Magnum engines
The LA family was updated and branded as the Magnum V6 and V8 in 1992. While the Magnum 3. 9, Magnum 5. 2, and Magnum 5. 9 engines were significantly based on the 239, the 318, and the 360 — respectively — many of the parts will not directly interchange. Magnum cylinder heads use a different oiling system. The intake manifolds share dimensions but will not interchange without modifications. Chrysler's engineers redesigned the oil seals on the crankshaft to improve anti-leak seal performance. Although the pre-Magnum and Magnum versions of the 360/5. 9 are both externally balanced, the two are balanced differently and each requires a uniquely balanced flywheel or torque converter. The valve covers on the magnum have 10 bolts rather than the previous 5, for improved oil sealing.
Chrysler offered a line of crate engines based on the Magnum designed to bolt into older muscle cars and street rods with little modification Some of the changes to facilitate this were using a 1970-93 water pump so that older pulleys and brackets could be used, as well as an intake manifold that uses a carburetor instead of fuel injection.

Production of the LA series was long handled by the Mound Road Engine factory in Detroit, Michigan. Mound Road Engine was a Chrysler Corporation Automobile engine factory in Detroit Michigan. With most versions cancelled, that plant was closed in 2002.
273 V8
The 273 (4. 5 L) was the first LA engine, introduced in 1964 and offered through 1969. It had a 3. 625 in (92 mm) bore and 3. 31 in (84 mm) stroke. It had a mechanical solid lifter valvetrain until 1968 when hydraulic lifters were introduced. A special high-performance version of the 273 was created in 1966. It used a 0. 500-inch (12. 7 mm) lift solid-lifter camshaft, steel-tube title exhaust, and a Holley 4-barrel carburetor, producing 275 horsepower (1 hp/in³). It was available in the Dodge Dart only, and the car so equipped was called the "D-Dart". The Dodge Dart was an automobile built by the Dodge division of the Chrysler Corporation from 1960 to 1976 A 235 hp (175 kW) version with a less aggressive camshaft and without the tube titles was available on regular production Darts, Valiants, and Barracudas starting in 1965. The Plymouth Valiant is an Automobile manufactured by the Plymouth division of Chrysler Corporation in the United States from 1960 to 1976 The Plymouth Barracuda is a car that was manufactured by the Plymouth division of the Chrysler Corporation from 1964 through 1974

The Chrysler A engine is a Small-block V8 Automobile engine from Chrysler Corporation. Like the A 318, it has a larger bore at 3. 91 in (99 mm) as well as a stroke of 3. 31 in (84 mm). It appeared shortly after the 273, in 1967, and proved tremendously successful. A version of this engine was available until 2002 when its production ceased. It used hydraulic lifters and a two barrel carburetor for most of its production, though four-barrel Carter Thermoquad and Rochester Quadrajet carburetors were used in police applications starting in 1978. A carburetor (North American spelling or carburettor ( Commonwealth spelling) is a device that blends air and Fuel for an Internal The 318 received roller lifters and a fast-burn cylinder head in 1985, and throttle-body electronic fuel injection for truck applications starting in 1988.

