I walked in engine zone about 2 months ago, they had 12 motors and 3 were slugged per there description.. Exact words out of the guys mouth: " we are gonna clean those up and they will be available for sale next week". Then I proceeded to comp test 3 motors as my friend pulled the valve covers on the others. All the motors came back with 1 cylinder down anywhere from 30-60psi from the other 3 cylinders. I won't deal with them ever.
