( 4 ), Crate Engine, Long Block, 350 C.I. Unfortunately, the system was placed atop the basic LG4 and lacked any significant performance capability. The 350cuin (5.7L), with a 3.48in (88.39mm) stroke, first appeared as a high-performance L-48 option for the 1967 Camaro. of Torque, with Flexplate, Big Block, 8.2L, Chevy, Each, Estimated Ship Date: It had a 3/4-length semi-circular windage tray, heat-treated, magnafluxed, shot-peened forged 1038-steel 'pink' connecting rods, floating-pin in '69, forged-aluminum pistons with higher scuff-resistance and better sealing single-moly rings. During the early 1980s, when GM was streamlining their engine lineups, the Chevrolet 305 would rise to prominence as General Motors' "corporate" engine, signified by being the standard (and often only) V8 in many GM vehicles. General Motors' Generation II LT1 is a small block V8 engine. For the Generation II V8 used from 1991-1997, see, Gunnell, John. Though not offered in GM vehicles since 2003, the 350 series is still in production at a GM subsidiary in Springfield, MO under the company's "GM Genuine Parts" brand, and is also manufactured as an industrial and marine engine by GM Powertrain under the "Vortec" name. RacingJunk.com You are currently viewing Chevrolet.com (United States). The induction system was unlike any system used previously by GM. This new engine family would provide better gas economy than the 350, share its basic architecture and many parts with the 350 (thus reducing production costs), and provide customers with more horsepower and torque than Chevrolet's 1970s-era inline 6 and V6 engines. The exact displacement is 326.7256cuin (5,354cc). The exact displacement is 349.85cuin (5,733cc). Power increased to 180hp (134kW) in 1976 and stayed the same in 1977. 48,619 miles.

The 327cuin (5.4L) V8, introduced in 1962, had a bore of 4.00in and 3.25in stroke. This engine starts as a Dart Little M block that we fully machine and install all new components. [citation needed] The 1997 model year Camaro and Firebird were the last year for this engine in a GM production car before it was replaced by the LS1, which was already in the Corvette for 1997. Also added was a knock sensor to allow the "CCC" engine management system to compensate for the increase in compression and a more aggressive spark-timing map in the ECM. The 265 had a 3.750 inches (95.25mm) bore. A significant improvement over the original Generation I V8 is the Generation II LT1's "reverse cooling" system, allowing coolant to start at the heads and flow down through the block. L05 usage was replaced by the LT1 after 1993 in GM B-Bodies and D-Bodies until production ceased in 1996. A 350 cubic inch version was also used in the Corvette from 1982 to 1984. Power was down in 1971 to dual-rated 330hp (246kW) (gross)/255hp (190kW) (net) and 360lbft (488Nm) of torque with 9.0:1 compression, and again in 1972 (the last year of the LT-1, now rated using net only, rather than gross, measurement) to 255hp (190kW) and 280lbft (380Nm). This block is one of three displacements, 302/327/350, that underwent a crankshaft bearing diameter transformation for 1968 when the rod-journal size was increased from the 2in (50.8mm) diameter small-journal to a 2.1in (53.3mm) large-journal and a main-journal size that was increased from 2.3in (58.4mm) to 2.45in (62.2mm). The 305 is sometimes dismissed in performance circles because of its lackluster performance, small bore size, and difficulty flowing large volumes of air at high RPM. The interchangeable parts include the rotating assembly (crank shaft, pistons, connecting rods, and flywheel/flexplate) one piece rear main seal housing, oil pan and valve cover gaskets and valvetrain assembly (not including timing set, which includes a gear to drive the water pump). The L99's smaller displacement provided slightly better EPA fuel economy than the 5.7L LT1, but at significantly reduced horsepower and torque levels. Low laps. Engines prepared for competition use were capable of producing 465hp (347kW) with little more than the 8-Bbl