13.25 volts at idle with no load? that's low. should be in the 13.8-14.5 range, depending on temperature. the 13.5 number is also low for that rpm, with no to light load on the alternator. an internally regulated(10si/12si) is the preferred alternator with hei. it has a much more stable voltage which the hei likes.
i'm only addressing the electrical end with this post.
