Glad you got that fixed, and thanks for the info. I have a Vintage Air setup on my 440, with the same issue with only running 1 belt. The kit came with a plethora or spacers that had to be played with to even get the pulleys to line up. My engine builder said it took him almost 8 hours to get it all right. The inside groove of the compressor-to-alternator cannot be used because the alt & PS bolt heads are right in the middle of where the belt would go. If I ever get bored I may play with it to see what I can do. The NAPA belt my builder used squealed terribly so I changed to a Dayco Top Cog style belt which resolved that. I would certainly like to run 2 belts though. Less stress on the bearings and better grip on all.
