The L76 is derived from the LS2, and like the LS2 it features an aluminum engine block. The supercharged 6.2L LSA is similar to the LS9 and debuted in the 2009 CTS-V. La version L-84 disparaitra à la fin de l'année 1965, et en 1967, seule la version 304 ch (224 kW) reste disponible. Le premier V8 de cette famille est un 4,3 L conçu pour la Corvette.. En 1977, la puissance atteint 188 ch (138 kW) à 4 000 tr/min, et le couple 380 N m à 3 200 tr/min. Power increased to 270 kW (362 bhp) at 5700 rpm and 530 N⋅m (391 lb⋅ft) at 4400 rpm. It was crowned as Global Motorsport Engine of the year by a jury of 50 race engine engineers on the Professional Motorsport World Expo 2006 in Cologne, Germany. The Vortec 4800 base engines were dropped from the Chevrolet Tahoe and GMC Yukon in favor of the 5300 with Active Fuel Management. The LS4 is a 5,327 cc (5.3 L; 325.1 cu in) version of the Generation IV block. La version à deux carburateurs à double corps est disponible en version 248 ch (183 kW) à 5 000 tr/min, 407 N m à 3 000 tr/min ou 274 ch (201 kW) à 6 000 tr/min, 386 N m à 4 200 tr/min), mais seulement sur la Corvette. The L96 is essentially identical to its predecessor, the LY6. VÉHICULE INSPECTÉ ET CERTIFIÉ, GARANTIE GM 3 MOIS OU 5 000Km, FINANCEMENT SUR PLACE AVEC TAUX TRES AVANTAGEUX. À la fin de cette année, le V8 disparait, remplacé par le V8 283 (4,6 L). The L98 is a slightly modified version of the L76. Il a disparu en 1986. [32], In 2011, Chevrolet Performance began to offer the build your own engine program for LS7 (part number 19259944) or LS9 (part number 19259945) crate engines. Power and Torque remain the same, but whereas the L86's 'Active Fuel Management' alternates between V-4 & V-8 modes, the L87's 'Dynamic Fuel Management' can alternate between any of 17 different firing orders which vary both how many and which cylinder[s] are actually firing based on demand calculated every 125 milliseconds. There were two versions of this engine: LQ4, and LQ9, the latter being more performance oriented. In 2008 this engine was selected by Wards as one of the 10 best engines in any regular production vehicle. Late Model Swap Hardware (Coming Soon!) This engine is adapted for transverse front-wheel drive applications. 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. LS3 may refer to: GM LS engine; Legged Squad Support System, a military robot. Although smaller than the previous 2.3 L (140.4 cu in) supercharger used on the sixth-gen ZR1, it spins to 5000 rpm faster thus generating boost quicker while making only slightly less total boost than the LS9 engine.[24]. It offers displacements ranging from 364 to 511 cu in (6.0 to 8.4 L) with a bore x stroke of 4 1⁄4 in × 4 1⁄2 in (108.0 mm × 114.3 mm) and is capable of withstanding 2,500 bhp (1,864 kW). Cette augmentation de puissance est rendue possible par l'augmentation du rapport volumétrique (11.0:1). In 2004, Generation III was superseded by the Generation IV. In the case of the LS9, it also means installing the supercharger assembly. In addition to the above, a dual-mode exhaust package with a bypass on acceleration was available on C6 Corvettes. 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. The noise of 'piston slap' often is louder when listening for it below the oil pan. Il est équipé uniquement d'un carburateur double corps. The Vortec 4800 L20 makes more power and features variable valve timing. m). On May 15, 2013, Holden Special Vehicles announced that this version of the LSA engine will also be used in the GEN-F GTS. [8] Pickup truck applications are rated at 315 hp (235 kW) at 5300 rpm and 335 lb⋅ft (454 N⋅m) at 4000 rpm. This engine was renamed as the VortecMAX for 2006. The Vortec 6000 or new VortecMax version is based on the Holden L76 engine, and features variable cam phasing, along with Active Fuel Management. Ce moteur possède une course de 88,39 mm et a été construit de 1979 à 1982. La puissance du moteur augmente d'année en année, pour atteindre 223 ch (164 kW) à 4 400 tr/min en 1988, avec 393 N m de couple à 3 200 tr/min. 