Sell the chevy 1 wire garbage to the next poor S.O.B. and throw a Ford 3g on it.

A large case Ford 3G unit is a good way to go if you are on a budget. It will give you probably another 30 amps or so at idle, assuming that you have the correct pulley ration. I have several used 3G alternators that are in great shape that I can sell pretty cheap if you want to go that route.

Or, if you want the really good stuff....

We actually manufacture our own billet alternators available in a wide variety of bolt patterns, including the delco alternators like the Power master you have. We used to be owned by powermaster, so I am very familiar with how those units perform at low RPM.

Our units use new 6 phase technology, and make 170+ amps with 150 amps at idle, they are bad to the bone... We specifically developed them because so many people need more juice at low RPMs, even with the smallest possible alternator pulley on it. The billet units will also tolerate a lot more RPM, and are also more resistant to dirt/water contamination.

Here's a comparo video showing one of our 150 amp units on the dyno:

We had a yellow star, and it expired. One of my guys has contacted camo twice with no reply. I'd happily renew if someone would get back to me...

Besides that, Poly Performance carries our Billet racing units, so we generally just refer sales on here to them anyway.
