273 V8

The 273 (4.5 L) was the first LA engine, introduced in 1964 and offered through 1969, rated at 180 BHp. 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 version was also available in 1966 only - it used a 0.5 inches (12.7 mm) lift solid-lifter camshaft, fabricated-steel-tube exhaust, and a Holley 4-barrel carburetor, producing 275 horsepower (1 hp/cu in).

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 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 cu in V8. Chrysler's engineers increased the 318's cylinder bores to 4.04 inches (102.6 mm) while keeping the 318's 3.31 inches (84.1 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 inches (51.3 mm) intake and 1.6 inches (40.6 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 for the 4 barrel and 290 hp for the 6-pack version with triple 2-barrel carburetors. Using domed pistons, the 340's compression ratio was 10.5:1, placing it near the limit of what was possible on pump gasoline. The 340 also used heavy-duty parts such as a double-roller 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 carburetors 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 gasoline prices and insurance companies' crackdown on high-performance vehicles, the 340 did not stay in production long. It was released in 1968, detuned with lower compression (via flat-top pistons) and smaller 1.88 inch intake valves in 1972, and was withdrawn from production after the 1973 model year.

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 (1993-up) engines were significantly based on the 239, the 318, and the 360 — respectively — many of the parts will not directly interchange and are not technically LA engines (the only parts that are actually unchanged are the crankshafts and connecting rods). Magnum cylinder heads use a different oiling system and individually mounted rocker arms (AMC style) and a CCW rotation water pump with a much improved housing. The intake manifolds share basic 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 ('71-'92) and Magnum versions of the 360/5.9 are both externally balanced, the two are balanced differently (the 360 Magnum uses lighter pistons) and each requires a uniquely balanced damper, flywheel, drive plate, or torque converter. The valve covers on the Magnum have 10 bolts rather than the previous 5, for improved oil sealing.

. Prototype blocks were cast by Lamborghini, at the time a Chrysler division. Some felt that the pushrod two-valve design, while adequate for the truck application for which the engine was originally created, was unsuitable for a performance car. However, Chrysler was uncertain about the Viper's production costs and sales potential and so declined to provide the budget for the modification.

The first-generation Viper V10 engine has a displacement of 8.0 L (488 cu in) and produces 400 hp and 465 lbft. The second-generation engine, also displacing 8.0 L, produced 450 hp and 490 lbft. The third-generation engine, introduced on the 2003 Viper, has a displacement of 8.3 L (505 cu in) and produces 500 hp and 525 lbft. 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 and 560 lbft via a slight displacement increase to 8.4 L (510 cu in) and the use of variable valve timing, among the first utilized in a pushrod 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 Chrysler Engineering, and used in the Ram 2500 starting in the 1994 redesign of the Ram line. When the 8 L 488ci V10 Magnum debuted for the Dodge Ram 2500 & 3500 in 1994, it was the most powerful gasoline engine available for consumer pick-ups. It provided far less power than the V10 in the Viper and used a cast-iron cylinder block. Output was 310 hp and 450 lbft. It was discontinued after the 2003 model year.
