Since it's a 4x4, that means TWO sets of gear changes

We pull up muddy and snowy climbs and I expect to be needing 4 wheel drive, under load.

I'm looking at some motor mods at this point only because the motor is already partially disassembled. The heads are already heading into the machine shop anyway so I though I'd use a better hear.

The cam was optional as we're not that far disassembled, but for an extra hour or two of labor we could have an RV cam in there as well.
