Hey Bob, I've got the early 1160/3208 Industrial version, non turbo 225hp has a rear sump pan and I got it right back at the firewall and everything clears...barely. Oh, you may need to just 'touch' the frame to make the starter clear depending on where you mount it. With just 225hp, there's a BIG difference in the truck...not gonna win any races, but it's got more kick. I'm happy with it. Have fun with your air compressor. Heh,heh. :yeah:
