In 2019, GM introduced the L87 as the successor to the L86. La dernière modification de cette page a été faite le 30 janvier 2021 à 16:34. The crankshaft and main bearing caps are forged steel for durability, the connecting rods are forged titanium, and the pistons are hypereutectic. En 1958, les versions 274 et 287 ch (270 et 211 kW) disparaissent. Le LO3 apparait en 1987 pour remplacer les LG4, L69 et LE9 à carburateurs. Réputée pour ses qualités de reproduction, la Ls3/5a a été fabriquée jusqu'au début des années 2000, et de l'ordre de 90 000 paires ont été commercialisées. C'est le moteur ayant eu la plus longue longévité avec le V8 Rolls-Royce. [36], Noonan Race Engineering developed two billet aluminum blocks based on the LS engine. The Vortec 4800 base engines were dropped from the Chevrolet Tahoe and GMC Yukon in favor of the 5300 with Active Fuel Management. The Hennessey Venom GT also uses the LSX engine based on LS7.[35]. Le moteur L-46 est une option disponible sur la Corvette en 1969 et 1970. Le moteur est toujours construit sous forme de « crate engine » (moteur de remplacement prêt à installer). [6] SUV applications are rated at 320 hp (239 kW) at 5400 rpm and 335 lb⋅ft (454 N⋅m) at 4000 rpm. Ce moteur possède une course rallongée (88,4 mm) par rapport au 327. GM labeled it "the most powerful ever offered in Cadillac's nearly 106-year history". [8] Variable valve timing was added for the 2010 model year. Le moteur L69 est une version plus poussée du 305, introduite en 1983. While it has the same displacement the Hennessey Venom GT utilizes an iron block LSX, not an LS7. The LS2 in the E-series HSVs are modified in Australia to produce 412 bhp (307 kW) and 412 lb⋅ft (559 N⋅m) of torque. 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. Structurally, the Gen-V small-block is similar to the Gen III/IV engines, including a deep-skirt cylinder block. La puissance décline dès 1972, avec le ZQ3 n'affichant plus que 203 ch (149 kW) à 4 400 tr/min, et 407 N m à 2 800 tr/min, en raison notamment du taux de compression réduit (8.5:1). The 6.0 L is a larger version of the LS motor. Huit Z06-R ont été construites par Callaway Competition GmbH [29] à Leingarten, en Allemagne, pour la saison 2006. MOTEUR LS3 6.2 litre 500 hp automatique torque TCI stall 2800 avec lock up ,ligne exhausse 3 pouces headers 1 7/8 avec catalyseur high flow suspension hotchkis lower 1 3/8 avec barre de torsion. The system adjusts both intake and exhaust timing between two settings. Cette version est appelée L-84, et il s'agit du plus puissant 327 produit jusqu'alors. It produces 430 bhp (321 kW; 436 PS) at 5900 rpm and 424 lb⋅ft (575 N⋅m) at 4600 rpm without the optional Corvette exhaust and is SAE certified. C'est la dernière année pour le LT-1. À ne pas confondre avec le 307 Oldsmobile, ce moteur est disponible uniquement de 1968 à 1973 sur les modèles Chevrolet. 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. Le moteur L98 est une évolution du 350 originel, dans le sens où il adopte une injection électronique. A 396 cu in (6.5 L) version is used in NASCAR for the Gander Outdoors Truck Series and the ARCA Racing Series as an option engine. The primary difference is that the L96 is Flex-Fuel capable, while the LY6 is not. This is the talk page for discussing improvements to the LS3/5A article. Il est disponible avec un carburateur quatre corps ou une injection mécanique Rochester. 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 disparait en 1992. This family of blocks has seen a wide range of applications from performance vehicles to truck usage. C'est la marque Rogers qui a produit le plus grand nombre de paires du modèle, suivie des marques Spendor, Chartwell, Audiomaster, Harbeth, Goodmans, Richard Allan, Stirling et Kef. The supercharged 6.2L LSA is similar to the LS9 and debuted in the 2009 CTS-V. The LFA is a Generation IV small block V-8 truck engine. À la fin de cette année, le V8 disparait, remplacé par le V8 283 (4,6 L). Like other Gen IV engines, it features variable valve timing. The LH8 is a variant of the 5.3 L Gen IV small block V-8 modified to fit in the engine bay of the GMT 345 SUV and GMT 355 trucks. It is equipped with an Eaton four-lobe Roots type supercharger and has a compression ratio of 9.1:1. : Put new text under old text. 