Happy 2019! Lets start off the year by continuing our series on the best big truck engines available on the market right today, and now we’re going to tackle the 6.2L Ford BOSS V8 engine.
BOSS is the internal name of the 6.2L V8 engine available in the Ford Super Duty trucks, and the previous generation Ford F-150 and Raptor. The BOSS engine comes from a long legacy of Ford Modular engines ranging from the 4.6L V8 found in everything from Crown Victoria’s and F150’s to the 6.8L V10 engine found in the Ford Super Duty pickups, E-series vans and medium duty trucks. These similarities encompass things like a deep-skirt block for rigidity, cross bolted main bearing caps, crankshaft driven gerotor oil pump, OHC (overhead cam) cam arrangement and an SAE standard bell housing bolt pattern.
Introduced in 2010, the 6.2L has been built at Ford’s Romeo Engine plant in Romeo Michigan. The Design is a two-valve per cylinder single overhead cam (SOHC) per head design, departing from Chrysler and General Motors use of cam-in-block OHV pushrod configurations. Roller-rocker camshafts, dual equal variable cam timing and dual spark per cylinder gives the engine a high operating speed, and capacity to move plenty of air to breathe.
In its HD inception, the engine produced 385 horsepower and 405 lb-ft of torque. Its raptor variant produced a further 411 horsepower and 434 lb-ft of torque. In 2017, in an attempt to dethrone the 6.4L HEMI, Ford revised the cam profile to produce an additional 25 lb-ft of torque for a total of 430, giving it class leading gasoline engine torque for the medium duty truck segment.
The rumor mill has been churning as of late with the 6.2L BOSS’s replacement on the horizon. Current speculations are a DOHC 7.4L direct injected V8 to be introduced with the 2020 Super Duty refresh, mated to Ford’s new 10-speed HD automatic transmission.
