This block is one of three displacements, 302/327/350, that underwent a crankshaft bearing diameter transformation for 1968 when the rod-journal size was increased from the 2 in (50.8 mm) diameter small-journal to a 2.1 in (53.3 mm) large-journal and a main-journal size that was increased from 2.3 in (58.4 mm) to 2.45 in (62.2 mm).
With an identical bore and stroke of 4 + 1 ⁄ 16 in (103.2 mm) and 3 + 3 ⁄ 4 in (95.3 mm) it was precisely half the displacement of the 389 and shared numerous parts with the V8, [4] yet weighed considerably more than half as the engine lower half and block casting were not simply divided down the middle.
The Chevrolet small-block engine refers to one of the several gasoline-powered vehicle engines manufactured by General Motors. These include: The first or second generation of non-LS Chevrolet small-block engines; The third, fourth, or fifth generation of LS-based GM engines; The Chevrolet Gemini small-block engine
Its output of 0.45 hp per cubic inch was 7% better than the 0.42 hp per cubic inch of the popular and widely produced 100 hp (75 kW) 1949 Ford Flathead V8. 1952 88 and Super 88 V8s used a 4-barrel carburetor for 160 hp (120 kW) and 265 lb⋅ft (359 N⋅m), while 4-barrel 1953 versions raised compression from 7.5:1 to 8.0:1 for 165 hp (123 kW ...
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 LLV (also called Vortec 2900) is a 2.9 L; 178.3 cu in (2,921 cc) straight-4 DOHC engine produced between 2007 and 2012, with a 95.5 mm × 102 mm (3.76 in × 4.02 in) bore and a stroke. It replaced the LK5 and produced 185 hp (138 kW) at 5,600 rpm and 190 lb⋅ft (258 N⋅m) of torque at 2,800 rpm.
When describing a crankshaft design, the number of main bearings is generally quoted, as the number of crank pins is determined by the cylinder layout. For example, the Toyota VZ V6 engine is described as having a "four bearing crankshaft" and the Jaguar XK6 straight-six engine has a "seven bearing crankshaft". [2] [3]
The BorgWarner developed turbo can produce up to 27 psi (1.9 bar) of boost thanks in part to its unique dual volute turbine housing and an electrically actuated wastegate. Instead of two side-by-side exhaust passages like on a regular twin-scroll turbocharger , in this design the two exhaust passages are concentric and allow for better use of ...
