The popular Chevelle SS 396 series continued for 1967 with a mild restyling and refinements to the SS appearance package. The SS 396 again offered only big-block power, with factory brochures officially listing just two power levels: from the basic L35 V8 with 325 hp to the wilder L34 with 350 hp, 10 fewer than in 1966.
Not included in official 1967 Chevrolet marketing, however, the 375 hp L78 V8 was indeed available as a little-known dealer-installed option, with estimates placing the number of Chevelles so equipped at just over 600 units. Curiously, while nearly identical to the 396-cube V8 that powered the 1965 Corvette at 425 hp, the L78 was rated at 50 fewer horsepower when installed in the Chevelle.
Regardless, the L78 included such desirable features as a heavy-duty cylinder block with four-bolt main caps, 11.0:1 compression ratio, mechanical valve lifters, an upgraded cam and an 800-cfm Holley four-barrel carburetor on an aluminum intake manifold.
This car was auctioned off by RM Auctions in June of 2010 at the Town and Country Resort & Convention Center, San Diego, California.
