1971 Chevrolet Corvette Stingray Convertible �€" 350/270, Muncie
4-Speed, St. Louis Build Why This Car Is Special The 1971 Chevrolet
Corvette Stingray Convertible occupies a unique position in C3
history. It was the last model year before GM's compression ratio
cuts took full effect across the lineup, and as a result, the 1971
Corvette still carried factory power ratings that buyers in later
years could only look back on with envy. The 350ci small block in
this car was factory rated at 270 horsepower �€" a number that
holds up well even by today's standards for a naturally aspirated
engine of this displacement. By 1972, net horsepower ratings
replaced gross figures across the industry, and the perception of
Corvette performance shifted dramatically. The 1971 model year sits
right at the edge of that transition, making it one of the last
'old school' Corvettes before the emissions era fully arrived.
Total Corvette production for 1971 came in at 21,801 units across
all body styles. Of those, only 7,121 were convertibles �€" exactly
the body style you're looking at here. That's a minority of the
total run, and convertibles have consistently commanded stronger
interest among serious collectors than their coupe counterparts,
especially in desirable color combinations. This car was built at
the St. Louis assembly plant, which produced all C3 Corvettes from
1968 through 1981. Features List - 350ci 270hp V8 engine - Muncie

Louis assembly plant build - 1 of only 7,121 convertibles produced
in 1971 Mechanical The engine under this hood is the 350 cubic inch
small block V8 in its 270 horsepower factory configuration. This
was one of two 350 options available for 1971 �€" the base unit
made 270hp, while the LT1 solid-lifter version topped out at 330hp.
The 270hp variant used hydraulic lifters, making it smoother and
more streetable for daily use, and it paired naturally with the
Muncie 4-speed gearbox this car carries. The Muncie name refers to
the transmission plant in Muncie, Indiana where GM produced its
manual gearboxes, and the Muncie 4-speed was the preferred choice
for Corvette buyers who wanted a mechanical connection to the
drivetrain without the weight and complexity of the close-ratio
race-oriented units. Backing the 4-speed is a Positraction rear
differential, which was standard equipment on the Corvette and
ensured both rear wheels received power simultaneously rather than
spinning the lighter-loaded tire under acceleration. The suspension
on all four corners is fully independent �€" a setup the Corvette
had used since 1963 and one that distinguished it from virtually
every American muscle car of the era, which still relied on solid
rear axles. Four-wheel disc brakes were standard on the 1971
Corvette, another significant advantage over most of its
contemporaries. The undercarriage photos confirm a clean, solid
structure with no visible rot or significant corrosion �€" an
important finding on any C3 that has spent decades in service.

power brakes, a factory alternator, an
