You are taking a chance if you don't. Tear it down and clean it out right. Quick refresh if possible...

You can get a "refresh" kit in A or B with new main and rod bearings, rings, and a complete gasket kit for $200.

there's a local used 318 with A/C and 727 out of a 73 fury that i was looking at buying for 450. but for 200 bucks i might as well pull mine and throw that kit in. more work, but i think it would be worth it.
