The K31 is definitely the best option for a stock 470
I'd get the '98 for sure. The other two, based on the year, are ddec ii. They would be OK in a mostly stock application but I wouldn't even bother...
GU, GK, PK, TK, and HK all used 15:1 compression. 16.5:1 started with BK and MK. It was the low-nox programing that caused most of the smoking...
With stock pulsewidth (about 30 degrees) and 7473 injectors, my original compound setup would do over 60# boost but the gauge only went to 60 so I...
The 309 cam is pretty good for highway driving. I really like the 7014 injectors. You can get great fuel economy with them, make a ton of power...
I took my original turbo off around 1.2 million miles and it was due to the wastewater actuator failing. I gave it away and it's still working...
Clean all your electrical connections. Batteries, starter, all your grounds, etc. Don't be afraid to add a few extra grounds. Your issue with the...
If by better you mean higher flowing, the 7650s are the better option
Before may '98 nothing was drilled from the factory, not even the pk. Once they started drilling, they drilled everything.
I thought so. 6978s are the smallest n2 injectors they make. You'll lose a lot of power going to those
Don't plug your wastegate. That rise you'll see on the boost gauge is only because your drive pressure is going crazy. You'll over speed the turbo...
Are you 100% sure about that part number?
This is basically it but don't use the ddec 5 cam. Go to a machine shop and have them make you an adapter to run a ddec 4 cam. The fives use...
There are a few wide block 12.7s out there that are the same as the 14L but most won't allow the crank to turn once the rods are installed. To...
It's just a few settings in the ecm that need to be changed. The dealer should be able to do it and if they can't, go somewhere else form now on...
It's better to have the proper parameters for the engine like you have now then have them go in and change what needs to be changed on the truck...
Fleet air filters. They're a foam/oil filter. As long as they're oiled properly (you'd be surprised how many people think they're doing it right...

If you put 5915 injectors in a DDEC 2 you'll instantly regret it. DDEC 2s use higher flowing injectors with less pulsewidth than later DDECs....
550hp is a long way from the max for a 12.7
