Upgrading the 2004 work horse
As it sits, my 2004 3/4 ton engine locked up New Years morning. So, instead of replacing the 6 liter and keep on going, I have to give in to the usual. More power.
Now, the newer trucks are nicer and have more power, but at a cost I refuse to spend. The truck breaking is kind of a blessing since I want more power for pulling and generally beating in the truck when I like.
So, I'll be trying to find a replacement 6 liter. Here is what I have in mind and the only thing I think may be a issue is my cam selection. I'm sure there are better ideas of what to use and I'm open to input.
99-2004 6 liter is what I need.
I have a set of 853s off a LS1, one is ported and I need to finish the other. So these heads ported and maybe milled a bit should help power and torque between the smaller chamber and the ability to flow 280 cfm.
Cam, I am so far thinking a LS6 cam would work great with some valve springs.
A set of full length headers and Y pipe.
And of course a tune.
This should no doubt break 400 FWHP, and if I got lucky and found the info needed, I would like to throw a 2007-2013 intake on the truck. I'm sure a larger TB would be the end of the parts list there.
So. Any ideas for my resurrection of this work horse of mine are welcome. I have also thought about having the stock converter re stalled to help it get into power. We will see how that goes.

I like the plan other than the LS6 cam. I say step it up to a 212/218 110+4 or something similar. your plan is basically exactly what I wanted to do with my HD before it was stolen. intake/headers, swap the dual exhaust for a single setup, mild cam, bump compression, tune and let her eat. I basically wanted all torque below 4,500 RPM. my truck had no reason to ever go past 5k, even with a spirited freeway pass.

Yea, the LS6 cam is just along the lines of the cost effective solution beyond the LQ4 cam. And I know it will make power from nill to 6, which sounds great to me.

Right now it has a bullet dumped at the axle and that will still be there but no cats. So it will go from loud to way too loud. That may cause me to go from the 6" to the 12" to tone it back.
Money money money. I would rather be building a 402 stroker and the works here. But used is my friend. If I for whatever reason find a converter used that will work, awesome. A new can? Cannot do it. I am fixing this and then swapping engines in my mustang. Gotta stretch these dollars. Lol

Gotya..ive got a 06 crewcab vortecmax with a lq9 6.0..im on the fence on swapping my true duals to a 3" catless y pipe to a single 3" pipe into a si/do muffler..ive been told a single 3" would be better for what im wanting and then again ive been told to keep my duals..there is a thread in dyno section that backs up the single 3" setup though...

Sounds right to me. The low end likes the Y pipe in my experience. Top end power is different since it is trying to ditch spent fuel quick, fast and in a hurry.
I cannot keep the stock cam since I want more power in the rpm. Just moving things up a little and modding the stock converter to help it get there.
