Ford Boss engine

Boss is the internal name for a family of large-displacement V8 engines from Ford, intended to compete with Chrysler's Hemi and General Motors' 6.0 litre Vortec. It was first called Hurricane, development was cancelled in 2005 and revived in 2006, and after the damage of Hurricane Katrina it was renamed Boss. Ford never marketed the engines under that name in a production vehicle and referred to them by displacement. The only modern Boss engine was a 6.2 litre V8 built at the Ford Romeo Engine Plant in Michigan from 2010 until the plant closed in December 2022. It shares deep-skirt block and overhead-cam design traits with the Modular family but has much wider bore spacing, a two-valve SOHC valvetrain, hemispherical heads and two spark plugs per cylinder.
