Interesting, I haven't heard any rumors or information about the displacement changes on the 5.3 and 6.2; along with nothing new about the 8.3 diesel.

 

I wonder if the 6.6 currently in the HDs will be moving down to the light duty, which would be odd because all the tuning and engineering done on that engine was not done for the light duty consumer.

I dont have info on the details of the 6.6 in the 1500's other than the displacement and it will have AFM/DFM crap on it and likely a sizeable EGR so if its the same as the one used in the HD it will ruin all that makes the L8T good. 

The 5.3 and 6.2 are gone, not just changed. 

The 8.3 Duramax is entirely new and will have changes to the charge air cooler system along with other items.

Both the Chevy and International versions of the joint venture trucks use the current Duramax. 

I believe it is detuned from the pickup application. Thats been common for the Dmax in applications other than pickups.

Yes but it is a different RPO code due to there being a smaller turbo, different fuel injectors and different state of tune. 

 

Prior generations carried the same RPO code as the pickups and de-tuned but LBZ was skipped.  They used the LB7 2003-2004, the LLY 2004.5-2006 and then went straight to LMM for 2007-2009.

My pet peeve is the 'chrome' inlay in the floor trim for the front doors. I can see if a person isn't careful w/ their boots getting in & out they will be scraped up in no time.

 

Does GM's braintrust not know that some of us use them as trucks, not cars?
