mountune High Performance 3.5L EcoBoost N1 Long Block - F150 Raptor
Mountune's extensive knowledge of the Ford EcoBoost engines coupled with our comprehensive motorsport experience provides the foundation for our high performance 3.5L Ford EcoBoost long block assembly.
Each long block starts off as a brand new aluminum Ford F-150 Raptor open deck engine block which can be strengthened with the Cylinder Support System before being skillfully assembled with mountune forged pistons, forged h-beam connecting rods, tri-metal racing bearings, and a forged crankshaft all balanced to motorsport standards. We then add all new genuine Ford Gen2 cylinder heads and valve train along with the latest version cam phasers and drive chains all timed to factory specs.
