Why does the 1500 6.2L V8 have more HP than the 6.6L LMM?

I just saw a commercial for the new GMC 6.2L V8 with 402 HP. I have been wondering why the 2500HD doesn't have the most HP...

The 1500 is a half ton and the 2500 is supposed to be the beast, and the beast needs a big a$$ engine, IMO.

I assume it has less torque but I just thought I'd ask you guys.

It doesn't have the neck-snapping torque that the Duramax has - only 417 foot-pounds vs. 660 for the LMM

My mothers escalade has that motor and thats a bad son of a b***h. Even though it has more horsepower, my lmm still does laps around it lol.

Exactly, the torque is where the diesel shines. Throw 15000lbs on both of them and see who wins.

So it sucks you into the seat huh? sweet......

who cares about HP...torque is where it is at. Besides you can get and extra 100 hp and nearly 200 lb/ft of torque for way less than what it would cost a gas engine to do it and you can go back to stock quick too. (not that you will once u get the feel of the higher power)

Doesnt the 2500 have the 8.1L (496ci) gas motor?

Not anymore. I think they stopped using the 496 in 2006. I had one and it really liked to guzzle gasoline. Good motor, tons of power. The 6.0 Vortec is gutless so I guess they had to do something.

I believe they stopped production of that motor!

I dont think that they are using the 8.1L anymore but it really was a MEAN gaser
