This design dates back to 1940, when it was introduced in the Nash 600 as an L-head 172.6 cu in (2.8 L) engine. Displacement was increased over the years to 184 cu in (3.0 L), and finally to 195.6 in the early-1950s. The block casting was changed to allow an OHV head for the 1956 Rambler (the L-head was discontinued).
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. The first three digits of the casting number on the large chamber heads are 321, 322, or 323 depending on year. The only difference between small and large chamber Gen-3 heads is the combustion chamber size.
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 is not the same as Chrysler's 360 V8. [4] Chrysler continued production of the AMC 360 engine after the 1987 buyout of AMC to power the full-size Jeep Wagoneer (SJ) SUV that was produced until 1991. [5] It was one of the last carbureted car/truck engines built in North America. [6] Chrysler never used this engine in any other vehicle.
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 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 ]
The Chrysler 3.3 and 3.8 engines are V6 engines used by Chrysler from 1989 to 2011. This engine family was Chrysler's first 60° V6 engine designed and built in-house for front wheel drive vehicles, and their first V6 not based on a V8.
