In 2010, the L9H was further modified with Active Fuel Management, becoming the L94 (in the Cadillac Escalade and GMC Yukon Denali). 8 versions of the Gen IV 5.3L engine were produced: 3 iron blocks (LY5, LMG, and LMF) and 5 aluminum blocks (LH6, LH8, LH9, LC9, and LS4). A version of NASCAR V8 cylinder block cast in Compacted Graphite Iron by Grainger & Worrall won the UK's Casting of the Year Award 2010.The L96 is essentially identical to its predecessor, the LY6.

In the early production run of the LS-series engine, some engines encountered 'piston slap' during the first few minutes after a cold engine start; this sound is caused by the pistons rocking slightly in the cylinder until they reach operating temperature/size. There were two versions of this engine: LQ4, and LQ9, the latter being more performance oriented. It is 5.1 inches (13 cm) shorter than the C5, but the wheelbase was increased by 1.2 inches (3 cm). The L84 is one of two 5.3 liter V8s available in the 4th generation Chevrolet Silverado and GMC Sierra.

(VIN Code "C") Like its Vortec 5300 Generation IV predecessor, it gets its displacement from a bore and stroke of 96 mm × 92 mm (3.78 in × 3.62 in) with a compression ratio of 11.0 to 1. The engine blocks were cast in aluminum for car applications, and iron for most truck applications (notable exceptions include the Chevr… SUV applications are rated at 320 hp (239 kW) at 5400 rpm and 335 lb⋅ft (454 N⋅m) at 4000 rpm.The LH8 was introduced in 2008 as the V8 option for the Hummer H3. Improved manufacturing efficiency makes these heads cheaper than the outgoing LS6 heads, and severely undercuts aftermarket heads. For SUV applications, it is rated at 320 hp (239 kW) and 340 lb⋅ft (461 N⋅m) of torque; while for pickup truck applications, it is rated at 315–320 hp (235–239 kW) at 5200 rpm and 335–340 lb⋅ft (454–461 N⋅m) at 4000 rpm It has a displacement of 5,327 cc (5.3 L; 325.1 cu in)In 2010, the LH8 was replaced by the LH9. Dubbed EcoTec3 5.3 L (320 cu in) is a Generation V small block V8 truck engine. The Generation IV 5.3L engines share all the improvements and refinements found in other Generation IV engines. It gets its displacement from bore and stroke of 99.6 mm × 92 mm (3.921 in × 3.622 in) with a compression ratio of 11.0 to 1. This family of blocks has seen a wide range of applications from performance vehicles to truck usage. The LS3 engine in the E Series II GTS (released September 2009) was upgraded to produce 436 bhp (325 kW). The only engine with this bore size that was used in a production vehicle is the LS7 with the LSX being only for aftermarket use. In 2019, GM introduced the The L8T is the first iron block member of the Gen V family. These V6 engines are based on the V8 version of the Gen V family, but with two fewer cylinders - a design lineage that dates back to the previous 4.3L V6, which was itself a Gen I small block with a pair of cylinders removed. From April 2008, Australian performance car manufacturer HSV adopted the LS3 as its standard V8 throughout the range, replacing the LS2.

This is commonly called the 'Castech Head' failure on the internet. The 6.0 L is a larger version of the LS motor. This family of blocks is just an updated version of its Generation III predecessor with Generation IV updates and capabilities. 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. m).

The Corvette C6 featured new bodywork with exposed headlamps, revised suspension geometry, a larger passenger compartment, a larger 5,967 cc (364.1 cu in; 6.0 L) V8 engine and a higher level of refinement. Power is boosted to 436 hp (325 kW) and 428 lb⋅ft (580 N⋅m) with this option. It has a displacement of 5,327 cc (5.3 L; 325.1 cu in).Inspired by the LS1.R in size and performance goals, this family of blocks was designed for race oriented performance. Firing order is 1-6-5-4-3-2. LSX376-B8 (part number 19171049) is a more economical version that is capable of approximately 8 psi (0.55 bar), for engine producing approximately 600 hp (447 kW). The billet construction provides added block integrity suited to high horsepower applications. The primary difference is that the L96 is Flex Fuel capable, while the LY6 is not. In the early production run of the LS-series engine, some engines encountered abnormal amounts of 'piston slap' - a problem caused by too much clearance between the cylinder bore and the piston. The Generation III small-blocks replaced the LT family in 1997. The program's venue was reported to be relocated to the Corvette assembly plant in Bowling Green, Kentucky.Chevrolet Performance LSX Bowtie block includes LSX specific six-bolts-per-cylinder head bolt pattern, billet-steel six-bolt dowel-located main bearing caps, extra-thick deck for maximum clamping force, extra-thick cylinder walls allow increased bore capacity (maximum 4.2 in (106.7 mm) bore still allows 0.2 in (5.1 mm) minimum wall thickness), true priority main oiling system, main web bay-to-bay breathing holes reduce crank windage, orange powder coat finish, machined bore at 3.88 in (98.6 mm) is ready for final boring/honing. The Chevrolet Corvette is a sports car that has been manufactured by General Motors (GM) since 1953. The Vortec 5300 LC9 (VIN code "3" or "7") is the aluminum block Flex-Fuel version of the LH6, and is found in 4WD models. Based on the Generation III design, Generation IV was designed with displacement on demand in mind, a technology that allows every other cylinder in the firing order to be deactivated. 6.0 L blocks were cast of iron, designed to bridge the gap between the new small blocks and big blocks in truck applications.
