The inclusion of an engine claim rule within the framework of the Grand American Modified division rules is essential to the success of the division. The claim rule is designed to help control the cost of racing while, at the same time, ensuring closer competition.

Once the top four finishers are in the designated claim area, an eligible driver prepared to claim shall present $850 in cash and a valid NASCAR license to the NASCAR official in charge. The driver subject to claim will either accept or deny the claim. If denied, the competitor is subject to refusal penalties. If accepted, the driver making the claim will proceed to the inspection area and be inspected for the following:

* Ground clearance four-inches (measured to lowest point on frame rails) with driver.

* Engine height minimum no less than 11-inches from ground to front center of crankshaft.

If the car claiming is deemed legal, the claim may proceed. If claiming car does not meet criteria set forth for inspection, monies will be returned and claim dropped.

At no time during this procedure will a protest be considered in an effort to stop a claim. A protest will only affect points, money and position. The claim rule and protest procedure are separate issues and will not interfere with each other.

It is important that race officials handle all claims swiftly; and for all participants to remember that the claim rule is in place to help the division, not complicate it, and that when you enter, you are subjecting yourself to it.