The Magnum 5. 2, released in 1992, was an evolutionary development of the 318 with the same displacement. The Magnum development included the multiport fuel injection, new cylinder heads with a closed combustion chamber, a new higher-flow valve angle, increased valve lift, and new intake and exhaust manifolds. Fuel injection is a system for mixing fuel with air in an Internal combustion engine. Power was up to 230 hp (170 kW) and 300 lb·ft (410 N·m). Production of the Magnum 5. 2 ended with the 2003 model year Dodge Ram Van. The Dodge Ram Van was a Full-size Van marketed under the Dodge brand by the Chrysler Corporation and later DaimlerChrysler It was replaced by the new 4. 7 L PowerTech V8. The PowerTech was a new engine family for Chrysler, and was not based on the Chrysler A engine as existing Chrysler V8s were
340 V8
As the Detroit power wars heated up in the mid-1960s, Chrysler decided to produce a small block V8 specifically designed for high performance applications. The Dakota is a Mid-size Pickup truck from the Chrysler LLC 's Dodge brand This article is about the full-size truck For other uses such as the full-size van see Dodge Ram (disambiguation. The Dodge Durango is a full-size SUV from Chrysler 's Dodge brand The Dodge Ramcharger was a large Sport utility vehicle built by Dodge from 1974 to 1993 and based on a shortened-wheelbase version of the Dodge D Series The Dodge Ram Van was a Full-size Van marketed under the Dodge brand by the Chrysler Corporation and later DaimlerChrysler The Jeep Grand Cherokee is a Mid-size unibody Sport utility vehicle produced by the Jeep division of Chrysler. The goal was to have a lightweight, high output engine equally suited for the drag strip or an oval track. The result of this decision was the 340 in³ V8. Chrysler's engineers increased the 318's cylinder bores to 4. 04-inch (103 mm) while keeping the 318's 3. 31-inch (84 mm) stroke. Anticipating higher loads resulting from racing operation, the engineers fitted a forged steel crankshaft instead of the cast nodular iron unit used in the 318. A 4-Barrel carburetor was mated to a high-rise, dual plane intake manifold. This induction setup fed into a set of cylinder heads that are still considered one of the best of that era. The heads were high-flow items with big ports, and used 2. 02-inch (51 mm) intake and 1. 60-inch (41 mm) exhaust valves. An aggressive cam was fitted to take advantage of the much better breathing top end. 1968 4-Speed cars got an even hotter cam, but it was discontinued in 1969. The engine was equipped with hydraulic lifters. Power output was officially stated as 275 hp (205 kW) for the 4 barrel and 290 hp (216 kW) for the 6-pack version with triple 2-barrel carburetors. Using flat-top pistons, the 340's compression ratio was 10. 5:1, placing it near the limit of what was possible on pump gas. The 340 also used heavy-duty parts such as a dual timing chain, windage tray and revised oil pump.
In 1970, Chrysler offered a special version of the 340 for use in the Challenger TA and Cuda AAR. The "TA" engine featured a heavy duty short block featuring additional webbing in block to allow for 4 bolt main bearing caps, double roller timing chain and 10. 5:1 compression. The heads featured larger ports compared to a standard 340 and offset rocker arms that allowed the pushrods to be moved away from the intake ports for improved airflow. They featured an aluminium intake manifold with three two barrel Holley carburettors and a dual points ignition system.
Like many other performance V8's of the day, for insurance reasons, the 340 engine's power output was officially understated. In reality, either the 4bbl or 6bbl configuration could produce at least 315 to 320 hp (235 to 239 kW). The 340 developed a reputation for outperforming much larger and heavier engines, with the attendant handling benefits provided by the relatively light-weight 340. The engine was praised as a high-revving unit with good durability, making it popular with circle-track racers.
Due to the combination of rising gas prices and insurance company crackdown on high-performance vehicles, the 340 did not stay in production long. It was released in 1968, detuned with lower compression and smaller 1. 88 inch intake valves in 1972, and was withdrawn from production after the 1973 model year.
360 V8
The LA 360 (5. 9 L) has a 4. 00 in bore and a 3. 58 in stroke. It was released in 1971 with a two barrel carburetor. A carburetor (North American spelling or carburettor ( Commonwealth spelling) is a device that blends air and Fuel for an Internal The 360 used the large intake port 340 heads with a smaller intake valve (1. 88 inch). In 1973, a 4-barrel version was released. In 1974, the 360 became the most powerful LA engine with the end of 340 production. After 1981, the 360 was no longer used in cars, but only in the Dodge Ram trucks and vans.

The Dodge B-series was a full-sized passenger and utility van built by Chrysler Corporation, which replaced the previous smaller A-series Compact The 1978-1979 Lil' Red Express truck used a special high performance 360 4-barrel engine, with factory production code EH1{[fact}}. The EH1 was a modified version of the E58 360 police engine (E58) producing 225 hp (168 kW) net @ 3800 rpm. Some prototypes for the EH1 featured Mopar Performance W2 heads, although the production units had the large-valve 360 heads. The 360 was replaced for 2004 with the 5. 7 L Hemi.

The 3. 9 L (238 in³) V6, like the 5. 2 and 5. 9 V8s, received the new Magnum cylinder heads, induction and engine management system as well as the Magnum name in 1992. Power increased substantially to 180 hp (134 kW)and from 195 lb·ft (264 N·m) to 220 lb·ft (298 N·m). In 1994 the exhaust manifolds for this engine were reduced in size to save money. This reduced the engine's output to 175 hp (130 kW), but it retained its torque rating which later grew to 225 lb·ft (305 N·m). This engine was last produced for the 2003 Dodge Dakota pickup.

The first-generation Viper V10 engine has a displacement of 8. 0 L (488 in³) and produces 400 hp (298 kW) and 490 lb·ft (664 N·m). The second-generation engine, also displacing 8. 0 L, produced 450 hp (336 kW) and 490 lb·ft (664 N·m). The third-generation engine, introduced on the 2003 Viper, has a piston displacement of 8. 3 L (505 in³) and produces 510 hp (380 kW) and 535 lb·ft (725 N·m). On January 8, 2007 Dodge released information at the Detroit Auto Show that the 2008 Dodge Viper engine's output would increase to 600 hp (447 kW) and 560 lb·ft (759 N·m) via a slight displacement increase to 8. 4 L (510 in³) and the use of variable valve timing.
Production of the V10 engine started at Mound Road Engine before moving to Conner Avenue Assembly, where the Viper itself is built, in May 2001. Mound Road Engine was a Chrysler Corporation Automobile engine factory in Detroit Michigan. Conner Avenue Assembly is a Chrysler Automobile factory in Detroit Michigan. In addition, the Viper V10 was installed in the Dodge Ram SRT-10, earning the truck the Guinness World Record for fastest production truck (later bettered by an Australian production car; the Holden HSV Maloo that uses the LS2 Corvette engine).

Magnum V10
Originally conceived in the 1980s as a truck engine for the larger Rams, the Magnum V10 was re-engineered as the engine of the Dodge Viper in 1990 by Lamborghini, then owned by Chrysler, and used in the Ram 2500 starting in the 1994 redesign of the Ram line. It provided far less power than the V10 in the Viper. Output was 300 hp (220 kW) and 400 lb·ft (540 N·m).
