LS2 can also refer to the 1973–1974 Super Duty 455 cu in (7.5 L) Pontiac V8 engine LS2 can also refer to the 1985 Oldsmobile Diesel V6 engine. The LS2 was introduced as the Corvette's new base engine for the 2005 model year. It also appeared as the standard powerplant for the 2005–2006 GTO.
The 1982 L83 was again the only Corvette engine, producing 200 hp (149 kW) and 285 lb⋅ft (386 N⋅m) of torque from 9.0:1 compression. Since GM did not assign a 1983 model year to production Corvettes, there was no L83 for 1983. [22] This was also the only engine on the 1984 Corvette, at 205 hp (153 kW) and 290 lb⋅ft (393 N⋅m) of torque.
The 2020 Corvette C8 was the first Corvette to have a rear mid-engine configuration, [108] GM's first since the 1984 Pontiac Fiero. The base Stingray coupe was introduced on July 18, 2019, with three launch colors, red (with the Z51 Package), white, and blue, and the convertible on October 2 at the Kennedy Space Center , joined by the C8.R race ...
The 2006 and 2007 CTS-V used the 400 hp (298 kW) 6.0 L LS2 Gen IV V8, similar to that used in the standard Corvette C6.

Prior to 1984, Chevrolet naturally aspirated V8s and Buick turbocharged V6s were popular engines in the GTP class for privateer teams. General Motors (GM) saw the opportunity to enter the IMSA GT Championship for themselves in the 1984 season in competing against Jaguar, Porsche, Nissan and Mazda, but more importantly to expand and explore the limits of the V8 and V6 engine programs.
The C5 was also the first Corvette to incorporate a drive-by-wire throttle; and variable-effort steering, whereby the assist level of the power steering is varied according to vehicle speed (more at lower speeds, less at higher speeds). Also notable, though rarely discussed, the C5 generation was the first model to adopt the parallel or 'tandem ...
Other problems may be implicated in the case of older vehicles equipped with carburetors. Weak, disconnected, or mis-connected throttle return springs, worn shot-pump barrels, chafed bowden cable housings, and cables which jump their tracks in the throttle-body crank can all cause similar acceleration problems.
In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.
