Any cars running a built engine with a 350 carburetor will be required to weigh a minimum of 3000 pounds with a minimum right side weight of 1350 pounds.

After the fifth race of the season the engine/weight combinations will be reevaluated and any adjustments necessary to properly balance the cars will be made at that time.
