In an intriguing barn find in Oklahoma, vintage Chevrolet expert Patrick Glenn Nichols uncovered a small collection of 1960s and 1970s cars, featuring notable 409-powered Chevrolets. The 409 refers to the renowned W-series engine, available from 1961 to 1965, with a displacement of 409 cubic inches (6.7 liters).

The 409 engine, introduced in late 1960, was a significant powerhouse in the early 1960s American auto industry. It was derived from the 348 cubic inch (5.7 liters) V8, marking Chevrolet’s first big-block mill. Ranging between 360 and 425 horsepower, depending on the carburetor configuration, the 409 was a pioneering unit delivering one horsepower per cubic inch.

The collection includes four Chevrolets with the potent large block, showcasing the owner’s enthusiasm for this iconic engine. The lineup features a 1961 Bel Air, a first-year model with 360 horsepower, showcasing its original and unrestored condition. The second is a 1962 model, painted in red, with 380 or 409 horsepower, depending on the carburetor configuration.

As the exploration of the barn continues, a third Bel Air 409 emerges, a 1963 model in light blue, well-preserved despite the layer of dust. The fourth is a 1964 Biscayne, a white-colored sleeper with a two-barrel setup delivering 340 horsepower.

Beyond the 409-powered Chevys, the extensive barn houses other gems, including a 1963 Impala, a 1955 Tri-Five, a 1968 Camaro SS 396 with an L78 V8, and several C10 pickup trucks. While there’s no information on how long these vehicles have been sitting, the allure of the quarter of 409-powered Chevys makes them a standout highlight in this remarkable barn find.
