The 1953 So-Cal Speed Shop Coupe: A Legendary Double-Threat Hot Rod

The 1953 So-Cal Speed Shop Coupe

The 1953 So-Cal Speed Shop Coupe, built by Alex Xydias and his team, stands as one of the most iconic and versatile hot rods in automotive history. Originally a 1934 Ford coupe, this car was transformed into a record-setting machine capable of dominating both Bonneville Salt Flats and the dragstrip. Its dual-purpose performance earned it the nickname “Double-Threat Coupe” after being featured on the cover of Hot Rod Magazine in 1954.

Origins of the So-Cal Coupe

Inspired by the success of the Pierson Brothers’ 1934 Coupe, Xydias sought a car that could serve multiple purposes: running top speeds at Bonneville and competing at local drag races, all while promoting his renowned So-Cal Speed Shop. He acquired a chopped and channeled ’34 Ford coupe, previously raced by Russell Lanthorne and Jim Gray, which had already proven itself at Bonneville in 1951. The car featured a Frank Kurtis-fabricated racecar-style nose, and Xydias fitted it with a supercharged 1948 Mercury flathead V8 engine. The So-Cal Coupe was finished to a high standard, debuting in 1953 as part of the So-Cal Speed Shop racing team.

Record-Breaking Performance

The So-Cal Coupe made an immediate impact at Bonneville, where it set the C Competition Coupe/Sedan record with a speed of 177 mph. The car also excelled at the dragstrip, achieving 121 mph to set the NHRA B Modified record. The ability to set records in two different racing disciplines showcased the car’s versatility and engineering prowess, further solidifying its “Double-Threat” reputation.

In 1954, Xydias made even more aggressive modifications to the car. The coupe’s top was chopped further, giving it a more streamlined appearance, and the engine was fitted with Ardun overhead-valve heads, boosting its power to over 400 horsepower. With this new setup, the coupe achieved a quarter-mile pass at 132 mph, a remarkable feat for the time.

Tragedy and Retirement

Despite its success, tragedy struck later in 1954 at Pomona. During a race, the clutch exploded at the starting line, igniting a fire that severely burned driver Dave DeLangton, who passed away a month later. Devastated by the loss, Xydias retired from racing and sold the car to John Moxley.

Ongoing Legacy

Even after Xydias stepped away from the racing scene, the So-Cal Coupe continued its record-setting legacy. Moxley raced the car at Bonneville under the name “Miss 400,” setting additional speed records. Over the years, the coupe passed through several owners, including Jim Travis, who set an astonishing 236 mph record at Bonneville with a supercharged Chevy engine.

In 1996, the coupe was purchased by Don Orosco, who restored it to its 1954 configuration with the Ardun heads and supercharged flathead engine. The car made its triumphant return at the 2001 Pebble Beach Concours d’Elegance, where it competed against two legendary Bonneville rivals—the Pierson Brothers’ coupe and Art Chrisman’s Model A competition coupe. The So-Cal Coupe emerged victorious, winning its class and further cementing its status as a hot rod icon.

One of the Most Influential

The 1953 So-Cal Speed Shop Coupe remains one of the most influential hot rods of all time. With its dual-purpose racing capabilities, innovative design, and record-breaking performance, the coupe played a pivotal role in shaping the golden era of hot rodding. Today, it stands as a testament to the creativity, engineering, and competitive spirit that defined the early days of hot rod culture.
