Which ever one you like the looks of better, or if you don't want to put a Ford part in your Chevy. I'd ask GearFX which case they feel is machined better or has better tolerance.

I ordered mine from GearFX and asked this very same question. They explained it to me in depth and in understandable terms. This does you no good, but sorry I don't remember anything as it was about 4 months ago. As stated, give them a call. Very knowledgeable guys. DSE owns it so you know it's good. I did end up going with the "N" series. Ask for Fuzzy Horton....he knew his stuff.
