Well my engine started making a noise last night. It's a light clatter noise when you rev it up, and it also makes it some when the rpms come back down.

It sounds fine at idle.

Rod bearing? #7 piston? What do u think? I took the valve covers off and ran it and everything sounded fine on top.

I think im going to put some ported heads and a bigger cam in now.
