Input on a Serpintine setup

Have a march set up on my 340, love the look of the billet but when I had a charging problem last year I couldn't just go to the parts store and get another one just to check it out

That is the only down fall I seen so far

My small block set up from march with billet power steering pump was about 1,300. Had to change the clutch on the A/C compressor also another $100 and then make a adapter to use the billet nose on the clutch since the compressor wasn't made for the newer setup.
