6L90, been very impressed so far. When towing my wife's Trans Am I was surprised that I didn't have to brake nearly as much as I did with my 2000 Silverado 1500.

For a daily driver and my requirements it clearly exceeds.

I was talking about a lift and my wife said "Why would you lift it? I can barely get in it now. I wouldn't be able to drive it then!" I replied "...but you could still wash it, right?"

 

front mount 6.0 HD > duramax IMO

nice truck for sure

 

Front mount 6.2 > front mount 6.0

sorry had too lol
(planning/saving for a KB setup for mine)

I think it's dumb that gm offers a 6.2 1500 but only a 6.0 2500... I mean it worked out for me but it doesn't make any sense!

 

My take on the 6.0 for the HD's . . .

The 6.2 is a higher compression engine (Premium Fuel Recommended) and has an aluminum block.

Most HD truck buyers don't / won't use anything other than 87 octane fuel, and the iron block is more durable in high GVW applications.
