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]
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 ...
Cylinder block material: Cast iron: Cylinder head material: Cast iron: Valvetrain: Cam-in-block 2 (B-Series) or 4 (ISB, QSB) valves/cylinder: Compression ratio: 17.2:1, 17.3:1, 17.5:1, 19:1: Combustion; Turbocharger: Holset Engineering (variable) Fuel system: Common rail high pressure direct injection, symmetrical combustion chamber with 7-hole ...
In 1958, Chrysler introduced its new wedge-head B Block engine, which was implemented in the Dodge and DeSoto lines. The following year saw the introduction of the RB Block in Chryslers and Imperials; this was a modified B Block with a raised deck resulting in an increase of stroke from 3.18 inches to 3.75 inches. In 1960 and 1961, Chrysler ...
Although the modernized 390 series engine was compact and light for its displacement and output, 429 cu in (7.0 L) represented the limit of the original architecture's expansion, and it had been surpassed by Chrysler's 440 and Lincoln's 462 and 460. Cadillac went bigger, with provision for even more expansion.
A dyno that is coupled directly to an engine is known as an engine dyno. A dyno that can measure torque and power delivered by the power train of a vehicle directly from the drive wheel or wheels without removing the engine from the frame of the vehicle), is known as a chassis dyno.
