PURE STOCK TRACK DISCLAIMER: 

After every four (4) 'A' Feature wins, a MANDATORY tear-down will be performed by removing one cylinder head, at track's choice. The track has the option for a tear-down after ANY 'A' feature win. If motor is found to be legal, the driver will receive $50 or gaskets. If motor is found to be illegal, or driver/owner refuses tear-down, the driver and car will be disqualified and lose all moneys earned and points for the night.

In an effort to maintain the purpose of the Pure Stock class, as an entry level/beginner class of race cars for drivers; the track reserves the right to ask a driver to move to a more advance class of cars. The track officials will take into consideration the drivability of the driver, years of experience,  feature wins, championships, and listen to the driver's input prior to making an official decision. However, the final decision will rest upon the track official. If a driver wins the championship two consecutive years, he/she will be required to move up a class of cars.
