Questions and Answers
What does mean oversize, how can I check what kind of oversize I need?
 

Over time the pistons will wear out the block of the motor and to correct it you take oversized pistons and have a engine shop mechine the block to the pistons so that you have the corrct clearence that you would need. Standard size is 3.750"
