I just bought a 2002 6.0L out of a wrecked 2500, I hopeing it is a LQ9 motor, they already had it removed from the truck, so how do I find out it is a LQ9? anway, I am having the block bored and made into 408 C.I. so I don't think it will matter if it is a LQ4 or an LQ9, The blocks are the same, the diff in HP, they are getting out of the tunning and the way the heads are set up

I don't think it's a LQ9 if it came out of that truck... I think the only way to tell would be to check the glove-box codes.
But yeah, if you're putting in a new rotating assembly, it won't make any difference.

I didn't want to get a 6.0L when I bought my truck because I believed the specs form GM and it seems like a waste. I was wrong. With the same mods on a 6.0L as I have on my 5.3L I would have been solid into the 13s N/A. My buddies truck weighs 500lbs more than mine and he smokes me on a daily basis with similar mods. I just can't compete with the extra cubes.

So how much hp and torque will a tune add? Also is the tune one of those programmer things? What other mods will make the motor come alive. Also this is going to be in a 3/4 ton truck. So i dont need fast just more power.

I'd look at www.nelsonperformance.com
I'm not positive but I think they're seeing from 35-50 extra hp with the tune on a 6.0, depending on how aggressive it is. Its a whole new pcm (computer) and he'll send you a tuned one and you pop it in then send your stock one back to him
