Thunder Stock

Sponsored by Brock Salvage, Auto Clearing Motor Speedway's Thunder Stock cars are designed as an entry level division utilizing big heavy cars that are a challenge to handle on a race track.

Minimum wheelbase of a thunder is 114 inches making cars such as a full size Chevrolet Impala the car of choice. Full roll cage and driver safety systems are required. Engines are limited to low compression cast iron 350 CID with two-barrel carburetors and stock cast iron manifolds. Body, chassis and suspension components must be stock for the year, make and model used. Tires are limited to street type radial tires that may have been stock on these cars from the factory mounted on eight-inch wide racing wheels maximum.  Thunder Stocks must have a minimum weight of 3600 lbs.

Limitations are designed to keep the division low in cost. During races in this division contact is inevitable because of the size and handling of these cars, in fact, bumping and pushing is encouraged by the officials making Thunder Stock a favourite of the many fans who love to see the crash and bang style of racing.
