Looks like a cool kit with the tensioner. I made my own with pulleys from 440 source I used factory brackets for the alt and power steering. How ever I did build brackets for the small ac compressor and mounted it low. Mine doesn't use a tensioner but I've done this exact set up on two cars with bigblocks and haven't had any problems with just the idler. This one has a powermaster 150amp alt and the other is a billet unit from quality power.
