So, settled on some things.
a 12mm pump for drivability. Adjustable timing gear and billet cover. New head casting. oringed and ARP2000 studs. 24v STORM block (56 casting). ARP main studs. cam is 188/220 Colt. turbos are 64mm ballbearing watercooled GT3788R over 80mm GT47. SBC3650 ceramic dual disk in front of an '05 dodge G56.

No 9 speed!!??...what a disappointment 
Even my daughter was telling me yesterday how excited she is to see it!
She wants a Cummins with a standard.

Opted for the 6 instead of the 9. The extra cost and headache of install just didn't bring any benefit.
But don't worry. It's staying on hand for another project for sure.

I thought you bought some monster 13mm pump to use? Or was that just the original plan?
Even with a 12mm pump, with those turbos it'll be beast for sure.

You could give me the deuce! I could make something out of that.

That was the original layout. But that pump is going onto a race truck. And a wide open 12mm will give me more than enough fuel for my business with it.
Got it. A 13mm pump would be pretty crazy to try and run on the street. Yea witht that 12mm pump and those turbos you should make some serious hp!

Is that black billet block on the back of the engine block for coolant?
And does it have a thermostat?

Yes and yes. You remove the rear freeze plug from the head and bolt that on. It's a lower temperature than the actual thermostat. So there's always coolant flowing out past the #5 & #6 cylinders. The line returns to a similar fixture that bolts between the upper rad hose and stat housing.
I thought so, that thing looked a little too fancy for just something to tap coolant though.

Ya it's an engineered coolant bypass. To save the 6 and 5 hole from overheating and sticking a piston. And also relieving excessive coolant pressure from high rpm use.
Dumb question, what is the RPM range for a "high RPM diesel".
I'm used to seeing 7000 to 8000 rpms for gas motors and there are some that can rev higher than that.

When you see 5000+ rpm in a cummins you better be built and balanced. But realistically you would only be doing that racing or sled pulling. Day to day operations and 4000rpm will do anything you need it to.
The higher rpm in racing actually helps the higher horsepower engines stay together.
