by Justin Cupler

The 360 engine was a staple in Dodge's lineup through the 1960s and 1970s. It reappeared again in the mid-1990s through early-2000s. In 1978, four different versions of the Dodge 360 were available.

Configuration

Two of the four versions of the 360 engine were fitted with a two-barrel carburetor: E57 and E59. Two also were fitted with a four-barrel carburetor: E56 and E58.

Internals

The bore (cylinder width) of 4 inches, stroke (distance piston travels inside the cylinder) of 3.52 and 8.4:1 compression ratio remained common through all of the versions of the 360. The bore and stroke combined to create the total engine displacement of 360 cubic inches.
