The Chevrolet Vega is a subcompact automobile that was manufactured and marketed by GM's Chevrolet division from 1970 to 1977. Available in two-door hatchback, notchback, wagon, and sedan delivery body styles, all models were powered by an inline four-cylinder engine designed specifically for the Vega, with a lightweight, aluminum alloy cylinder block.
Aftermarket port fuel injection and re-engineered cylinder heads have been the norm, although parts for the inline-six, such as aftermarket intake manifolds (from a three-carburetor setup or a single 4-barrel carburetor), exhaust headers, and hybrid cylinder heads based on Chevrolet's small-block engine are costlier than those for the small ...
It offers the airflow of more expensive heads, at a much lower cost. It does, however, require a specific intake manifold (the L31 has four bolts per head attaching the intake manifold, as opposed to the "traditional" six bolts per head found on older Chevrolet small-blocks). Chevrolet's L31 was replaced by GM's LS-based 5.3L LM7 and 6.0L LQ4.
The engine came with 543797 (4-barrel) and 9770716 heads for the tri-power and special exhaust manifolds and a 7H cam with 292deg. intake duration and later 1964 L with 288deg intake essentially the same as the 068 cam. #9770716 aka "716" heads featured a 170cc intake port volume, and were considered a milder "street" version of the vaunted ...
The 303-cubic-inch (5.0 L) engine had hydraulic lifters, an oversquare bore:stroke ratio, a counterweighted forged crankshaft, aluminum pistons, floating wristpins, and a dual-plane intake manifold. The 303 was produced from 1949-1953. Bore was 3.75 in (95 mm) and stroke was 3.4375 in (87.31 mm).
Typically, the system is operated by the pilot manually switching the intake air to travel via the heated intake path as required. The carburetor heat system reduces the power output (due to the lower density of heated air) and causes the intake air filter to be bypassed, therefore the system is only used when there is a risk of icing.
