421 Day!
This event honors the legendary 421 inch Super Duty Pontiac engine. Gateway had not historically had an event on this day, so Steve Hedrick launched an effort to change that. Steve arranged with the Sawmill BBQ and Pub in Des Peres to host the event. In further homage to Pontiac and The Great One, the start time for the event was set for 242 (the VIN numbers that indicate a real GTO for model years 1966 to 1971).
