1961 CORVETTE SMALL BLOCK 427 TREMEC 5 SPEED
The Chevrolet Corvette (C1) is the first generation of the sports car by the Chevrolet division of General Motors introduced late in the 1953 model year and produced through 1962. It is commonly referred to as the "solid-axle" generation, as the independent rear suspension did not appear until the 1963 Sting Ray. The Corvette was rushed into production for its debut model year to capitalize on the enthusiastic public reaction to the concept vehicle, but expectations for the new model were largely unfulfilled. Reviews were mixed and sales fell far short of expectations through the car's early years. The program was nearly canceled, but Chevrolet would ultimately stay the course and Harley Earl and company would transform the Corvette into a true world-class sports car. Four taillights appeared on the 1961, a treatment that continues to this day. Engine displacement remained at 283 cubic inches, but power output increased for the two fuel-injected engines to 275 hp and 315 hp. Power ratings for the dual-four barrel engines did not change (245 hp and 270 hp) but this was the last year of their availability. This was the last year for contrasting paint colors in cove areas, and the last two-tone Corvette of any type until 1978. Also debuting in 1961 was a new boat-tail design later used on the C2. Rare options: RPO 353 275 hp engine (118), RPO 687 heavy-duty brakes and steering (233), 15x5.5 wheels (357), power convertible top (442). The 1962 model year was the last Corvette with a solid-rear-axle suspension that was used from the beginning. With two new engines it was also the quickest. Engine displacement increased to 327 cubic inches, but dual 4-barrel carburetor engines were no longer available. Hydraulic valve lifters were used in the base 250 hp and optional 300 hp engines, solid lifters in the optional carbureted 340 hp and fuel-injected 360 hp (268 kW) versions. Rocker panel trim was seen for the first time, exposed headlights for the last, until 2005. This was the last Corvette model to offer an optional power convertible top mechanism. Rare options: 24-gallon fuel tank (65), RPO 687 heavy-duty brakes and steering (246), power convertible top (350), 15x5.5 wheels (561).
