Ford F150 EcoBoost 2018-2020

Mountune’s extensive knowledge of the Ford EcoBoost engine coupled with broad motorsport experience provides the foundation for our Premium High Performance 3.5L V6 Ford EcoBoost Closed Deck Long Block. Each short block is skillfully assembled using a brand new Ford engine block engine that has been precision machined to accept the Cylinder Support System additionally, the block's deck surface has also been surfaced for a superior finish to accept MLS gaskets. The Cylinder Support System is a proven method of strengthening open deck engine blocks while maintaining OEM integrity. It prevents cylinder cracking, walking, and bell mouthing. The support ring is made from aircraft grade 6061-T6 aluminum. We then add Mountune CP Forged Pistons, Mountune Carrillo Forged Connecting Rods and high performance bearings. This Long Block is the perfect foundation for your Raptor or F150 for high boost applications. We take the guess work out of critical engine assembly allowing you to install your existing cylinder head and other base engine components to this premium improved foundation.

The engine block is first inspected, de-burred, and the bores are honed to perfection to receive Mountune CP Forged Pistons. The rotating assembly that includes a new Ford crankshaft or optional billet steel crankshaft and Mountune Carrillo Forged Connecting Rods is balanced to within .5 gram. The select parts are professionally assembled by one of Mountune's skilled engine builders using high performance bearings.
We then install new genuine Ford cylinder head assemblies, updated camshaft phasers and complete camshaft drive assembly. Genuine Ford oil pan is also included. Each assembly includes a detailed data sheet showing all critical engine dimensions.
