New Arrival! Original 1966 Chevelle SS 396/325hp car tastefully "Day-Two" modified to 375hp L78 specifications. The engine and transmission are the original numbers matching units. The original heads and intake manifold and air cleaner assembly were removed and boxed in favor of L78 spec. Aluminum Intake Manifold and Square Port Heads. A New Old Stock (NOS) NASCAR Cowl Plenum Air Breather Assembly completes the look and rams cold charged air down the carburetor. Interior is factory stock ...black vinyl bench seat interior floor-shifted four with no console. Overall it is clean and original appearing mellowed with time but not worn by any means. High flow exhaust with long tube headers is the only derivation from factory stock appearing on the underside of the car. Factory detail includes the striped markings on the driveshaft. The undercarriage is clean and dry better than you find on most cars that are meant to be driven and enjoyed. If you are looking for the best combination of looks and performance while remaining to true to 1966 then you've found the Chevelle SS you've been hunting!
