A question on weak drawing hands.

[frappeboy]

Lets say you start off with a hand like 567 in a multi-way pot. The person directly to your right holds a large pair (Lets say kings). On 4th street you catch an 8 and everyone behind you catches blanks. If the king bets, is it better to raise to knock out 3 flushes/larger 3 straights who would take off another card if you just called, or should you just call and let them in?
