I have a 2003 Chevrolet 2500HD with a 6.0 and was curious if it is an LS based engine or if it is something completely different.

Thanks

Well yes, its a 3rd Generation small block if that's wondering.

 

I was just looking to do some top end work whenever i freshen the bottom end and was wondering what others had come up with as far as parts go, Cam, Rockers, Heads...

 

There are endless Heads&cam combinations out there. What are your goals and plans for the truck??

 

It will mainly be a daily driver while every other weekend or so it will be pulling a 13000 pound racecar trailer. It has no acceleration right now. Grandma walks off and leaves me. Basically wanting lots more horsepower and torque.
