Just to add my 2 cents:
I picked up the newer style alternator (lookup 2016 2500HD silverado 6.0) and
you'll easily find the new style 220 amp alternator.
It basically bolts right in...You have to tighten the 2 bolt insert washers a bit more..
I measured that distance on the OE alternator and the newer denso style.. It was about
2 MM Difference , so no big deal..
My alternator bracket is offset due to my edelbrock supercharger, so the oe alt had to
be "clocked" 1 notch.
The new style alt will have to be clocked 1 notch OR an extension used on the 2 pin
wire harness that goes into the side. The main power was no issue at all.
I returned the alt to my parts store as I have an account, so no big deal.
I'm deciding on the options: 1: Change over to new style 220 amp and lengthen the 2 wire hookup
2: Do the Mechman 250 amp alt - I talked to them, I need the 250 amp model due to the fact
that the 240 amp model is "unclockable"
3: Just do a bit smaller pulley on my OE 160 amp ----- this is what I'm going to do first
to try it out. I'm going with a 57 mm pulley that I found on ebay (thanks to this post).
The stock is 2.46" and 57mm is 2.24".. So I won't really screw up my belt sizing and
the ratio rpms
