I upgraded my big 3 (actually 6) about a year ago and finally got around to posting a couple pictures. Very easy to do. Its worked out well for me, no trouble over the past year.
I used 1/0 cable for the following:
1. + Battery to alternator
2. + Battery to starter
3. + Battery to firewall block
4. – Battery to engine ground
5. – Battery to frame ground
And I used the 4 awg cable salvaged from the original battery cable to ground the body to the frame.
Here’s what I used:

I bought the fuse for the alternator connection but never installed it, instead I followed the most direct route from the alternator positive to the battery positive across the top of the fan shroud. I threaded the positive 1/0 cable from the battery to the starter in a piece of garden hose to give it more insulation, concerned with the engine heat on the cable, maybe overkill though.
I cut the 1/0 cable with a hacksaw, trimmed the rubber sheathing with a razor blade, hammer-crimped with a 3-lb hammer, soldered it for good measure, then used heat shrink.
Anyway, here’s some pictures.
