The Chrysler B and RB engines are a series of big-block V8 gasoline engines introduced in 1958 to replace the 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 426 Hemi big block engines that are typically referred to as "Hemi" or "426 Hemi ...
The Chevrolet big-block engine is a series of large-displacement, naturally-aspirated, 90°, overhead valve, gasoline-powered, V8 engines that was developed and have been produced by the Chevrolet Division of General Motors from the late 1950s until present. They have powered countless General Motors products, not just Chevrolets, and have been ...
It used a new 4.13-inch (104.90 mm) bore with the 390's 3.785-inch (96.14 mm) stroke, giving a displacement of 405.7 cu in (6.6 L), rounded up to "406" for the official designation. The larger bore required a new block casting design allowing for thicker walls, but otherwise was very similar to the 390 block. [20]
The big-block engines initially used a forged crankshaft with a stroke of 3.975" for the 1965-1967 425 and 400 CID versions; starting in 1968, both the 400 cu in (6.6 L) and the 455 cu in (7.5 L) big blocks used a stroke of 4.25 in (108 mm), with crankshaft material changed to cast iron except in a few rare cases.
Champion spark plugs provided their dyno room. Towards the end of 1968, Kaplan enlisted help from Dan Byer, a retired engineer from AMC, to develop a new block casting. Using AMC 390 engineering drawings, they added more mass for four-bolt mains and improved the oiling system. A run of 50 blocks was contracted to Central Foundries in Windsor ...
The Gen-2 is closer to the physical size of U.S.-made small-block V8s except for the bore centers, which are the same as some big-block engines. The only parts shared between the 1966-67 Rambler V8 and 1966-91 AMV8 are the lower cam timing sprocket and the timing chain. [citation needed]