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. Ce moteur présente un alésage de 101,60 mm et une course de 76,2 mm. LSx is also used to denote any LS engine. Toutes ces versions vont disparaitre à la fin de l'année 1961, avec l'introduction du nouveau small-block 327. This category of engines has provisions for high-displacement ranges up to 7,441 cc (7.4 L; 454.1 cu in) and power output to 776 bhp (579 kW). Il a existé en plusieurs versions : Le moteur LG3 est le premier 305 à voir le jour. 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. The L8T is the first iron block member of the Gen V family. Il est équipé uniquement d'un carburateur double corps. features marked with an * indicate that only certain model years have that feature. Ce moteur ne sera plus produit après 1970. C'est à cette famille qu'appartient le célèbre moteur 350, qui est une référence en termes de possibilité de préparation. Click here to start a new topic. VIN code indicating engine RPO is usually not consistent between vehicle types (cars or trucks) or years. C'est la dernière version du 305. The system adjusts both intake and exhaust timing but does not come with Active Fuel Management. Il possède le même taux de compression que le L69. La version L-48 sera produite de 1967 à 1980. The LS7.R engine is a variation of the LS7 used in the highly successful C6.R American Le Mans Series racecar. Firing order is 1-6-5-4-3-2. In 2010, the L9H was further modified with Active Fuel Management, becoming the L94 (in the Cadillac Escalade and GMC Yukon Denali). Some heads with this casting number would fail (but not all of them) as GM had different suppliers for the same head. LQ4s are built in Romulus, Michigan and Silao, Mexico. It has a cast-iron block. Power and torque ratings for SUV and pickup truck applications are the same as each application's LY5 rating. La version à injection dispose elle de 365 ch (268 kW) à 6 000 tr/min, et 477 N m à 4 000 tr/min. L'adjonction d'un détecteur de cliquetis permet d'augmenter l'efficacité de l'allumage. Revised oil pan baffles, or windage trays, are incorporated into the LS4 to ensure that the oil sump stays loaded during high-g cornering. [16] 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. Le 262 a été produit entre 1975 et 1976, date à laquelle il est remplacé par le 305. The engine family commonly called the LS series debuted in 1997. The LFA variant is used in the GM's "two mode" hybrid GMT900 trucks and SUVs, and is an all-aluminum design. Mais en 1971, le taux de compression chute (9.0:1 au lieu de 11.0:1), et la puissance est de 335 ch (246 kW) à 5 600 tr/min. The LS7 is a 7,011 cc (7.0 L; 427.8 cu in) engine, based on the Gen IV architecture. The L8B is an eAssist mild hybrid version of the L83 featuring a .45-KWH lithium ion battery pack. Le LS3 a été présenté comme le nouveau moteur de base de la Corvette pour l'année modèle 2008. The Vortec 4800 LY2 (VIN code "C") is a Generation IV small-block V-8 truck engine. Il remplace le L82, avec une puissance plus faible (193 ch (142 kW) et 380 N m), et un taux de compression de 8.2:1. Ce moteur éphémère sera remplacé en 1982 par le L83. 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). m). This engine produces 403 hp (301 kW) and 417 lb⋅ft (565 N⋅m) in the GMC Yukon Denali/XL Denali, GMC Sierra Denali, Hummer H2, and briefly in the Chevrolet Tahoe LTZ (midway through MY 2008 through MY 2009) and rated at 403 hp (301 kW) and 415 lb⋅ft (563 N⋅m). Ce moteur a la caractéristique d'être réglé pour une utilisation sur circuit, ce qui réduit fortement son usage routier : le couple n'arrive que vers 4 000 tr/min, mais la plage d'utilisation s'étend jusqu'à plus de 7 000 tr/min[1].

