Why not a modern version of a big block? 502 cubic inches of goodness, already in the crate engine offerings. Add nice fuel injection and an 8 or 10 speed Allison trans, 4.56:1 diff gears, yeah, why not?

Sorry if this was asked before, what block will the 6.6L gas motor be based on?  I've been focusing on my Duramax since I got it on Labor Day.  If it's good enough, I might replace my 2003 2500 HD 6.0L with one for hunting and boondocking.  Basic crew cab 4x4 I can sleep out in.  One I don't mind getting desert pinstriping on (white is good color for that, hard to see it).  ? 

 

I'd  love to hang performance equipment on it like intake, headers and a good tuner.   Thanks

COWPIE IS WISE, I ALSO BELIEVE IN THE USE OF CATCH CANS. YOU SOUND LIKE AN OLD DRAG RACER WHICH IS MY ONLY LIFETIME HOBBY.  THERE ARE SOME REALLY NICE CATCH CANS ON EBAY FOR UNDER $20.00.