induction, ported heads with higher pressure valvesprings, roller rocker arms, and the '754 2nd-design road-race cam. It was also very common in Firebirds and Camaros because it was the only engine that offered a 5 speed manual combination. In mid-1996 the L05 was equipped with heads used in the 1996 G30. The first of this family was the 265, introduced in 1954. The car had modified suspension just before release to also be used in local Series Production racing (Australian Group E). Although all of Chevrolet's siblings of the period (Buick, Cadillac, Oldsmobile, Pontiac, and Holden) designed their own V8s, it was the Chevrolet 305 and 350cuin (5.0 and 5.7L) small-block that became the GM corporate standard. [20] All engines in this family share the same block dimensions and sometimes even the same casting number; the latter meaning engines were of the same block, but with different strokes (e.g. [citation needed] In 1968, the last year for factory headers, they had 1.75in (44.5mm) primaries x 3in (76.2mm) collectors. The early Optispark distributor had durability problems, and a revised version was introduced on the 1994 B-Bodies and on the 1995 Y and F-Bodies. In 1972 the L48 (4bbl V8) option for the Nova was part of the SS package. In 1985, this engine was optional only in the Camaro Z28, IROC-Z and Trans Am equipped with the WS6 performance suspension. Known as the GEN 1+, the final incarnation of the 1954 era-vintage small block ended production in 2005 with the last vehicle being a Kodiak/Topkick HD truck. In the ignition system, CCC was fully responsible for the timing curve; mechanical and vacuum advances were eliminated from the distributor. A second generation of the LT5 was in the testing phase as early as 1993. It does not have reverse cooling and is generally not considered a small block Chevrolet. In 1969 it was used in almost all car lines; Camaros, Caprices, Impalas, El Caminos, Chevelles & Novas. The LS9 and LT9 engines were replaced for 1987 by the L05 TBI (throttle-body fuel injection) engines. Standard Catalog of Corvette, 1953-2005. The LS9 used a Rochester 4 bbl carburetor, and its power ratings for 1984 were 165hp (123kW) at 3800 rpm, and 275lbft (373Nm) torque at 1600 rpm. The 400 can have either 2 or 3 freeze-plugs per side though all 400 blocks have the provisions for a 3rd freeze-plug on each side. Referred to as a "small-block" for its size relative to the physically much larger Chevrolet big-block engines, the small block family spanned from 262cuin (4.3L) to 400cuin (6.6L) in displacement. The LT-1 was one of the most well-known SBC V8s, becoming available in 1970. The Vortec 5700 produces 255hp (190kW) to 350hp (261kW) at 4,600 RPM and 330lbft (447Nm) to 350lbft (475Nm) of torque at 2,800 RpM. It was replaced at the end of December 1968 by the L65 and re-appeared again in the 1970's. 530HP EFI Retrofit Dressed Long Block Crate Engines PSLS3760CTF, Chevrolet Performance LS3 525 HP Crate Engines 19432557, Chevrolet Performance LS3 495 HP Long Block Crate Engines 19432424. Production of the original small-block began in late 1954 for the 1955 model year, with a displacement of 265cuin (4.3L), growing over time to 400cuin (6.6L) by 1970.

In 1964, horsepower increased to 366hp (273kW) for the newly named L-76 version, and 375hp (280kW) for the fuel injected L-84, making the L-84 the most powerful naturally aspirated, single-cam, production small block V8 until the appearance of the 385hp (287kW), 395lbft (536Nm) Generation III LS6 in 2001. In 1969 and 1970 it was a 300hp (224kW) version of the 350cuin (5.7L) small-block, with 10.25:1 compression and hydraulic lifters. Displacement is 5,020 cc, (305.4 cubic inches). It produced 190hp (142kW) and 280lbft (380Nm) of torque from 8.2:1 compression, exactly the same as the 1980 L48, but added hotter cam and computer control spark advance, replacing the vacuum advance. The L48 V8 Corvette engine produced 165hp (123kW) in 1975. The 399.9cuin (6.6L; 6,554cc) is the only engine in this family and was introduced in 1970 and produced for 10 years.

