2006 Denali 6.0 cam/heads/intake upgrade kit

[Hammartime]

I am a noob to this forum, I have an 06 Denali, I've owned it for 5 years, it has approximately 130k miles. It has a 5/3 drop, Flowmaster 44's, front & rear sway bars, and a cold air intake...Nothing special. It's time to do a little performance building on the motor. What's a good cam/heads/intake kit upgrade for it? I have thought about a supercharger, but I think I'd rather build the motor first, and see if that scratches my itch. I also plan to do some drive trainwork Iin the future and would like to hear what you guys have done to build your transmissions and Differentials with the AWD, or have anyof you converted to 2wd? Thanks in advance!

Do a 4l80 trans swap with a 3-3200k tight converter, before scratching that itch.

After that some 243/799 heads milled .30 with a 08-12 intake and a set of long tubes.
Cam choice will be yours.

 

[Hammartime]

Probably not a bad idea, but that alone definitely won't cure my itch.

 

[ezdaar]

408 stroker with L92 heads and intake or a Holley midram, that should cure your itch.

Just looking for a cam/heads/intake combo that you guys have experience with, not trying to go all out....Yet.

Then what you want is in my first post.
With right cam your looking at a easy 100hp upgrade.
If you want more. Install a 150 shot wet no2 kit.

But given the cost of those upgrades and the np2 kit. You could easily just install a on3 turbo kit for aprox same cost and be instantly over 500hp

Love the way you think EZ!! Great ideas for sure!

 

[Hammartime]

Excellent I will look into that, I didn't see the edit of your first post. Thanks Doug.

That turbo just might be what I'm looking for....Then when I blow up my motor and tranny I can go with the 408 stroker

The 317 head ports match those of the 243/799. I don't see a reason to swap, you would benefit from getting yours milled a little and a nice port job.

For a cam I'd recommend the stage 2 drop in cam from Cam Motion. A buddy used one on his stock 5.3 and picked up 42whp on the worlds stingiest dyno. It's made to be a usable truck cam without any compromises.

Unless you swap to a 4l80, you can get a stock converter from a 4.2L TB. On my 5.3 it stalls 2600rpm. With your 6.0 it would be even higher and you can pick them up for about $120 if you talk sweet to a parts manager. #12491321


As far as the intake goes, the newer style is better, if you've got the money I'd pony up for a FAST or Holley intake.

If i upgrade to that tranny, will it work with my awd? Or do I have to change it to 2wd?
