59-Years-Family-Owned 340-Powered 1966 Plymouth Barracuda 4-Speed

Description

OFFERED WITHOUT RESERVE

Introduced during the peak of the pony‑car era, the Barracuda represented Plymouth’s effort to compete with the Ford Mustang and Chevrolet Camaro, offering a sleek fastback silhouette distinguished by its wraparound rear glass. Built on Chrysler’s A‑body platform, the Barracuda blended compact proportions with V8 power, sporty bucket‑seat interiors, and a distinctive design that set it apart from its competitors. The 1966 model year marked the first redesign of Plymouth’s pioneering fastback, bringing updated bodywork, revised trim, and performance options that helped cement the Barracuda’s place among America’s classic performance coupes.

This 1966 Plymouth Barracuda has reportedly remained in the same family for an extraordinary 59 years. Purchased in San Antonio, Texas, in 1967 by the seller’s parents, the seller notes this Barracuda has been cared for across multiple generations. The car retains much of its period correct character with thoughtful modifications performed over the decades.

Though it was built with a 273ci V8, a 340ci four‑barrel V8 said to have come from a Plymouth Duster was installed in 1972. Additional modifications include a Holley‑equipped Six‑Pack induction system sourced from Mancini Racing, replacement of the exhaust, fuel tank, and refreshed steering components. Servicing in 2025 included powertrain, fuel system, and braking system work totaling more than $6,900 .

This 340-Powered 1966 Plymouth Barracuda is now offered with historical documentation, recent service records, a Chrysler Certicard and broadcast sheet, repair manuals, spare parts, and a clean Texas title in the seller’s name.
