LS Engine And LSX Differences Compilation
LS Engine And LSX Differences Compilation Posting this here for my own quick reference.
5.7L LS1 – 97-04 Corvette, Camaro, Firebird and GTO. Use cathedral-port heads
5.7L LS6 - 01-05 Corvette Z06, 05 Cadillac CTS-V. LS6 production engine uses a unique block casting with enhanced strength, greater bay-to-bay breathing capability and other minor differences. The heads, intake manifolds and camshaft also are unique LS6 parts. Uses cathedral-port heads
6.0L LS2 – 05-07 Corvette Base, GTO, SSR roadster, Pontiac G8 GT. LS1, LS6, LS3 and L92 cylinder heads work well on it. Uses cathedral-port heads. Can use L92-style heads due to it’s 4.00-inch bore.
6.2L - LS3/L99 – 08 Corvette, Pontiac G8 GXP, 2010-2014 Camaro SS auto uses L99, while the manual uses the LS3. L92 style rectangular port heads. Can use any head except for the LS7 and C5R.
5.3L LS4 - Front-wheel-drive Chevrolet Impala SS and Pontiac Grand Prix GXP. Aluminum block.
7.0L LS7 – Standard in 06-13 Corvette Z06/427 (no 427 trim in 06&09) and 2014 Camaro Z/28, Siamese-bore cylinder block design. Uses LS7-style rectangular port heads. Can use any LS-series head, but shoud use heads designed for at least 4.10-inch bores; and 4.125-inch bores are preferred.
6.2L LS9 – 2009-2013 Corvette ZR1. Roto-cast cylinder heads and a sixth-generation 2.3L Roots-type supercharger. Like the LS7, it uses a dry-sump oiling system. L92 style rectangular port heads. Can use any head except for the LS7 and C5R.
6.2L LSA- A detuned version of the LS9. Standard in the 2009 Cadillac CTS-V, 2012-2014 ZL1 Camaro, Hypereutectic pistons vs. the LS9's forged pistons; and a smaller, 1.9L supercharger. L92 style rectangular port heads. Can use any head except for the LS7 and C5R.
6.2 L LT1 V8 – 2016/2017 Camaro SS Corvette Stingray, 2017 Corvette Grandsport, 2016 Corvette Stingray, 2015/2014 Corvette Stingray & Z51
6.2 L LT4 - 2017 Corvette Z06 & Camaro ZL1
6.0 LQ 9 - 02+ Escalades and 03+ SS Silverado's and some special order 05-07 Classic Silverado's V-MAX, all with 8th digit vin: "N". Has 317 heads with flat top pistons.
6.0 LQ 4 - 01+ Denali's, 00+ Truck variant's, and Vans, all with 8th digit vin: "U". Has 317 heads with dish pistons.
4.8L Vortech Truck – Iron block with 3.78-inch bores and aluminum heads.
5.3L Vortech Truck - The same iron block with 3.78-inch bores as the 4.8L, but with a longer stroke , (3.62-inch)crank.
6.0L – Vortech Truck used primarily in 3/4-ton and 1-ton trucks, iron block (LY6) or aluminum block (L76) and aluminum heads. L92 style rectangular port heads.
6.2L – Vortech Truck - L92 aluminum block and heads, and incorporates advanced technology including variable valve timing. Cadillac Escalade and GMC Yukon Denali.
LSX Bowtie Block (standard and tall-deck) - 2007, cast iron casting that was designed to support extreme high-performance combinations, including provisions for six-bolts-per-cylinder head fastening. It has a Siamese bore design with 3.99-inch bores that must be finished to 4.00 inches - with a 4.25-inch recommended maximum bore. Maximum stroke can reach 4.25 inches, but rotating assembly interference on the cylinder must be taken into account for strokes greater than 4.125 inches; heavy metal is required for crankshaft balancing of larger-stroke combinations. Standard versions feature decks 0.020-inch taller than LS production blocks, with the tall-deck version manufactured with a 9.70-inch semi-finished deck height. The oiling system is a true priority-main system and all LS small-block heads work with the engine. Higher-airflow heads, such as LS7 and C5R, are recommended.
Most LS production cylinder blocks share the came cylinder head bolt pattern and the same size head bolts - four 11mm bolts per cylinder (10 in total) and five upper, 8mm bolts. Early LS1 and LS6 engines used different-length 11mm bolts, but engines from 2004 and later use same-length bolts. LS9 engines use stronger, 12mm head bolts.
