Few cars invite closer inspection than a 1963-1967 Chevrolet Corvette. At any show, auction, or cars-and-coffee, someone will eventually lean over the passenger-side fender looking for numbers. There's a good reason: the difference between an ordinary small-block Sting Ray and a documented, original-drivetrain big-block car can be six figures or more.

This guide shows you how to read those numbers, what each one can prove, and where each one stops.

If there’s one car that stirs up late-night garage debates, it’s the early Corvette. The C1 (1953–1962) and C2 “Sting Ray” (1963–1967) weren’t just fiberglass novelties; they defined what it meant for America to have a sports car of its own. The C1 was born out of postwar optimism, initially more boulevard cruiser than true sports machine, but by the time the C2 hit, with its split-window coupe and big-block firepower, the Corvette had arrived.

Now, more than half a century later, the choice for owners and enthusiasts is clear but not simple: do you restore these icons to bone-stock perfection, or do you restomod them into something sharper, faster, and easier to live with?

Let’s grease up our hands and dig in.
