I will post a video , but the only other info i have is the tapping is coming from both sides of the engine while driving or at idle . The 402 build has about 3k on it , the only thing that comes to mind is the Harland sharp rocker arms coming loose ? If that's possible

Some things can only be determined in person...waste of forum members time and your time also. When an engine assembly is screwed up you or someone will have to take it apart until you determine the problem...hell of a learning curve though. Good luck.

If it's coming from the side of the block it could be a spun rod bearing. I have the Harland Sharpes on my car and it sounded more like a sewing machine then a knock. Then I spun a rod bearing and could def tell over the sound of the Harland Sharps..
