It generated 361 hp (269 kW) at 5,600 rpm and 385 lb⋅ft (522 N⋅m) of torque at 4,400 rpm using "regular" gas, or ~87 octane. Redline is 6,000 rpm and the compression ratio is 9.6:1. This engine uses L92 / LS3 style rectangle port cylinder heads, though without the sodium-filled exhaust valves of the LS3. Applications:
The Chevrolet Corvette (C6) is the sixth generation of the Corvette sports car that was produced by Chevrolet division of General Motors for the 2005 to 2013 model years. It is the first Corvette with exposed headlamps (as opposed to hidden headlamps) since the 1962 model. Production variants include the Z06, ZR1, Grand Sport, and 427 Convertible.
The L69 features a compression ratio of 9.5:1 and a relatively aggressive stock camshaft. It also uses a performance-tuned CCC ECM/PROM, a knock sensor, a performance-tuned E4ME 750 cu ft/min (21 m 3 /min) Rochester Quadra-Jet 4 barrel carburetor, and a special, free-flowing exhaust system with large diameter exhaust manifolds, Y-pipe and ...
In 1971, to accommodate regular low-lead fuel with lower anti-knock properties, the engine compression ratios were lowered which resulted in reduced power ratings. The power rating for the 350 cu in (5.7 L) L48 base engine decreased from 300 to 270 horsepower and the optional special high-performance LT1 engine decreased from 370 to 330 horsepower.
The engine featured a 89 mm (3.5 in) bore and a 84 mm (3.31 in) stroke and a 9.6:1 compression ratio. It produced 170–175 hp (127–130 kW) and 190–195 lb⋅ft (258–264 N⋅m). The LG8 was built in Ramos Arizpe, Coahuila, Mexico, and Tonawanda, New York. Applications: 2000–2005 Buick Century; 1999–2003 Chevrolet Malibu
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.
The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu.The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans.
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.