Il s'agit d'une version ZQ3 modifiée avec un rapport volumétrique de 11.0:1, pour obtenir une puissance de 355 ch (261 kW) à 5 600 tr/min, et 515 N m à 3 800 tr/min. Save chevy ls3 engine to get e-mail alerts and updates on your eBay Feed. The Vortec 5300 LH9 produces 300 hp (224 kW) at 5200 rpm and 320 lb⋅ft (434 N⋅m) at 4000 rpm. Introduced in January 1995, it is a "clean sheet" design with only rod bearings, lifters, and bore spacing in common with the longstanding Chevrolet small-block V-8 that preceded it as the basis for GM small-block V-8s. LQ9s are built only in Romulus, Michigan. La grande nouveauté de 1957 est l'apparition d'une injection mécanique sur la Corvette. There were two versions of this engine: LQ4, and LQ9, the latter being more performance oriented. Introduit en 1974, sa puissance est de 162 ch à 3 800 tr/min, et son couple est de 339 N m à 2 400 tr/min. En 1959, une nouvelle version à injection apparait : doté d'une avance à l'allumage de 14° et d'un taux de compression de 10.5:1, la puissance est de 294 ch (216 kW) à 6 200 tr/min, et le couple est de 393 N m à 4 400 tr/min. Le premier V8 de cette famille est un 4,3 L conçu pour la Corvette.. Power is boosted to 436 hp (325 kW) and 428 lb⋅ft (580 N⋅m) with this option. 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. Engine VIN code of 5. Cette augmentation de puissance est rendue possible par l'augmentation du rapport volumétrique (11.0:1). Ce moteur, lancé en 1977, est connu pour ses possibilités de préparation, et pour l'interchangeabilité de certaines pièces avec le 350. It can also accommodate variable valve timing. 'Piston slap' sometimes sounds more like a knock or the sound of a diesel engine running. The Vortec 6000 LQ4, is a V-8 truck engine. It also appeared as the standard powerplant for the 2005–2006 GTO. Il possède l'arbre à cames du 350 L83, ainsi qu'un taux de compression de 9.5:1. The block is an updated version of the LS2 casting featuring a larger bore of 103.25 mm (4.065 in) creating a displacement of 6,162 cc (6.2 L; 376.0 cu in). 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. It features either a cast iron or aluminum engine block with cast aluminum heads. It is an iron/aluminum (1999 & 2000 model year engines had cast iron heads) design and produces 300 to 325 hp (224 to 242 kW) and 360 to 370 lb⋅ft (488 to 502 N⋅m). It has a displacement of 5,327 cc (5.3 L; 325.1 cu in)[9] and a compression ratio of 9.9:1. Il a disparu en 1986. While the displacement on demand technology was disabled on Holdens, this feature is enabled on the 2008 Pontiac G8 GT and subsequently refitted in the 2009 model Holdens with AFM enabled, but only on models fitted with the 6L80 Automatic Transmission. Other differences include a slightly lower 9.0:1 compression ratio, single unit heat exchanger and cast pistons. 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). It also features higher flowing cylinder heads sourced from the L92, a more aggressive camshaft with 0.551 in (14 mm) lift, a 10.7:1 compression ratio, a revised valvetrain with 0.236 in (6 mm) offset intake rocker arms, a high-flow intake manifold and 47 lb (21 kg)/hr fuel injectors from the LS7 engine. À partir de 1971, la puissance décline. It was the most basic engine of its family, it did not use any special technology. 425 LB/FT @4600 RPM. The LSA features a smaller 1.9 L (120 cu in) capacity supercharger rather than the 2.3 L (140 cu in) variant of the LS9. However, they all retain their ancestors' two-valve pushrod valvetrain. The smallest member of the Generation IV engine family is unique in that it is the only member of that family that is used in trucks that do not feature variable valve timing. ... Amortissement sur chaussée déformée, « bande son » du moteur trop effacée … Introduced in 2010, the LMF is a lower-tech version used in the lower volume half-ton vehicles cargo vans with AWD that still used the 4 speed automatic, and do not use Active Fuel Management. 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. The 2007 Cadillac Escalade has a 6,162 cc (6.2 L; 376.0 cu in) Vortec 6200 (RPO L92) engine. Toutes les versions à carburateurs quatre corps et deux carburateurs quatre corps utilisent un rapport volumétrique de 9.5:1. Le taux de compression étant de 11.0:1, le moteur développe 375 ch (276 kW) à 6 000 tr/min et 515 N m à 4 000 tr/min.

V8 engines with a 60 degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, … En 1964, la version carburateur quatre corps voit son taux de compression ramené à 11.0:1, et sa puissance augmenter à 370 ch (272 kW) à 6 200 tr/min, pour 475 N m à 4 000 tr/min. The LS4 is a 5,327 cc (5.3 L; 325.1 cu in) version of the Generation IV block. The water pump is mounted remotely with an elongated pump manifold that connects it to the coolant passages. The L77 is rated at 270 kW (362 hp) and 530 N⋅m (391 lb⋅ft) of torque in the manual Commodore SS and SS-V, in automatic Commodores it is rated at 260 kW (349 hp) and 517 N⋅m (381 lb⋅ft) of torque. [7] It has the same compression ratio, power and torque ratings as its predecessor, the LFA. Ce moteur devient le seul moteur à équiper les Corvette, et ce jusqu'en 1965. The L82 uses Active Fuel Management instead of the L84's Dynamic Fuel Management system and is