The Magnum 5.9 Liter OHV SMPI V8
Built in Newark, Delaware, the hallmark of the Durango is the 245-horsepower, 335 ft.-lb. of torque, 5.9-liter Magnum V-8 engine, the biggest in its class. The 5.9-liter Magnum V-8 delivered a segment-best 7,300 lbs. maximum tow rating when equipped with an optional Class IV hitch - more than some of the full-size SUVs.
Gas mileage, however, was barely better than a full-sized Suburban like the one from GM. This engine came with a four-speed automatic transmission.
The new block has roller lifters, with a new lifter angle, and has bosses for the lifter retainers. The heads are high-swirl / high-flow heads, and the Magnum has a better intake. Some changes were made to commonize the 5.9 engine.
The Magnum block is physically the same as the earlier LA engines, except the oil passage for the shaft mounted rockers is not drilled, because the Magnum engine oils through the push rods. The boss is there if you need to use the old style heads.
In 1996, as Dodge moved to the JTEC powertrain computer, the LA engine series gained OBD II on-board diagnostics, and EGR was dropped (late in the year for the 360).

The Magnum 5.9 L is an evolution of the aging 360 LA series. It got the Magnum name with new manifolds, heads, and multiport fuel injection, new cylinder heads which use a different oiling system, individually mounted rocker arms, and a CCW rotation water pump with a much improved housing.
Standard engine output was 245 hp (183 kW) and 335 lb·ft . The engine eventually produced 250 hp (190 kW) and 345 lb·ft on the version used in the Durango RT.
With the 5.9-liter engine and 3.92 axle, it's capable of pulling a 7,550-pound trailer.Chevy's Tahoe of that year was rated to pull 7,900 pounds, and Ford's Expedition was rated for 8,900 pounds. Ford's larger-for-2002 Explorer could pull a maximum of 7,300 pounds.
The 5.9-liter Magnum V8 was at the time a $595.00 option, well worth the price.
