Chrysler Corporation's B engine was a Big-block V8 which replaced the early Chrysler FirePower engine in 1958. It did not have hemispherical heads like the FirePower — rather it had wedge-shaped heads. All B-series engines have a 3.375 inches (85.7 mm) Stroke. Chrysler also produced a larger version, the Chrysler RB engine.

Design features include 17 capscrews per cylinder head, a cylinder block that extends 3 inches (76 mm) below the crankshaft centerline, an intake manifold not exposed to crankcase oil on the underside, stamped-steel, shaft-mounted rocker arms (race versions used forged steel rockers), and a front-mounted oil pump driven by the camshaft.

The B engine started at 350 cu in (5.7 L) and 361 cu in (5.9 L), and a 383 cu in (6.3 L) version appeared the next year. Plymouth automobile called its version of the early B Golden Commando. It produced 305 brake horsepower (227 kW). DeSoto's B engine was the Turboflash. It put out 295 brake horsepower (220 kW). Dodge's B was called the D-500 and produced 320 brake horsepower (240 kW).



The 350 cu in (5.7 L) B engine had a bore of 4.0625 inches (103.19 mm) and was only produced in 1958. It was used on the following cars:


The 361 cu in (5.9 L) B engine was similar to the 350 except for a wider 4.125 inches (104.8 mm) bore. There was a multipoint electronic Fuel injection version in 1958 only. The Plymouth version was called the Commando, variants of which included the Golden Commando and SonoRamic Commando. It was used in the following vehicles:


The 383 cu in (6.3 L) short-stroke B engine used a 4.25 inches (108 mm) bore and was introduced in 1959 for the 1960 model year. Over 3,000,000 B 383 engines were produced between 1959 and 1971.[citation needed] Dodge's version, the D500, had a cross-ram induction manifold and dual 4-barrel Carburetor as options. In some Dodge applications, this engine was labelled as the Magnum, while the Plymouth's version was called the Golden Commando. The "Golden Commando" came with a special[vague] dual-point distributor, a drag-racing derivation.

The B 383 was found on the following vehicles:


The 400 cu in (6.6 L) B engine was introduced in 1972. It shares the B family's 3.38 inches (86 mm) stroke, but is bored out to 4.34 inches (110 mm). There were standard- and high-performance options.
