What is a 472 bore 060 over?

A 472 bore 060 over refers to a specific engine modification where a 472 cubic inch engine (commonly associated with Cadillac) has been bored out by 0.060 inches, increasing its cylinder diameter for enhanced performance. This alteration typically allows for greater airflow and fuel intake, potentially leading to increased horsepower and torque. The term "060 over" indicates the extent of the boring process, which can also improve engine efficiency. However, such modifications should be done with care to maintain engine reliability and longevity.
