The first iteration of the W-series engine was the 1958 "Turbo-Thrust" 348-cubic-inch (5.7 L), originally intended for use in Chevrolet trucks but also introduced in the larger, heavier 1958 passenger car line. Bore and stroke was 4 + 1 ⁄ 8 in × 3 + 1 ⁄ 4 in (104.8 mm × 82.6 mm), resulting in a substantially oversquare design. This engine ...
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1] It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed ) an engine might be capable of producing ...
The two inline engines were used through 1954, when Pontiac unveiled its OHV Strato Streak V8 in 1955. The development of this V8 dates back to 1946, when engineers began considering new engine designs for postwar cars. They came up with a 269-cubic-inch (4.4 L) L-head design. Pontiac engineers tested their 269 cu in (4.4 L) V8 in 1949 or 1950 ...
Although it had had a larger displacement than its 261-cubic-inch (4.3 L) Stovebolt predecessor it was approximately 2 inches (51 mm) shorter and 1 ⁄ 4 inch (6.4 mm) lower. [54] Flywheel bolt pattern is the same as the six and V8, with 1 ⁄ 2 inch (12.7 mm) bolts for the flywheel if produced after the 1966 model year.
The engine was sold in different displacements depending on the model of car and the year and was constructed upon two distinct (possibly more) block castings. The engine block in the smaller displacement versions internally resembled the 1937-53 inline Chevrolet 216, 235 & 261" straight six (the combustion chamber design was quite different ...
The 71 refers to the displacement in cubic inches of each cylinder. [1] The firing order of the engine is 1-5-3-6-2-4. [1] The engine's compression ratio is 18.7:1 with a 4.250 inch bore and a 5.00 inch stroke. [1] The engine weighs 2,185 lb (991 kg) and is 54 inches long, 29 inches wide and 41 inches tall. [1]
The Vortec 5000 L30 is a V8 truck engine, displacing 5,020 cc (305.4 cubic inches). Bore is 95 mm (3.7 in) and stroke is 88.4 mm (3.5 in). The compression ratio is 9.1:1. [35] It was replaced by the 4.8 L Vortec 4800 LR4 for the 1999 Chevrolet Silverado/GMC Sierra trucks and 2003 Express/Savana vans. In C/K trucks, the 5000 produces 230 hp (172 ...
The largest engine derived from the series was a 702-cubic-inch (11.5 L) "Twin Six" V12, which had a unique block and crankshaft, but shared many exterior parts with the 351. Diesel versions of the 351, 478 and 637, advertised as the ToroFlow , were also manufactured.
