The truck has d.o.d will that effect my swap and what motor mounts do I need thanks

no engine harness, no computer, no pedal, no tac module harness, no tac module, no accessories, no a/c lines, no radiator hoses, engine mounts, no frame mounts. i dont think its complete until you have these

I found another one a 6.0 that has everything out of an 08 2500 Will the wiring harness and everything match up Will be using both motor and trans

No. If your truck is 07 GMT800, you need a harness from an 05-07 GMT800. Let me know how it goes, no one has ever done this swap before as there is obviously no available information.

I'm 16 and bought a truck Now that I got my taxes back and made more money I can do my swap Havnt bought anything yet, trying to find a motor but keep coming across motors from 01 or 08 can find 04-06

You can make either motor work. It's the harness that needs to be specific.