We apologize for the inconvenience. This engine was fitted to automatic versions of the 1969 and 1970 Holden Monaro GTS350 in Australia where it was rated at 275hp most likely due to the use of higher octane fuel and far more spark advance than was fitted to North American versions of the engine. The CCC system included the electronic Rochester 4-bbl E4ME Quadra-Jet, with computer-adjusted fuel metering on the primary venturis and a throttle position sensor allowing the CCC to calculate engine load. The Vortec 5700 L31 (VIN code 8th digit "R") is a 5.7L V8 truck engine. They ran 060mph (097km/h) in 2.8 seconds and over 180mph (290km/h). In 1968, the engine had the chrome covers, but without the Chevrolet name, connected to a PCV valve and a chrome 14in 3in (355.6mm 76.2mm) drop-base open-element air cleaner assembly fitted with a crankcase breather on a 780cuft/min (22m3/min) vacuum secondary Holley 4-Bbl carburetor. The principal changes to it over the years include: note 1: depending upon vehicle application; horsepower, torque, and fuel requirements will vary. The 283, famous for being one of the first engines to make onehp per cubicinch, is also famous for being the evolutionary stepping stone that would later give rise to small blocks and to the "W" blocks, ultimately culminating in the Chevrolet big-blocks. [40] GM also took lessons learned from producing a completely aluminum engine and applied them to the new LS series of engines. Fitted with the optional Rochester mechanical fuel injection (FI), it was one of the first production engines to make 1hp (0.7kW) per 1cuin (16cm3). Among the intermediate displacements were the 283cuin (4.6L), 327cuin (5.4L), and numerous 350cuin (5.7L) versions. of 1394, 25 Records Per Page The 400 was made in 4-bolt main journal from 1970 to 1972 and in 2-bolt main journal from 1973 to 1979. The L99 4.3 L V8 was the base engine in 1994-1996 Chevrolet Caprice sedans, including 9C1 police package sedans, and was not available in any other vehicles. The 327 was replaced in the mid 1969 HT Monaro by the 350 L48 developing 300hp (224kW). This variant used a Rochester 2GC carburetor from 1976 to 1978. The 1987 versions had 20hp (15kW) and 15lbft (20Nm) more and a change to hydraulic roller camshaft. Some parts from the Generation II are interchangeable with the Generation I one-piece rear main seal engine. The engine was passed down to 1997 SLP Camaros SS and SLP Firehawks with 6-speed manual transmissions. Bore and stroke were 3.671in 3.1in (93.2mm 78.7mm). A special build 327 was built for GMH for the final run of the HK GTS327 by the Canadian McKinnon Industries. A fully dressed engine includes everything except front A fully dressed engine includes everything except front drive accessories (like alternators and power steering pumps), and even a warranty! Chevrolet went so far as to carry the positive crankcase ventilation system (PCV) over to the cross-ram induction system to retain emissions compliance mandated for US-produced cars beginning in 1967, that also provided full-throttle crankcase pressure venting to the intake air to burn its vapors. It was rated at 230hp (172kW) for 19851986, 240hp (179kW) for 1987-1989 (245hp (183kW) with 3.08:1 rear axle ratio (1988-1989 only)), and 245hp (183kW) in 1990-1991 (250hp (186kW) with 3.08:1 rear axle). See Oldsmobile Diesel engine for more information. Of the three engines in this family, two of them, the 265 and the 283, made automotive history. The 265 cu in Turbo Fire engine was designed by Ed Cole's group at Chevrolet to provide a more powerful engine for the 1955 Corvette than the model's original " Blue Flame" in-line six, the 162hp (121kW) 2-barrel debut version went from drawings to production in just 15 weeks.[17]. The Generation II engine is largely an improved version of the Generation I, having many interchangeable parts and dimensions. A four-barrel carburetor option became available in 1974. Its cast-aluminum LT-1 valvecovers were painted crinkle-black contrasting with the aluminum manifold and distributor housing. Power ranged from 225 to 383hp (168 to 286kW) depending on the choice of carburetor or fuel injection, camshaft, cylinder heads, pistons and intake manifold. In 1983, Chevrolet replaced the cast-iron intake with an aluminum version and used either 14014416 ("416") or 14022601 ("601") heads with 1.84 inch intake valves, 1.50 inch exhaust valves, 58cc chambers, and 178cc runners.

