The 440 ‘RB” engine heritage dates back to 1958, starting with the 350 cubic inch block ‘B’ engine. The ‘B’ engine was offered over the years in displacements of 361, 383 and 400 cubic inches. In 1958 Chrysler introduced a version of the ‘B’ engine with a raised deck block, giving it a longer piston stroke. The new engine displaced 383 cubic inches and would be the first ‘RB’ engine into production. In the following years displacement was increased to 413, 426 and 440 cubic inches.

Standard engine for all years of the Dodge Coronet R/T was the 440 C.I. 4-BBl Magnum V8. The “440 Six Pack” engine was offered in 1969 – 1971. This engine featured three two-barrel Holley carburetors on an Edelbrock aluminum intake manifold. This engine was rated at 390 hp and 490 pounds-feet of torque.

The 440 ‘RB” engine was an available option on most Chryslers musclecars of the 60’s and 70’s including Charger, Challenger, Road Runner, GTX, Super Bee and more. 440’s also powered many of Chrysler, Dodge and Plymouths large cars, motorhomes and trucks. Production of the 440 ‘RB’ engine ceased in 1978.
