1974 was the only year that the 360 4 barrel was in the Cuda
Some Engine history:
The LA 360 (5.9 L) has a 4.00 in bore and a 3.58 in stroke. It was released in 1971 with a two barrel carburetor. The 360 used the large intake port 340 heads with a smaller intake valve (1.88 inch). In 1974, with the introduction of the code E58 4-BBl dual exhaust version (at 245 SAE net horsepower) became the most powerful LA engine with the end of 340 production.
Power started dropping from 1975 on as more emission controls were added resulting with the 1980 E58 engine only producing 185 SAE net HP. Starting with 1981, the 360 was exclusively used in Dodge trucks and vans.
The 1978-1979 Li'l Red Express truck used a special high-performance 360 4-barrel engine with factory production code EH1, and was the fastest American made vehicle from 0-100MPH for those years.[3] The EH1 was a modified version of the E58 360 police engine (E58) producing 255 hp (190 kW) net @ 3800 rpm.
Some prototypes for the EH1 featured Mopar Performance W2 heads, although the production units had the standard 360 heads. Some police package cars came from the factory with a steel crank and h-beam rods.[4] There was also a "lean burn" version of the 360. The LA360 was replaced in 1993 by the 5.9 Magnum, which shared some design parameters with the LA360, however the majority of its components were different. The 5.9 Magnum was then replaced by the 5.7 Hemi.
