So a little update on this. After all of the work and 4 gauge cable add and crap wires delete, I've determined I like this alternator. If I were to do it over again, I'd probably just go with the Jaguar 120A alt that YOguyDA posted about.
Was all this extra work really worth 20 extra Amps over a bolt on? I don't know. I've taken it on two light trips to the High Lakes. Plus I don't have my winch mounted yet, so I'm not putting any heavy load on it. But it keeps my Mexican Optima Red Top alive, so that makes me happy. I did end up getting a one size shorter belt from NAPA, and cant remember the number off the top of my head. It was a tight slip on the required turning the crank by hand to roll it on, but I still have a bit of adjustment left now compared to being on the end of the adjuster bracket with the original size belt.
While finishing this project 2 months ago, I acquired a 97 4Runner 3.4L to swap in here in a couple weeks. I held my old 60A Alt up to the 3.4 and found that my 140A Alt should slip right in with little to no modification. I'll just throw the original serpentine pulley back on the Alt and roll with it.
If anyone is intersted in how that will go, I'll post the details in the build thread I'll be doing here soon for my full revamp of the truck.
Going 3.4, R151 Dual cases, 4.7s rear, chromo outputs front and rear, and 60/14 combo swap. You know, the standard.
