How much horse power and how torque dose a 6.6 durmax desile have
The 6.6 liter Duramax debuted in 2001 and has been reborn three times; the numbers changed every time. Peak numbers of each incarnation are:
2001-2004: Duramax LB7 300hp, 520lb-ft.
2004-2006: Duramax LLY 310hp, 605lb-ft.
2006-2007: Duramax LBZ 360hp, 650lb-ft.
2007.5- 2010: Duramax LMM 365hp, 660lb-ft.
2011-2013: Duramax LML 397hp, 765lb-ft.
The “Big Three” all have their own diesel engine moniker: GM uses Duramax, Ford uses Power Stroke and Chrysler (MOPAR) uses Cummins.
