that's what i thought. thanks for your help. I guess I'm gonna open her up.

When its opened up make sure the cam is not a boat cam, they made a reverse rotation 318 for boats. Could have got in there. Just a thought. If it were me and I opened it up and found valve timing is spot on, I would swap the camshaft. :burnout:MT