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. En 1960, la version à injection voit sa puissance grimper encore (319 ch (235 kW) à 6 200 tr/min), avec une version 279 ch (205 kW) disponible. À l'origine destiné aux pick-ups et utilitaires, ce moteur est installé dans les Chevrolet Caprice et Buick Roadmaster. Il possède l'arbre à cames du 350 L83, ainsi qu'un taux de compression de 9.5:1. Le moteur est toujours construit sous forme de « crate engine » (moteur de remplacement prêt à installer). Il sera installé sur d'autres modèles la même année. It is designed for production-style supercharger and turbo systems used without enhancements or modifications. 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 Generation IV 6000 is a V8 engine that displaces 5,972 cc (6.0 L; 364.4 cu in) from bore and stroke of 101.6 mm × 92 mm (4.000 in × 3.622 in). De 1953 à 2019, il était à moteur avant et depuis 2020, il est à moteur central. Because the positions of the intake and exhaust valves are flipped from where they would be in an LS engine, as well as the need for an addition to the camshaft to drive the high-pressure fuel pump for the direct fuel injection, there is a very little interchange with the Gen III/IV engines. Lire cette actualité automobile du 2007-12-21. Ce moteur devient le seul moteur à équiper les Corvette, et ce jusqu'en 1965. The 7.0-liter V8 LS7 is an engine produced by General Motors for use in high-performance vehicles. Displacement is 5,967 cc (6.0 L; 364.1 cu in) from a bore and stroke of 101.6 mm × 92 mm (4.00 in × 3.62 in). [36], Noonan Race Engineering developed two billet aluminum blocks based on the LS engine. Dingy's Vintage Parts a division of John Scotti Classic Cars Offering a 2008 LS3 Motor Rebuilt in 2018 with a total Bill of $4,973.71 The motor has yet to be install since rebuilt Dingy's Vintage Parts une division de John Scotti Classic Cars Offrant un moteur LS3 2008 reconstruit en 2018 avec une facture totale de $4,973,71 Le moteur n'a pas encore été installé depuis sa … From September 2015 Holden introduced the LS3 in all V-8 models of the VF II Commodore and WN II Caprice-V, replacing the 6.0L L77. It features high-compression (10:1) flat-top pistons for an extra 20 hp (15 kW) and 10 lb⋅ft (14 N⋅m), bringing output to 345 hp (257 kW) and 380 lb⋅ft (515 N⋅m). This family of blocks is just an updated version of its Generation III predecessor with Generation IV updates and capabilities. The Gen IV LS9 is a supercharged 6,162 cc (6.2 L; 376.0 cu in) engine, based on the LS3; the LS7 block was not used due to the higher cylinder pressures created by the supercharger requiring the thicker cylinder walls of the LS3. Disponible sur la Camaro Z28, ainsi que sur la Corvette, il se caractérise par des poussoirs mécaniques, un arbre à cames à grande levée, un carburateur quadruple corps 780 CFM monté sur une pipe d'admission en aluminium, et un échappement à faible restriction. The LSX will be available starting the second quarter of 2007, set to be available in authorized dealerships and retailers on March 31, 2007. Introduit en 1997, lorsque le LS1 a d'abord été offert en Corvette, Camaro, Firebird et modèles GTO aux États-Unis, la série de moteur de LS comprend également le LS2, LS3 / L99, LS4, LS6, LS7, LS9 et les moteurs de LSA, qui ont déplacements allant de 5,3 à 7,0 litres. All HSV MY12.5 excluding the base Maloo and Clubsport variants have been upgraded to produce 436 bhp (325 kW). C'est la dernière version du 305. Un moteur LS9 suralimenté propulsera la Corvette ZR1 2009 Le moteur 265 passe à 283 (4,6 L) par augmentation de l'alésage à 98,4 mm en 1957. En 1968, il est disponible uniquement avec un carburateur deux corps, pour une puissance de 203 ch (149 kW) à 4 600 tr/min, et 407 N m à 2 400 tr/min. En 1979, c'est 198 ch (145 kW) qui seront disponibles, au même titre que 386 N m de couple. Also known as the Vortec 5300, the LH8 was available in the H3 and GM mid-size pickups through 2009. Le moteur L98 est une évolution du 350 originel, dans le sens où il adopte une