I have the same PS setup on my 'Cuda. They made the billet reservoir too small and the PS Fluid will boil out. I added a PS cooler and it helps, but when I beat on it it still boils out. I carry a qt of PS fluid in my car now. It's a shame cause I love the looks.

Thought I had a picture somewhere. Here's my PS cooler setup. I run a 100 amp alt 3 wire and a constant voltage regulator (the blue one) with 2 batteries. I bypassed the amp meter for a voltmeter and used a heavier wire. Never had a problem with charging.
