The 1976 four-cylinder engine, as used in the Vega, got some refinements. Named "Dura-built 140", it features quieter hydraulic lifters eliminating valve adjustments. The basic four developed 70 horsepower, but two-barrel carburetion increased the rating to 84. The 1976 model was the introduction of Chevrolet's new 5.0 liter (305 CID) V8 engine with a two-barrel carburetor generating at 3,800 rpm, but only for California and high-altitude Monza customers, and replaced the 350 V8. The 262 was again the optional engine in 49 states. A mid-year option for 1976 was a "Sport" front end available for the Towne Coupe, which featured the 2+2's polyurethane front end and quad headlamps. The Monza Spyder equipment package was introduced in 1976 for both the 2+2 hatchback and Towne Coupe. It featured a two-barrel carburetor version of the four-cylinder engine as standard, a floor console, sport steering wheel, F41 suspension with larger front and rear stabilizer bars, and special shock absorbers. This equipment had been standard on the original 1975 2+2 (excluding the mid-year "S" model).
