This is weird. Had my car running (1970 396) to check on a trans issue. All of a sudden it started to knock/clack and sounded like it was coming from the valve train. Turned it off, let it sit for a bit then started it back up. Now its running fine with NO noise. Ideas?

Probably a piece of carbon broke loose and landed in a lifter

Wasn’t this thing mysteriously smoking last week?

Shouldn't you be consulting with Q on this?

But, to your issue, have you checked the lash on the rocker arms to make sure the valves are adjusted correctly?

Double awt 7 are you running hydraulic or solid lifters?
Is there a chance you have oil pressure issues at idle allowing a lifter to collapse?