only available on lower-trim trucks. Engines built prior to April 1, 2006 contained AFM components, but the software was not present in the PCM and thus the system was not functional. Les ls3 moteur ne sont pas seulement applicables aux véhicules, mais également idéaux pour tous les types de machines lourdes. It shares its 103.25 mm (4.065 in) bore with the L86, but with a longer stroke of 98 mm (3.9 in) to displace 6.6 liters. Production of the truck-spec L76 started in late 2006, and it was only available with the new body style Silverado and Sierra, as well as the then-new Suburban. The Vortec 6000 or new VortecMax version is based on the Holden L76 engine, and features variable cam phasing, along with Active Fuel Management. The LS7 is hand-built by the General Motors Performance Build Center in Wixom, Michigan. Output is 348 bhp (260 kW) at 5600 rpm and 376 lb⋅ft (510 N⋅m) at 4400 rpm for the Holden variant, and 361 bhp (269 kW) and 385 lb⋅ft (522 N⋅m) for the G8 GT. The six bolt steel main caps are the same ones used on the LS7 engine. Supprimé du catalogue en 1986, ce moteur produit 167 ch (123 kW) à 4 000 tr/min, et 339 N m à 2 000 tr/min. It shares the same bore and stroke as its LQ4 predecessor. The LSX 454 crate engine is a 21st-century upgrade to the legendary Chevy 454 big block race engine - see images, dyno specs, installation info and more. En 1956, la version à carburateur deux corps reste inchangée ; en revanche, les autres versions sont revues, avec un taux de compression porté à 9.25:1. De 1953 à 2019, il était à moteur avant et depuis 2020, il est à moteur central. The LS2 was introduced as the Corvette's new base engine for the 2005 model year. This engine was renamed as the VortecMAX for 2006. Unlike the previous Generation III/IV 3.78 in (96 mm) bore block families, there is no 4.8 L (290 cu in) displacement variant (having been 'replaced' by GM's 5th Generation LT V-8-based V6, the 4.3 L (260 cu in) LV3). 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). 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. We have some of the lowest prices on Chevrolet Performance Parts, Chevrolet Performance Engines, and Chevrolet Performance Transmissions. 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 LH9 was upgraded with Variable Valve Timing (VVT) and flex fuel capability. 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. 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 (76.2 mm). 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. Jeffery Fietz says: October 7, 2019 at 5:57 pm. It produces 367 hp (274 kW) at 5400 rpm and 375 lb⋅ft (508 N⋅m) at 4400 rpm. The stroke is also shorter than the LS7's 101.6 mm (4.00 in), to optimize rod ratio for reliability. Peak output is 505 bhp (512 PS; 377 kW) at 6300 rpm and 470 lb⋅ft (637 N⋅m) of torque at 4800 rpm with a 7000 rpm redline. The majority of V8 engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. 6.0 L blocks were cast of iron, designed to bridge the gap between the new small blocks and big blocks in truck applications. The engine debuted at the auto show in a customized 1969 Camaro owned by Reggie Jackson. The 6.2 L; 376.0 cu in (6,162 cc) LT1 engine debuted in the 2014 Chevrolet Corvette Stingray and is the first Generation V small block engine. En conséquence, ce moteur produit 193 ch (142 kW) à 4 800 tr/min, et 325 N m à 3 200 tr/min. Le premier V8 de cette famille est un 4,3 L conçu pour la Corvette. typical features are AFM (Advanced Fuel Management), VVT (Variable Valve Train), Front Wheel Drive (FWD) and other improvements. It is designed for production-style supercharger and turbo systems used without enhancements or modifications. The block design incorporates turbocharger pressure feed lines in the front of the valley and oil dump ports in the side of the block to return oil to the sump. It is an all-aluminum design which, while still a pushrod engine, boasts variable valve timing. The LH6 produced 300 to 315 hp (224 to 235 kW) and 330 to 338 lb⋅ft (447 to 458 N⋅m). Tous les moteurs sont à soupapes en tête, avec deux soupapes par cylindre. Seule la version à carburateur double corps persistera. 19369326. [citation needed], The 6.2 L; 376.0 cu in (6,162 cc) LT4 engine builds on the design strengths of the previous LS9 supercharged engine used in the sixth-generation Corvette ZR1 and leverages the technologies introduced on the seventh-generation Corvette Stingray, including direct injection, cylinder deactivation, and continuously variable valve timing, to take Corvette performance to an all-new level. Bradford, the LS3 480 horsepower is really just a LS3 with the 219/228 degree duration Hot Cam instsalled. Power output is 755 hp (765 PS; 563 kW) at 6400 rpm and 715 lb⋅ft (969 N⋅m) of torque at 3600 rpm. Bore sizes are up to 4.185 in and stroke up to 4.5 in are available, making a 495 cu in displacement possible. GM issued a TSB on this failure to help service techs identify the problem. The L77 differs from the L76 with its inclusion of Flex-fuel capability, allowing it to run on E85 ethanol. Starting in 2009, it was also available in the Chevrolet Silverado and GMC Sierra, as the L9H, with power ratings of 403 hp (301 kW) and 417 lb⋅ft (565 N⋅m). 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.
