So I guess I'll be starting a build thread to document when and what happens to my truck and engine as things progress. Wasn't planning on starting building now already, had wanted to wait till I take my truck off the road, but I holed a piston last week, so... The truck currently has 170K miles, I run 80-90K a year. My plan is to upgrade the internals, and to get the engine running cooler while towing. I don't want to sacrifice reliability, so I won't be doing everything I had originally planned to do. I'll have to wait till I retire the truck to do an all-out engine build... Feel free to chime in with advice/suggestions...

Here is what I currently have done to the truck:

-S&B intake
-5" downpipe back no-muffler exhaust
-Kory's tunes
-Airdog II 4G
-CTS2 moniter

Plans are to add:
-Fingers oval bowl pistons
-Thought about doing Carrillo rods, but since I won't be building a high horspower application, I thought I'd wait to do that till the truck retires, and I do a full build. I can use the money on something else. Think that'll be alright?
-CP3 over CP4 : Maybe, thoughts? Wait for this till later?
-ARP head studs
-SDP S475 over stock turbo : Will I have to use the SDP intake and coolant tank with their twin kit?
-Will be putting together an oil cooler system, not sure where I'll mount it yet, would like to mount it in the front, but there's not much place there, so might have to mount it underneath somewhere with fan...
-Maybe upgraded intercooler??

So what are your thoughts? I'm still in the planning stage, and need to make some calls tomorrow morning to make sure I'm on the right track. I'll be doing the build myself. I hope to start teardown on Tuesday or Wednesday...

As she sits right now...

That is a 2015 twin kit Scott did. I believe I seen this one in person when he was putting it together. Visit his site or give him a call to see what options you have as far as coolant tank, hotside pipe, up pipes and manifolds, and the obvious color choice.

Rather than a cp3 over the cp4 I would start with a 10mm CP3 in the valley. Should be enough fuel for 700hp and the cp3 in the valley is much more reliable.

I do know CP3s are more reliable, but will a modded CP3 be reliable enough for heavy hauling?

I don't know what kinda power you are looking for but I'd say the best bet is a stock cp3 in the valley and if that's not enough fuel go with a duel fuel with a stock over stock since you are going for reliability ! Definitely don't put a cp4 back in there haha good luck and I'm subbing for sure .......

How much power would a stock CP3/stock CP3 + Airdog support? My future build will be for big power, and upgraded sticks, so I'm kinda thinking just leave the CP4 in there for now, and if it takes everything out, then that would be the lightening from heaven saying dual fuelers/sticks...

Definitely one way to look at it

Dual stock cp3 will make 1000 with the right injectors and air

Me personally, if your building the motor, I wouldnt put a cp4 back on it and risk it grenading and taking the rest of the fuel system. It's not cheap and won't be easy on the wallet after an engine build. A stock cp3 can support over 600. I would put a cp3 or sportsman pump in the valley and if you need more fuel then throw a stock one on with it.

From what I understand even stock cp3 will produce slightly more power than a CP4 because it is a higher flowing pump. As mentioned even on stock sticks you should be able to make a reliable 600hp.
