Depending on components and computer module the Vortec 5700 produces 255 hp (190 kW) to 350 hp (261 kW) at 4600 rpm and 330 lb⋅ft (447 N⋅m) to 350 lb⋅ft (475 N⋅m) of torque at 2800 rpm. [ clarification needed ] [ citation needed ] Known as the GEN 1+, the final incarnation of the 1950s-vintage small-block ended production in 2003.
Therefore, they are generally taxed as 1.5 times [citation needed] their stated physical displacement (1.3 litres becomes effectively 2.0, 2.0 becomes effectively 3.0), although actual power outputs can be higher than suggested by this conversion factor. The nominal displacement of a Wankel engine is 3 times smaller than the physical ...
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.
It also replaced the 250 cu in (4.1 L) in the Chevrolet and GMC full-size trucks and full-size vans, and in 1990, it replaced the 292 cu in (4.8 Lsssdrrytgj) in the Step-Vans as the new base six-cylinder engine. 4 The 262 cu in (4.3 L) [convert: invalid option] V6 has a 4 in × 3.48 in (101.6 mm × 88.4 mm) bore and stroke, identical to the 350 ...
The addition of two milled cutouts [in the head] to extend the volume of the combustion wedge can create a compression ratio of 7.5:1; one milled cutout produces a 9.5:1 compression ratio. The difference between the volume of these cutouts provides a wide compression range without making any changes in the piston or cylinder head.
For example, if the static compression ratio is 10:1, and the dynamic compression ratio is 7.5:1, a useful value for cylinder pressure would be 7.5 1.3 × atmospheric pressure, or 13.7 bar (relative to atmospheric pressure). The two corrections for dynamic compression ratio affect cylinder pressure in opposite directions, but not in equal strength.
Their design was based on the Olds 350 gasoline engine architecture. A 350 cu in (5.7 L) V8 was introduced in 1978, followed by a 261 cu in (4.3 L) V8 only for the 1979 model year. In 1982, a 263 cu in (4.3 L) V6 became available for both front front-wheel drive and rear-wheel drive vehicles.
The High Value engine family from General Motors is a group of cam-in-block or overhead valve V6 engines.These engines feature cast iron blocks and aluminum heads, and use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm (3.90 in) bore required offsetting the bores by 1.5 mm (0.059 in) away from the engine center line.