injection électronique. Ce moteur possède une course rallongée (88,4 mm) par rapport au 327. Though it has the same displacement as the Vortec 5300 LY5, it features an aluminum block instead of iron, and it uses the same cylinder head casting as the Generation III LS6 engine. VIN code indicating engine RPO is usually not consistent between vehicle types (cars or trucks) or years. LS3 peut également faire référence à un moteur Chevrolet Big-Block de 6,6 L (402 pouces cubes) des années 1970 . Power output is 260–295 hp (194–220 kW) and torque is 295–305 lb⋅ft (400–414 N⋅m). It was only available on extended cab 4WD pickup trucks. The LSA has been SAE certified at 556 bhp (415 kW) at 6100 rpm and 551 lb⋅ft (747 N⋅m) at 3800 rpm. Variable valve timing was added for the 2010 model year. The LS7 is hand-built by the General Motors Performance Build Center in Wixom, Michigan. The L20 has a cast-iron block and power output is 260–302 hp (194–225 kW) while torque is 295–305 lb⋅ft (400–414 N⋅m). Toutefois, sa puissance évoluera positivement, avec une augmentation de 15 ch (11 kW) en 1976 (+ 20 N m de couple). It also appeared as the standard powerplant for the 2005–2006 GTO. It has a displacement of 5,327 cc (5.3 L; 325.1 cu in). Le LS3 a été présenté comme le nouveau moteur de base de la Corvette pour l'année modèle 2008. Son taux de compression de 8.5:1 lui permet de produire 142 ch (104 kW) à 3 800 tr/min, et 332 N m de couple à 2 000 tr/min. 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. Tous les moteurs sont à soupapes en tête, avec deux soupapes par cylindre. Au fur et à mesure des années, il s'est modernisé, en adoptant par exemple l'allumage électronique. The LS2 was introduced as the Corvette's new base engine for the 2005 model year.

En 1958, les versions 274 et 287 ch (270 et 211 kW) disparaissent. En 1955, le moteur possède un rapport volumétrique de 8.0:1, un carburateur double ou quadruple corps, et un allumage réglé 4° avant le point mort haut. Il possède le même taux de compression que le L69. The 2007 Cadillac Escalade has a 6,162 cc (6.2 L; 376.0 cu in) Vortec 6200 (RPO L92) engine. Le moteur L69 est une version plus poussée du 305, introduite en 1983. This family of blocks has seen a wide range of applications from performance vehicles to truck usage. The new logo formally adopts the Small Block name for the engines.

The 6.2 liter LS3 V8 engine is currently produced by Chevrolet Performance as a crate engine, offering a peak output of 430 horsepower at 5900 RPM. 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 (290 cc). One unique feature of this family is that the cylinders are siamesed, no water passages between neighboring cylinders. The 6.0 L is a larger version of the LS motor. The longer stroke yields little additional peak torque output compared to the L86, but only requires 87 Octane. Les moteurs et les transmissions LS7 et LS3 sont construits par APP Racing Engines des Pays-Bas. En 1974, il est introduit sur la Corvette comme moteur de base. The crankshaft and main bearing caps are forged steel for durability, the connecting rods are forged titanium, and the pistons are hypereutectic. GM labeled it "the most powerful ever offered in Cadillac's nearly 106-year history". Il était équipé d'un carburateur double corps Rochester Dualjet 210. lsa e-rod 556 hp @6100 rpm 551 lb-ft torque. features marked with an * indicate that only certain model years have that feature. La puissance du L82 augmente d'année en année, pour s'établir à 228 ch (168 kW) pour 5 200 tr/min et 366 N m pour 3 600 tr/min en 1979. Some heads with this casting number would fail (but not all of them) as GM had different suppliers for the same head. The LS2 in the Chevrolet Trailblazer SS and the Saab 9-7X Aero are rated at 395 bhp (295 kW) (2006–2007) or 390 bhp (291 kW) (2008–2009) and 400 lb⋅ft (542 N⋅m) of torque due to a different (sometimes referred to as a "truck") intake manifold that produces more torque at lower RPMs. Ce moteur est supprimé en 1981. It was the most basic engine of its family, it