That thing sounds awesome. I don't think that it will lope quite as much in the LQ9 though. Are the Aerochamber mufflers loud? I'm have a GMPP cat back on there right now, and it sounds decent, but I wish it was a tad louder. I am going to be putting on a set of the OBX LT's in the near future, so that should wake it up a decent amount.
I know the basics with cams, but not much more. How would something like this compare to the XR269?

the specs are very similar from what I can tell. Does the added lift make a big difference? The operating range is a lot smaller, but that could just be the difference between the way TF and Comp rate their products.

As for the operating range, that's just the way they rate their cams like you mentioned. Comp seems to be very generous with their operating ranges compared to other manufacturers, seems like they give themselves a few hundred extra rpm down low...just an observation I've made.

If it were me I'd go a little bigger. It looks like a good cam. I thought the same as you when I started looking for a cam. I went 212/218, I've had two since and I'm getting ready to do my third. Ask some of the guys on here, don't be a victim of to conservative of combo. It will cost you more in the long run. That is a really mild cam for a 6.0, I'm afraid your gonna want more later. if your gonna get a converter also, I would definatly not be scared of more cam even in the low end. There are lots of guy meeting emissions with 224 duration cams in 5.7 F bodies. Keep the cats and you'll be ok.

You gotta realize too....this guy has a big heavy denali. This isn't no small reg cab. Once you start putting in big cams and bigger stall the gas mileage just goes to ****. I'm getting about 10.5 myself, with a best avg of 13.8 babying the **** out of it. My opinon is stick with the cam listed in the OP, and go with a circle D 3000 stall. It will make for a good DD, while retaining stock manners and gas mileage. I dont get the vibe that he's going for a drag racer.

I didn't know you ran the 212/218. Zippy described it to me in a 6.0 as just like the stock cam, but "more power everywhere."

Bottom line is this, I want a well mannered truck that is going to have a little chop at idle, and give me more power. Like I said in the OP I am concerned with reliability, bottom end power, and gas mileage (within reason).
My main goal is to run a mid 13 with this cam, TB converter, CAI, LT's and a cat back. Am I dreaming?
Thanks for all the help so far guys!
