I am looking at options for onboard air. How do you mount/power an a/c compressor (york?) on a Chevy 350 with the serpentine belt system without removing the stock a/c. I want to keep the a/c. Has anyone mounted one? What do you drive it off of? Pictures would be great. I have a 6 1/2 gallon tank with a presure switch and plenty of room to mount it, so I am also considering a compressor. Anyone use one? How fast can you air up 35's? I have looked at tanks, but decided that I want to have unlimited air.
