So I bought a 2006 2500HD 6.0 work truck with 8' bed already lifted, really taken care of, new tires, new inspection, I mean all around a very very solid rust free tuck for 9000.

I have a fully built 95 k1500 5 speed manual, so I decided to build up my work truck since I got a really good deal on the truck, plus I know the 6.0 has big potential. The only downside to the 2500HD is she is a automatic, couldn't find any other truck for that cheap and in such good condition and with what it had done to it with a manual.

Here's the build: (COST's: 9000 for truck, 5000 in parts, labor 3500) 17,500 total expenses, including tuning dyno, and all the hard grunt labor of doing **** I don't have time to do.

Upgraded GM Valves
.660 PRC/PAC dual spring kit with titanium retainers all milled to 229/236 Cam

I should have the truck tuned and dynoed by Tuesday maybe Wednesday if all goes to plan this month, so I was looking for critique if this should be a good set up for the truck, a little to late but before I get the truck back after the week and half its been in my shop. I wanted to hear some feedback on maybe potential horsepower numbers, or if anyone has a similar set up would recommend for me for the future. Hope you guys like the project keep you guys posted with progress.


I'll post pictures of the truck if anyone wants to see it and hopefully a video of truck running and dyno sheets! Hoping for 500 N/A is that realistic with this set up on the truck?

 

Buy none of the parts, put an lsa supercharger on it, and make more power for less money with no extra maintenance required.

 

Yes, ^^^This

 

Reading the OP I was going to state that the ported rectangle port heads would result in a severe loss of low end torque and a problem for a heavy vehicle(so stay cathedral or at least don't port the heads too much)..But LSA blower is a great idea. Doing one myself for the same reason.

 

Given that this is already underway, by the sounds of it, there is no point in trying to change anything on the list. I would have stayed with cathedral port heads on a heavy *** truck, personally, but what is done is done.

All that being said, now that you have rectangle port heads, the LSA blower will bolt right up, no problems, so you are halfway there. And ported heads with a blower will be lots of fun, you can say it was part of the plan all along.

But... without a blower, my predictions are that thing is a dog down low. Big intake runners, long tube headers, and a stall over 3k... none of that is heavy duty truck stuff, in my opinion.
