The sump on the C1C faces backwards. You'll need a forward- or downward-facing angle-valve sump and intake tubes, like on the IO-360-A1A. The prop governor is also front-mounted, so if you're going CS, you'll need to make arrangements for that as well.
I'm currently dealing with this as I have the O-360-F1A6, which is similar, but parallel-valve and non-injected.
