Hello, I have a 68 barracuda convertible with a original 318 4bbl with an upgraded cam, indy heads 3 spd auto. I installed the cam last summer and broke in fine. Towards the end of summer i noticed a ticking sound which i thought was an exhaust leak. I went for a little drive this afternoon and was getting on the throttle when i noticed a very fast tapping sound got it home and made this recording. I'm thinking a lifter but i'm not an expert. I would add a link but this system won't let me embed the youtube video. Maybe someone can tell me how i can or upload a video.
