After a good cold one, I had a choice to run belts for my accessories, since my engine compartment is no where near stock, I went with the Detroit Speed serpentine system, its clean adds only 6.5 inches to the front of the small block and is wide as the footprint of the engine block. It was simple to install and work with my intentions. The people are great to deal with also. I found a picture that will show the complete layout. It added air and powering all in one operation.
I did the same thing with a March system. Considering that I plan to use this truck as a daily driver, I probably should have looked at the less shinny versions. I have a lot of chrome and billet aluminum to keep clean now.
