Need new engine

[Chris Ramsey]

After 280,000 miles my motor took a dump.
I let my son use it to take to his last day of school and at some point it lost all oil pressure with out him ever knowing or hearing any of the knocking and ticking.
Him having the stereo blasting to his crappy boom boom crap probably the reason why.
Any how. I love my h2 and could never replace it with anything comparable.
Its broke can't trade it in any way.
Any opinions on new 6.0 for it ?
New factory 6.0 w/ 6yr 100k war. = 7k installed
Re man w/3yr 30k war. 5.5k installed
used junk yard w/ 66k on it, 2k plus the install.
I'm leaning toward chevy doing the new motor due to the warranty since I could never replace this and will more than likely keep it forever.
Do I need my head examined for spending 7k on a 04 H2 to get new w/ 100k 6yr warranty ????
