The Legendary 1967 Chevrolet Corvette ‘Big Tank’ Reveals Its Hidden Mysteries

Unleashed in 1963, the second-generation Chevrolet Corvette brought a wave of innovations to the iconic nameplate.

From the coveted “Sting Ray” emblem to the debut of the coupe body, it also made history as the first-ever to house a beastly big-block V8 engine. But that’s not all – this beauty also boasts a split rear window, a feature exclusive to the 1963 model, and the option for a rare oversized gas tank that no other Corvette has ever seen.

The 1967 Chevrolet Corvette “Big Tank” was designed for those who wanted to race the C2 at Sebring and Daytona, and it was originally included in the Z06 package. The C2 already had a larger fuel tank than the C1, going from 16 to 20 gallons (61 to 76 liters), but the “Big Tank” option was massive, with a capacity of 36.5 gallons (138 liters).

Chevrolet later dropped the oversized tank from the Z06 bundle. Still, it remained an option for any coupe through 1967, when the C2 was discontinued to make way for the third-generation Corvette. While desirable among racers, the “Big Tank” option wasn’t very popular. Only 63 Z06s were fitted with the option in 1963, and only 38 Corvette customers went with it in 1964.

Production remained low in 1965, with only 41 built, but grew to 66 examples in 1966. For the C2 Corvette’s final production year, only two customers opted for the “Big Tank” option.

All told, these “Tanker” cars are very scarce, and you’d be hard-pressed to buy one and see one in the metal. Notably the 1967 version, which is the very definition of “rarer than hen’s teeth.”

Unless you get extremely lucky, this video showing the only white “Big Tank” Corvette built in 1967 (the other one is red) will be your closest encounter with such a rare classic. A highly documented and finely restored Corvette, this “Tanker” is also loaded with options, featuring air conditioning, power windows, power steering, power brakes, tinted glass, and a 3.36 Positraction rear end.

And while it’s finished in a rather boring (to me) Ermine White, it comes with a spectacular Bright Blue vinyl interior.

Despite being produced during the C2’s final year, when Chevrolet offered 427-cubic-inch (7.0-liter) big-block mills rated at 390 and 435 horsepower, this “Big Tank” version rocks a 327-cubic-inch (5.4-liter) small-block V8.

It might not be quite as potent at 350 horsepower, but the four-speed manual and the 3.36 rear end must make it a hoot to drive. And I bet it would be pretty fun to race as well.

But my favorite cool fact about this Corvette is that it is part of a collection that includes “Big Tank” cars from every single model year. Now that’s what I call a unique classic car garage!

Michael completed his collection in 2018, when he bought the car you see here at auction from the Richard Cohen collection. And it was anything but cheap at $418,000, including buyer premium.

This ultra-rare 1967 Chevrolet Corvette “Big Tank” is worth a pretty penny – to the tune of over half a million dollars.

And with the soaring prices of classic cars and its status as one of the most unique C2s in existence, it’s only a matter of time before it crosses the million-dollar threshold in the next few years.
