2002 and earlier engines featured a one-piece cast nodular iron crankshaft with counterweights present on either side of each crank pin. A crankshaft tone wheel was present between number 1 and number 2 connecting rod pins, and was machined such that a Hall-effect magnetic pickup mounted to the engine block could read the crankshaft's position ...
The resulting engine was somewhat improved as to power and efficiency. The 5.9 L V8 engines followed suit in 1989, but also received the overall improved "308" cylinder heads (casting number 4448308) that featured significantly higher flowing exhaust ports and a return to the original 1971 (non-fast burn) combustion chamber.
It was introduced in two piston displacement sizes in 1960: The 170 cu in (2.8 L) "LG" (low-G, referring to the relatively short engine block casting and crankshaft stroke) in the Valiant, and the 225 cu in (3.7 L) "RG" (raised-G, referring to the relatively tall engine block casting and crankshaft stroke) in full-size Plymouth and Dodge Dart ...
1978–1979: 6DR5 2.5 L 6G73 - Used in the Chrysler Sebring, Dodge Avenger, Chrysler Cirrus, and Dodge Stratus; 3.0 L 6G72 - Used in the Plymouth Acclaim/Dodge Spirit and 1987–2000 Dodge Caravan/Plymouth Voyager, also Dodge Dynasty, Chrysler LeBaron, Chrysler TC, Chrysler New Yorker, Dodge Daytona, Dodge Stealth, Chrysler Sebring (Coupe), Dodge Stratus (Coupe), Dodge Shadow ES, and Plymouth ...
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 first version of this engine family was a normally aspirated 2.2 L (134 cu in) unit. Developed under the leadership of Chief Engineer – Engine Design and Development Willem Weertman and head of performance tuning Charles "Pete" Hagenbuch, who had worked on most of Chrysler's V-8 engines and the Chrysler Slant-6 engine, [1] it was introduced in the 1981 Dodge Aries, Dodge Omni, Plymouth ...
The casting was fixed in mid to late 2001, but the same casting number was retained. The "fixed" heads have "TUPY" cast in the center where the cracks used to occur. [ 37 ] Also new for the 2000 model year, was the distributor-less, coil on plug ignition system. [ 38 ]
They are commonly identified by the first three (319) or last three (291 for the 360-401 heads; 304 used a different casting) digits of the casting number. There was a U.S. auto industry-wide shift to lower compression ratios in mid-1971, so AMC increased combustion chamber size to 58-59 cc.