Five different versions between 188hp (140kW) and 283hp (211kW) were available, depending on whether a single carb, twin carbs, or fuel injection was used. Summit also carries other popular crate engine designs, including the Chevy small block 350, the Ford 302 and Coyote, and, of course, the Hemi. All feature a cast iron block, with aluminum heads in the Y and F bodies, and cast iron heads in the B and D bodies. Upgraded to a four-barrel Rochester, dual exhaust "Power Pack" version, the engine was conservatively rated at 180hp (134kW), and with the "Super Power Pack" it was boosted up to the power level of the Corvette. The engine uses a hydraulic roller cam and high flowing, fast burn style vortec heads. The intake manifold to head bolt pattern was redesigned to improve gasket integrity - four of the center intake manifold bolts were drilled at 72 degrees instead of 90 degrees for the cast iron cylinder heads. Engines that were to be installed in the as yet unbuilt ZR-1's were sealed and crated for long-term storage. Unlike the Corvette, the exhaust manifolds were the more restrictive rear outlet 'log' design to clear the Camaro chassis's front cross-member. The LB9 "Tuned Port Injection 5.0L" was introduced in 1985. The Chevrolet Small-Block fundamentally changed the world of engine performance more than six decades ago, and this icon of American horsepower is pulling stronger than ever in Chevrolet Performances diverse range of crate engines. Originally intended as the performance block, this engine family through the 350cuin (5.7L) became an all purpose engine that saw use in many applications from Corvettes to vans. In 1969, factory Z/28's could be ordered with the ZL-1 aluminum-block 427 adaption of the 1967 L-88 427 Corvette cowl-induction 'ZL-2' hood available for both single and dual four-barrel induction systems that were sealed to the air cleaner base ensuring dense cooler, high-pressure, oxygen-laiden air from the center of the base of the windshield was supplied to the engine for combustion smoothness and maximum power production. It used the '202' 2.02in (51.3mm)/1.6in (40.6mm) valve diameter high-performance 327 double-hump '186 and 461 heads, pushrod guide plates, hardened 'blue-stripe' pushrods, edge-orifice lifters to keep more valvetrain oil in the crankcase for high-rpm lubrication, and stiffer valvesprings. 800 plus horse power. This was the second U.S.-built production V8 to produce one horsepower per cubic inch, after the 1956 Chrysler 300B.[19]. Future 283 blocks were cast to accept the 3.875 bore. ( 7 ), Estimated Ship Date: MH Sub I, LLC dba Internet Brands The engine was also popular in Formula 5000 racing around the world, especially in Australia and New Zealand where it proved more powerful than the Repco-Holden V8. Introduced in 1978, the LG4 was essentially an LG3 with the addition of a 4-bbl carburetor and larger valves. This is a custom order part. The 265cuin (4.3L) V8 engine was bored out to 3.875in (98.43mm) in 1957, giving it a 283cuin (4.6L) displacement. It used an EFI system with electronically controlled injectors, which were mated to a twin barrel "carburetor" body. At its core was the stout L69 shortblock and it used the same aggressive L69 camshaft profile. Cole's design borrowed the valve train design scheduled to be used at the time in the Pontiac V8. The compression ratio of the L48 was lowered to 8.5:1 in 1971. In 1969, the 302 shared the finned cast aluminium valve covers with the LT-1 350 Corvette engine. In 1966, Checker began offering the 327 as an option. See how they compare in horsepower, torque, and other technical specifications. Corvette and F-bodies (Camaro IROC Z or Trans Am). Towards the end of the HQ series in 197374, due to US emissions regulations, the performance of these engines had dropped to the same or lower than Holden's locally manufactured 308cuin (5.0L) V8, which was not yet subject to similar regulations, so Holden discontinued using the engine. The LS9 was GM's 350 cubic inch truck engine used in C/K/G 10/20 models under 8,500lb (3,856kg) GVWR (gross vehicle weight rating). The preproduction LT5 initially produced 385hp (287kW), but was reduced to 375hp (280kW) and 370lbft (502Nm) for the 1990-1992 Corvette ZR-1. if ordered today, Crate Engine, Dressed Long Block, Chevy, Small Block, 396 Stroker, SBC, 350 Crate Motor, BluePrint Heads, 5.0 out of 5 stars This engine used the TBI throttle body fuel injection, which was a hybrid between EFI and carburetor technology. You can also decide how much finishing and customizing you want to do: A short block includes a balanced rotating assembly and little else. Corvette blocks had four-bolt main caps, while most other blocks were two-bolt main caps. Unless specifically noted to the contrary herein, vehicles equipped with Chevrolet Performance parts that are emissions-related may not meet U.S., Canadian, and state and provincial laws and regulations relating to motor-vehicle emissions. The 305 was sold as a crate motor under the Mr. Goodwrench brand as a replacement motor and as a boat engine for Mercury Marine until late 2014 when it was discontinued. It was intended to fill the gap where the venerable 283 and 307 had been. It was replaced by the 4.8L Vortec 4800 LR4 for the 2003 full-size vans. Overheating and damage are likely if head gaskets or heads without 'steam' holes are used on a 400 block. The L83 added "Cross-Fire" fuel injection (twin throttle-body fuel injection). It was also installed in many Isos, until 1972 when General Motors started demanding cash in advance and the Italian manufacturer switched to the Ford Cleveland V8.[22]. In 94 the LT1 switched to a mass airflow sensor and sequential port injection. The 283 had a 3.875 inches (98.43mm) bore. The 267cuin (4.4L) had a low 8.3:1 compression ratio.[33]. The 267 also saw use in 1980 to 1982 Checker Marathons.[32]. Terms of Use | Privacy and Security | Site Accessibility The LB9 was also available in the '87-92 GTA and Firebird Formula.