did not use any special technology. Avec un taux de compression de 9.5:1, le moteur développe 253 ch (186 kW) à 5 000 tr/min, et 414 N m à 3 800 tr/min. [17] It was unveiled at the Melbourne International Motor Show on February 29, 2008[18] and went on sale in August 2008. The small-block's 4.4 in (110 mm) bore spacing is retained, requiring pressed-in cylinder liners. Il est disponible avec un carburateur quatre corps ou une injection mécanique Rochester. The L99 is derived from the LS3 with reduced output but adds Active Fuel Management (formerly called Displacement on Demand) and variable valve timing, which allows it to run on only four cylinders during light load conditions. In 2007, wardsauto.com reported that the LS3 (used by 2008 Chevrolet Corvette) and Vortec 6000 LFA (used by 2008 Chevrolet Tahoe Hybrid) engines would be the final two designs in the Generation IV small-block engine family, and the future designs would be part of the Generation V engine family. The engine family commonly called the LS series debuted in 1997. It shares the same bore and stroke as its LQ4 predecessor. It is typically only present when the engine is cold and disappears as the engine reaches operating temperature. À partir de 1971, la puissance décline. La grande nouveauté de 1957 est l'apparition d'une injection mécanique sur la Corvette. The L84 is distinguished from the L82 by the presence of the Dynamic Fuel Management System and is either available or standard on mid- to high-level trims. En 1975, le moteur perd 46 chevaux (34 kW) et 41 N m de couple (208 ch (153 kW) à 4 800 tr/min, 346 N m à 3 600 tr/min). [21] Note: GM previously used the LS9 RPO code on 1969 and later Chevrolet trucks (both 2WD and 4WD) including Blazers, Jimmys, Suburbans, as well as car carriers. Most teams in both series (known as "NT1" in the Truck Series and the "ARCA 396" in ARCA) have switched to the engine because of cost savings. The LS3 was introduced as the Corvette's new base engine for the 2008 model year.

The new (and unrelated) LT5, however, has increased its displacement from 5.7 to 6.2 L (350 to 380 cu in), retains the Gen V OHV valvetrain, and is topped with a 2.6 L (158.7 cu in) Eaton TVS supercharger and an improved intercooler. Avec un taux de compression de 11.25:1, la puissance s'envole à 345 ch (254 kW) à 6 000 tr/min, et 466 N m à 4 000 tr/min. 6.0 L blocks were cast of iron, designed to bridge the gap between the new small blocks and big blocks in truck applications. An experimental engine was built based on L92 engine from Cadillac Escalade, GMC Yukon Denali and Hummer H2, and reported to generate 450 bhp (336 kW) on gasoline via direct fuel injection, increased compression ratio to 11.5:1, and a modified engine controller. The HSV-tuned engine produced 375 kW (510 PS; 503 bhp) at 6500 rpm and 640 N⋅m (472 lb⋅ft) at 5000 rpm of torque. La version à injection possède le même taux de compression, et une puissance de 380 ch (280 kW) à 6 200 tr/min. La version ZQ3 constitue le moteur de base de la Corvette de 1969 à 1973, avant de disparaitre en 1975. Premier moteur small-block, il est conçu pour la Corvette C1 de 1955, afin de remplacer le six-cylindres 235. C'est à cette famille qu'appartient le célèbre moteur 350, qui est une référence en termes de possibilité de préparation. It produces 300 hp (224 kW) at 5200 rpm and 320 lb⋅ft (434 N⋅m) at 4000 rpm. + Update your shipping location 7 S 0 P O N S O A R P A 7 E E D-1-1 U J-1 0 F J-1-1. Il possède toujours un carburateur quadruple corps. The fifth generation of the iconic GM small block engine family features the same cam-in-block architecture and 4.4 in (110 mm) bore centers (the distance between the centers of each cylinder) that were born with the original small block in 1954. The LH6 produced 300 to 315 hp (224 to 235 kW) and 330 to 338 lb⋅ft (447 to 458 N⋅m). The Vortec 5300 LMG (VIN code "0") is the flexible-fuel version of the LY5. C'est le seul moteur à posséder un alésage de 104,78 mm. This is not a forum for general discussion of the article's subject.
