Revenge of the Killer 6.0L Power Stroke
Inside an 833hp Cummins and Duramax fighter—that blows no head gaskets
Text By Jason Thompson, Photography by Mike McGlothlin
Every smoke cloud has a silver lining. This is true with the initial doom and gloom that surrounded the 6.0L Power Stroke when it first entered the market back in 2003. Diesel Power is adamant in pointing out just how good this engine can perform if its issues are addressed. Another reason we like to jump on the 6.0L bandwagon is these trucks are getting cheaper every day because many turn their nose up when they see one for sale. A few companies, such as Maryland Performance Diesel, recognized the 6.0L’s potential and decided to not throw the baby out with the leaking coolant water. Instead, it’s embraced the challenge of making the underdog 6.0L compete with the mainstream Cummins and Duramax engines. Former Diesel Power Challenge competitor Mike Corsilli said Maryland Performance Diesel’s shop truck Whitey is its fastest fuel-only rig. The 6.0L has run a best of 10.43 seconds at 127 mph in the quarter-mile (backed up with a 10.46 run).
