When I started learning about flatheads many years ago, the "B" series fan belts were what many recommended for 5/8" wide applications, and a 55" X 5/8" B 52 was perfect for mine.

The belt lasted 20K miles for 10 years but is totally shot with damage I've never seen. Small pulley diameters may be the problem. I have learned these B series belts are really for industrial applications, so I need recommendations on a better automotive belt, and wonder what you guys use.
I did find a NAPA 25 22553 belt that is one inch longer, but the 52" id/55" length would be better if possible. Thanks.
