Editing Chrysler B engine (section)

==Design==
Design features of the B and RB engines include 17 capscrews per [[cylinder head]], a [[cylinder block]] that extends {{cvt|3|in|mm|1}} below the [[crankshaft]] centerline, an [[intake manifold]] not exposed to [[crankcase]] oil on the underside, stamped-steel shaft-mounted [[rocker arm]]s (race versions used [[forged steel]] rockers), and a front-mounted external [[Oil pump (internal combustion engine)|oil pump]] driven by the camshaft. In order to provide a lower hood and center of gravity, the engine to be mounted lower than before. Apart from changing the engine dimensions and engine mount position, this also entailed reconsidering the distributor drive and oil pump locations. The oil pump could not be allowed to extend below the crank throw to avoid interfering with the steering linkage. The engineers moved the distributor to the front of the engine, at a 45-degree angle, which cleared the heater while allowing the oil pump to be located in front of the block - above the bottom of the crank's throw, clearing the steering linkage.<ref name=RnM59/>

The 'B' series wedge engine was introduced in 1958 with {{cvt|350|cuin|L|1}} and {{cvt|361|cuin|L|1}} versions. The 361 would continue in production until the end of the series, albeit only for truck installation. The RB ("raised B") arrived one year after the launch of the B series engines, in {{cvt|383|cuin|L|1}} and {{cvt|413|cuin|L|1}} displacements. Unlike the previous B-engines, which had a {{convert|3+3/8|inch|mm|1|adj=on}} [[Stroke (engines)|stroke]], the RB engines had a {{convert|3+3/4|inch|mm|1|adj=on}} stroke.

For 1960, a "ram induction" system increased the 413's [[torque]] up to {{cvt|495|lbft|Nm|0}} on the Chrysler 300F versions.

The last 'B-RB' wedge-headed engine was produced in August 1978, ending the era of Chrysler "big-block" engines.
