Should 3C imply shortness in clubs or just a good invitational raise

During club play this hand came up. It should be simple but I can't think of the right bid [hv=pc=n&s=sq984hq63da9732c5&n=sakjt7ht85dkj5cj9&d=e&v=e&b=6&a=ppp1s2c]266|200[/hv] I feel possible bids are 2s,3s and 3c partner also suggest X can show drury or 2d, 4s was also suggested based on it being a 7 loser hand I'm not fond of that. So suggestions on what to bid here and the difference between 3c and 3s would be appreciated. Scoring is MP
