6.8L, 416ci, EFI, VVT, DBW, all forged internally, all aluminum motor
This came off my airboat, with only 374 hours of use. Motor is 2011, serial number 1114. Sold the aluminum airboat hull, kept the motor. My shop opened the motor, checked everything, and installed new Clevite 77 bearings (main and rod) while we were in there. They just finished it this week. Motor is complete and in perfect condition with perfect compression and no use since, except for the bench start seen in the short video. Reliable drive-by-wire setup, ready to install.
