I'm probably going to end up using the rotating assembly from the motor Ed's brother brought me, it had a bit of water in a couple of cylinders and some rust but hopefully no pitting.
After I get the block all cleaned up, I need to decide which set of heads I'm going to use. I will use the lower performance ones for now, and rebuild the better ones to put on later. I have been doing some browsing over on the diesel page and have gotten learn't on which heads are better for what. I'll get some pics and post em up later.
Well today me and Ryan finished disassembling the "new" motor and we are deffinately going to use it. One cylinder has a bit of surface rust on it but the rest of the motor is actually in excelent shape. We cleaned the **** out of it today and will do the honing and begin reassembly tomorow.
The "old" motor turned out to have 3 cracked pistons, here's some pics of the shatyness.
A few more. You know its actually prety impressive that this thing ran at all with how F'd up it was inside.
Ditto man. I have a new found respect for 6.2's, I'm really surprised it held up to all that.
so you are assuming hydro-locking it didnt crack any of the pistons?
I was never hydrolocked. When it died at Alto there was no water in the cylinders, I took all the glowplugs out and cranked it over to check. I think the water that caused the rust in the cylinders came from when I was hosing the mud off the truck. I wasnt really concerned about the motor at that point so I was just spraying the **** out of everything in the engine compartment.

There are two kinds of heads - 6.2 and 6.5. Within that there are some variations of mounting points for accessories, but not much more. The primary difference is the angle of the injectors, and the prechambers that came in the head. Either head can run any injector, and accepts all prechambers.
I recommend 6.5TD injectors (short body) on your regular 6.2L heads (just bend the injector lines to fit) with the small economy prechamber (probably what is already in the head). That will give you a good, clean burn and will work very well with a turbo.
From what I read on the diesel page it sounded like for power I wanted the larger prechambers from later 6.5s. They sacrificed the better fuel economy of the smaller prechambers in order to produce more power but this is pigpen so mileage aint no concern. As of right now it looks like I'm going to have to get the block bored out .020 because of cylinder wear. I was hoping to avoid this due to the extra expense, are there any cheaper options?

Are you refering to a bottle brush? If so, how would that help worn cylinder walls?
