Anyone hearing anything more about the possiblity of a GM V10 or possible changes in the 8.1 V8.

Last I heard, the GM V-10 was scrapped for a higher performance (possibly Super charged) V8. Time will tell, official news has not been released yet and for MY07, you won't know until next year.

i got this from the LLY fourm so i dunno if it is true or not


GMT-900 pickups will receive the Atlas 6 standard. It will likely have a power output of 290HP with 300lb/ft of torque. Optional engines will include the 4.8L V8 with 300HP and 335 lb/ft of torque... The power numbers for the new 5.3L Vortec will be 355HP and 380lb/ft of torque. The L33 version of the 5.3L V8 will have 370HP and 385lb/ft of torque... The 6.0L Vortec will jump in power to 400HP and 400lb/ft of torque... The LQ9 version of the Vortec 6000 will put out 435HP and 440lb/ft of torque. The 8.1 will return with extra power as well increasing HP from 330 to 375 and pumping up torque from 450 to an amazing 480! To top it all off, the Duramax 6600 will increase power from 310HP and 605lb/ft of torque, to 345HP and an earth shattering 630lb/ft.

But listed above is the info for the MY06 models. Still waiting for the MY07 information.

Check out gminsidenews.com. There are a couple threads on there about the motors. There is a pic on there of what the 06 1/2tons will look like as well.
