LS2 – 6.0lt – 364ci

The LS2 400 bhp (300 kW)@6000rpm and 400 lbf·ft (540 N·m)@4400rpm from a slightly larger displacement of 5,967 cc (5.967 L; 364.1 cu in). It is similar to the high-performance LS6, but with improved torque throughout the rpm range. The LS2 uses the “243″ casting heads used on the LS6 (although without the sodium filled valves), a smaller camshaft, and an additional 18 cubic inches. The compression of the LS2 was also raised to 10.9:1 compared to the LS1s 10.25:1 and the LS6s 10.5:1. The LS2s in the E-series HSVs are modified in Australia to produce 412 bhp (307 kW) and 412 lbf·ft (559 N·m).

L76 – 6.0lt – 364ci

L76 was originally Holden’s version of the 5,967 cc (5.967 L; 364.1 cu in) Generation IV engine. While displacement on demand technology was disabled on Holdens, this feature is enabled on the 2009 model Holdens with AFM, but only on models fitted with the 6L80 Automatic Transmission. The engine also meets Euro III emissions requirements. Output is 348 bhp (260 kW)@5600rpm and 376 lbf·ft (510 N·m)@4400rpm for the Holden variant.

Applications:

2006 Holden VZ Late Models
2006 Holden WL Statesman/Caprice – Those built from February 2006 until September 2006 until the release of the WM series.
2009 Holden VE Commodore
2009 Holden WM Statesman/Caprice
2009 Holden VE Ute

 

L98 – 6.0lt – 364ci

The L98 is a slightly modified version of the L76. Since Holden did not use the displacement on demand technology of the L76, some redundant hardware was removed to form the L98. Power increased to 362 bhp (270 kW)@5700rpm and 391 lbf·ft (530 N·m)@4400rpm. As of February 2009 Holden have used AFM in the L76 block which has been available in all automatic V8s

Applications:

2006 (MY06) Holden VZ SS Thunder Ute
2006-2009 Holden VE Commodore
2006-2009 Holden WM Statesman/Caprice

 

LS7 – 7.0lt – 427ci

The LS7 is a 7,011 cc (7.011 L; 427.8 cu in) engine, based on the Gen IV architecture. The block is changed, with sleeved cylinders and a larger 4.125 in (104.8 mm) bore and longer 4.00 in (102 mm) stroke than the LS2. The small-block’s 4.4 in (110 mm) bore spacing is retained, requiring pressed-in cylinder liners. The crankshaft and main bearing caps are forged steel for durability, the connecting rods are forged titanium, and the pistons are hypereutectic. The two-valve arrangement is retained, though the titanium intake valves by Del West have grown to 2.20 in (56 mm) and sodium-filled exhaust valves are up to 1.61 in (41 mm).

Peak output is 505 hp (377 kW) at 6300 rpm and 470 lb·ft (640 N·m) at 4800 rpm with a 7100 rpm redline[citation needed] During GM’s reliability testing of this engine in its prototype phase, the LS7 was remarked to have been repeatedly tested to be 8000 rpm capable, although power was not recorded at that rpm level, due to the constraints of the camshaft’s hydraulic lifters and the intake manifold ability to flow required air at that engine speed.

The LS7 is hand-built by the General Motors Performance Build Center in Wixom, Michigan. After an extensive engineering process over several years, Holden Special Vehicles fitted the LS7 to a special edition model, the W427. The HSV-tuned engine produces 375 kW (503 hp) and 640 N·m (470 lb·ft), making it the most powerful car ever built in Australia. The W427 was unveiled at the Melbourne International Motor Show on 29 February 2008 and went on sale in August 2008.

Applications:

2008 HSV W427

 

LS3 – 6.2lt – 376ci

The LS3 block is an updated version of the LS2 casting featuring a larger bore of 4.06 in (103 mm) creating a displacement of 6,162 cc (6.162 L; 376.0 cu in). It also features higher flowing cylinder heads sourced from the L92, a more aggressive camshaft with 0.551″ lift, a 10.7:1 compression ratio, a revised valvetrain with 6 mm (0.24 in) offset intake rocker arms, a high-flow intake manifold and 47 lb/hr fuel injectors from the LS7 engine.

The L76/L92/LS3 cylinder heads use 2.165 in (55.0 mm) intake valves, and 1.59 in (40 mm) exhaust valves. Improved manufacturing efficiency makes these heads cheaper than the outgoing LS6 heads, and severely undercuts aftermarket heads. The large valves, however, limit maximum rpm – 6000 in the L76 (with AFM), and 6600 in the LS3 (with hollow stem valves).

In addition to the above, a dual mode exhaust package with a bypass on acceleration is available. The dual-mode exhaust uses vacuum-actuated outlet valves, which control engine noise during low-load operation, but open for maximum performance during high-load operation. The system is similar to the C6 Z06, but uses a 2.5 in (64 mm) diameter exhaust compared to the Z06′s 3 in (76 mm). Power is boosted to 436 hp (325 kW) and 428 lbf·ft (580 N·m) with this option.

From April 2008, Australian performance car manufacturer, HSV, adopted the LS3 as its standard V8 throughout the range, replacing the LS2. The LS3 received modifications for its application to HSV E Series models, producing 425 bhp (317 kW). The LS3 engine in the E Series II GTS (released September 2009) was upgraded to produce 436 bhp (325 kW).
