Tommorow we are picking up our new tow vehicle/here there driver. we are trading in the jeep and picking up a 2003 yukon denali xl 7 passenger fully loaded nav heated seats etc...

<-- Jealous! I've wanted a Denali for a while now! Dont go swapping the 6.0 into the camaro now! lol

I did think about swapping motors lol

Thats the main reason I wanted a denali was for the 6.0.. towing with the 5.3 must blow balls.

Nice! Ouch on gas though, but good if you need it for towing.

Most people I talk to would rather have the 5.3 than the 6.0. I always liked the denali's

congrats bud...looks like a killer ride

Just curious but why? Aside from some MPG the 6.0 is better?

What's wrong with a 6.0?

The little extra power isn't worth the terrible gas mileage. The 5.3 is a very strong motor.

Theyre both strong, heck theyre the exact same motors less the bore sizing. But I like the 6.0

I don't know why but a lot of my customers say that.

More HP please.

the 5.3 gets better gas mileage in the smaller vehicle but towing and in a vehicle this size since this is the xl they would suck gas big time. with a tune I should be around 18mpg on the highway which is what my jeep does anyways lol

also thanks all I really wanted a truck but compromised with the wife lol

you wont get that with out towing. My father's sierra denali gets 15 with exhaust intake a nd a efi live tune. Towing Adams gto to the track on an 18 foot open car trailer i was getting about 12.5
