The '''Chrysler B and RB engines''' are a series of [[V8 engine#Size, layout, and classification|big-block V8]] [[gasoline engine]]s introduced in 1958 to replace the [[Chrysler Hemi engine#First|Chrysler FirePower]] (first generation Hemi) engines. The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped [[combustion chambers]]; this differentiates them from Chrysler's [[Chrysler Hemi engine#426|426 Hemi]] big block engines that are typically referred to as "Hemi" or "426 Hemi" due to their hemispherical shaped combustion chambers. The corporation had been seeking a smaller and lighter replacement for its FirePower engines, in part because new styling dictates meant moving the engine forward in the chassis which negatively affected weight distribution.<ref name=RnM59>{{cite journal | last1 = Rarey | first1 = R.S. | last2 = Moeller | first2 = E.G. | title = Chrysler Corporation's New V-8 Engine | journal = SAE Transactions | volume = 69 | date = 1959 | page = 95 }}</ref>
