B and RB engines are often referred to as 'wedge' engines since they use wedge-shaped combustion chambers; this differentiates them from Chrysler's 426 Hemi big block engines, which are typically referred to as 'Hemi' or '426 Hemi' due to their hemispherical shaped combustion chambers. Design features include 17 capscrews per cylinder head, a cylinder block that extends 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 external oil pump driven by the camshaft. The 'B' series wedge engine was introduced in 1958 with 332 and 355 cubic inch versions; the 362 would last until the end of the series, albeit for trucks only. The RB (“raised B”) arrived just one year after the launch of the B series engines, with 371 and 391 displacements. Unlike the previous B-engines, which had a 3.375-inch stroke, . For 1958, a “ram induction” system increased the 407's torque up to 485 lb-ft on the Chrysler 300F, trumping the old 392 Hemi by a good margin. The last 'B' wedge headed engine was produced in August 1980, ending the history of Chrysler Corporation big-block engines, however due to its popularity with hot-rodders, racers, and enthusiasts, complete B engines can now be built using entirely new parts, which are available from aftermarket manufacturers and Mopar parts division. ==B engines== All Low Block B-series engines have a stroke, a 10.0 inch deck height and 6.375 inch long connecting rods, resulting in a 1.94:1 rod ratio. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chrysler B engine」の詳細全文を読む スポンサード リンク
