Enthusiasts love classic cars for all sorts of reasons such as the looks, performance, history, and nostalgia. But investment potential is a growing motivation for many. For models like the 1967 Chevelle SS396 L78, authenticity matters a lot. If you’re looking to verify an original 1967 L78 Chevelle SS396, here are 10 steps to help you figure it out.\n

\n<\/p>

To break down VIN numbers, production stats, or just about any factory data, we use ChevelleStuff.net<\/a> \u2014 one of the most comprehensive Chevelle reference sites on the web.<\/p> \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

1. VIN Tag<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Start with the VIN plate on the doorjamb. It should have original star-shaped rivets, which can\u2019t be reproduced. A valid SS396 hardtop will begin with \u201c13817\u201d followed by the model year, assembly plant, and a sequence number that should match other parts of the car.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The trim tag on the firewall tells a detailed story. For example, \u201c06D\u201d shows the car was built in the fourth week of June, and \u201c729-A\u201d indicates a medium blue bench seat. The paint code \u201cF-F\u201d means it was Marina Blue top and bottom. Watch for letter and number combinations that align with factory records.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tThe L78 396ci engine has a specific assembly stamp. \u201cEG\u201d indicates the high-performance version with 375 hp. It should also include a partial VIN that matches the body. Built in Tonawanda, NY, this engine code confirms solid lifters, 11:1 compression, and other high-output features.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t
\n\t\t\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Look for the \u201c3902406\u201d casting number on the rear of the block near the bellhousing. This \u201c406\u201d block is correct for 1967 and must have four-bolt mains to be the true L78 version, not the lower-output L35.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The Holley carb used on the L78 should show part number \u201c3916143CT\u201d with a list number \u201c3910.\u201d A date code like \u201c753\u201d indicates it was made in the third week of May 1967\u2014just right for a June-built car.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

One of the rarest components is the deep-groove pulley on the water pump. Look for the \u201c3862774CW\u201d stamping, unique to the L78 engine. With only 612 L78s built in 1967, finding an original pulley is a big clue.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t
\n\t\t\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The correct distributor for this engine has the number \u201c1111170\u201d and a date like \u201c7E26,\u201d meaning it was made May 26, 1967. That fits the timeline for a drivetrain installed in June of the same year.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

8. Rear Axle Markings<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The rear axle housing will have a code like \u201cKJ,\u201d meaning it came with 3.55:1 gears and an open differential\u2014unusual for such a powerful setup. A build date stamp, such as \u201c0516,\u201d should also match up with the rest of the car.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The M21 four-speed close-ratio transmission has a stamp starting with \u201cP\u201d (for Muncie), followed by the year and date. For example, \u201c7H08\u201d indicates June 8, 1967, which is a perfect match for a car assembled later that same month.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t
\n\t\t\t\t\t\t
\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The heavy-duty radiator used on L78 cars has a small tag stamped \u201cVH.\u201d This was standard for these high-performance models and easy to overlook if it’s missing. The radiator shroud may be aftermarket, but that tag is what matters.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
