Hey Guys,

New to the scene. Just wanted to know if the horsepower numbers and torque numbers that are posted for the 2007.5 LMM are true. I have been dealing on an 07 duramax because I heard that the 2007.5 would be coming out with less HP and torque. Can anyone confirm this. If this is true I will wait till the new Duramax comes out.

Thanks for any help.

New 2007.5 Duramax with the LMM diesel will have MORE power than the current 2006 and 2007 LBZ.

Power numbers on the LMM as follows:

Horsepower: 365 HP
Torque: 660 Foot Pounds



Power numbers for the LBZ as follows:

Horsepower: 360 HP
Torque: 650 Foot pounds.



*5 Hp and 10 Foot pound increase from LBZ to LMM.

Hope that clears things up a bit for you.;)

those are the same numbers that i have seen.
