Chevrolet owns the Duramax engine and design. They produce the engines. The original design, LB7 engine code (years 01-04), was purchased from Isuzu.
The Duramax is a General Motors diesel v8 engine. There are five types of Duramax engines: LB7, LLY, 2006 LLY, LBZ, and LMM. The 8th number on the VIN number will identify the engine type.
If it was an earlier 2004 truck with the Lb7 duramax (8th digit of VIN would be 1) then it has 300hp. If it was a later 2004 truck with the LLY duramax (8th digit of VIN would be 2) then it has 310hp.
LB7=520 LLY=605 LBZ=650 LMM=660 all are in lb-ft
depends on which engine you have. 2004 was the transition year. look at the eighth digit in your vin # if its a "1" you have a LB7, if its a "2" you have a LLY. LB7 300hp 520ft tq LLY 310hp 605ft tq
Lb7=01-04.5 lly=04.5-05 lbz=06-07 lmm=08-10 lml=11-??
(Lb7) 300 (LLY) 310... 320 on LLY's put in trucks in 2006-2007 (LBZ) 360 (LMM) 365
wow that is a hard question
