Chrysler LA Engine - Big Power: The 8.0L Magnum V10

Big Power: The 8.0L Magnum V10

As the design for the 5.2L Magnum V8 was coming together in 1988, consideration was given to the design of a larger V10 iteration, mainly intended for use in Dodge Ram 2500 and 3500 pickups. This was to be Chrysler's first 10-cylinder engine, and can best be understood as a 5.9L V8 with two cylinders added. This 488-cubic-inch engine was based on a cast iron block, and was rated for 310 hp (230 kW) @ 4,100 rpm and 450 lb·ft (610 N·m) torque @ 2,400 rpm. Bore was 4.00" and stroke was 3.88"; compression ratio was 8.4:1; firing order was 1-10-9-4-3-6-5-8-7-2. Valve covers were die cast aluminum, rather than stamped steel; this lowered noise levels and made for better gasket sealing.

The 8.0L Magnum V10 first became available in the 1994 model year Dodge Ram 2500 and 3500 pickups, and it was the most powerful gasoline-burning engine then available in any passenger pickup truck. The engine lasted through the 2003 model year, after which it was discontinued.

Famous quotes containing the word big:

    Whenever there’s a big war coming on, you should rope off a big field. And on the big day, you should take all the kings and their cabinets and their generals, put ‘em in the center dressed in their underpants and let them fight it out with clubs. The best country wins.
    Maxwell Anderson (1888–1959)
