? I mean come on 2 pistons are broken and 6 out of 8 have hair line cracks in them i'm not using any of them and i want 8 new pistons and them to rebuild the motor again or is this asking to much the motor had 232 miles on it when i went to the track. i understand a race engine does not really have a warrenty but come on this is builder error not my fault.
