The 6.2 L (379 cu in) V8 is the main variant of the Boss engine. The V8 shares design similarities with the Modular Engine family such as a deep-skirt block with cross-bolted main caps, crankshaft-driven gerotor oil pump, overhead cam valve train arrangement, and bellhousing bolt pattern.
1905–1914 Cadillac Model D side-valve (acquired as part of the founding of GM) 1906–1923 Oldsmobile Model S side-valve (acquired as part of the founding of GM) 1906–1911 Buick Model D inline-4 [10] (T-head design, the only non-OHV Buick engine ever made) [11] 1909–1915, 1917–1918 Buick OHV [12] (Model 10 had OHV-4)
Variable exhaust valve timing (the LW2 engine only had variable intake valve timing) Specially-developed fuel injectors. New pistons with pentroof-style centre-domes and valve eyelets for a higher compression ratio of 12.2:1 (compared to 10.2:1 for the dual fuel engine). A new fuel rail and a new LPG fuel filter. Applications:
A solenoid control valve assembly integrated into the engine valley cover contains solenoid valves that provide a pressurized oil signal to specially designed hydraulic roller lifters provided by Eaton Corp. and Delphi. These lifters disable and re-enable exhaust and intake valve operation to deactivate and reactivate engine cylinders . Unlike ...
The two-valve arrangement is retained, though the titanium intake valves by Del West have grown to 2.2 in (56 mm) and sodium-filled exhaust valves are up to 1.61 in (41 mm). Peak output is 505 bhp (512 PS; 377 kW) at 6300 rpm (72.0 BHP/L) and 470 lb⋅ft (637 N⋅m) of torque at 4800 rpm with a 7000 rpm redline. [68]
Thus, these became known as centerbolt valve covers, first introduced in 1985 on the LB4 4.3L V6 and the Corvette a year earlier (the aluminum cylinder heads used with the Corvette were the first to have the centerbolt valve covers). Another improvement was use of a hydraulic lifter/roller camshaft on most 1987 LG4s.
The Calais and Calais V are both available with the 3.6-litre V6 engine used in the SV6, and the 6.0-litre V8 engine is optional on Calais V with active fuel management AFM or DoD, running on four cylinders during low load conditions (6.2-litre V8 engine in VF II) used in the SS, SS V and SS V Redline.
The Chevrolet big-block engine is a series of large-displacement, naturally-aspirated, 90°, overhead valve, gasoline-powered, V8 engines that was developed and have been produced by the Chevrolet Division of General Motors from the late 1950s until present. They have powered countless General Motors products, not just Chevrolets, and have been ...
