1971 Chevrolet Corvette

1971 Chevrolet Corvette Stingray LT1 Convertible Numbers-Matching, M21 4-Speed, Mulsanne Blue


Why This Car Is Special

The 1971 Chevrolet Corvette Stingray is one of the most important years in C3 history, and not for reasons that are always obvious at first glance. By 1971, General Motors had mandated that all its engines be capable of running on regular low-lead fuel, and compression ratios were dropping across the board. The base 350 fell to 270 horsepower. The big-block 454 saw similar cuts. But the LT-1 the solid-lifter, high-revving 350 developed largely by Zora Arkus-Duntov held the line. In 1971, the LT-1 was rated at 330 horsepower, making it the highest-output small-block Corvette engine available that year and the last truly high-compression LT-1 before emissions and fuel quality requirements significantly softened the formula in 1972.

That context matters because it tells you exactly what this car is. This 1971 Chevrolet Corvette Stingray LT-1 convertible is a numbers-matching example of arguably the best driver's Corvette of its era. The LT-1 was never the biggest engine in the Corvette lineup, but it was the one the factory engineers built for people who actually wanted to drive. Its solid-lifter cam, high-compression heads, and free-breathing induction gave it a character that the big-blocks couldn't match through corners. Paired here with the M21 close-ratio 4-speed manual the gearbox specifically paired with the LT-1 to make the most of its power band this is the drivetrain combination that Corvette enthusiasts have sought out for decades.

The VIN decodes to confirm this car was built as a convertible at the St. Louis assembly plant in 1971, with the LT-1 engine and the S-suffix indicating it is a genuine open-body car, not a T-top coupe. Everything about this car's specification points to a buyer who ordered it to drive, not just to park. Mulsanne Blue over a matching blue vinyl interior is a factory-correct, period-appropriate combination that suits the lines of the C3 body exceptionally well.

Fewer than 5,300 LT-1 Corvettes were produced for 1971 across both coupe and convertible body styles combined. The convertible was already becoming a smaller part of the mix as buyers shifted toward the T-top, making a genuine LT-1 convertible a relatively scarce configuration within an already low-production engine option.

Mechanical

The heart of this 1971 Corvette Stingray is the numbers-matching LT-1 350 cubic inch V8 rated at 330 horsepower. To understand why this engine matters, you have to understand what it was designed to do. The LT-1 used a solid-lifter camshaft, an 11.0:1 compression ratio in 1971, large-port cylinder heads, and a single four-barrel carburetor on an aluminum intake manifold. It was not a torque engine in the traditional sense it rewarded drivers who were willing to work the gearbox and keep the engine in its power band. That is precisely why it was paired from the factory with the M21 close-ratio Muncie 4-speed, a gearbox with tighter spacing between ratios than the wide-ratio M20. The combination suited road course driving as well as spirited highway use.

The M21 close-ratio 4-speed shifts with the mechanical precision you expect from a M
