Later in the model year, its availability was expanded to the and. During that time, the recreational marine community's small-block V8 platform of choice shifted to the 350 cu in 5.
Ten years of manufacture was punctuated by several design changes, some small or larger. In mid-1997, the Explorer and Mountaineer 5. If doesn't get that hot, it doesn't have a thermostat installed.

They also had smaller 59-61 cc combustion chambers for added compression, and the combustion chamber shape was revised to put the spark plug tip near the center of the chamber for a more even burn.

The K-code HiPo engine was an expensive option and its popularity was greatly diminished after the became available in the Mustang and Fairlane lines, which offered similar power at the expense of greater weight for far less cost. The combustion chambers also featured a smaller quench design for a higher compression ratio and enhanced flow characteristics.
