Change that from Dirtymax to Cummandfixit and then you jumped into my shoes.
Side note, I'm trying to get ahold of a farcebook guy on an 07 Dirtymax without the Dirtymax. I was the Allison A1000 and transfer case.
I've got a 12-valve that I traded my buddy some parts for, I just need to pay the $400 I owe him and I get a block, a pair of heads and a set of manifolds.
I long thought about a Cummins swap in the green truck, but I love my dad's 03 LB7 so much and I know that would be a little bit more of a "comfier" mill for a truck that's going to pull the family camper when that time comes.
However I do believe a 67-72 K20 with a Cummins would make an absolute honey of a weekend warrior rig....or maybe 12V swap my 96...
