Fan clutch? Doesn't sound like a rod knock or lifters to me.

check the fan and shroud.

also a long screw driver or extention pressed against you ear and various areas of the engine can help locate the noise.

I say fan/fan shroud.

For me, it’s hard to hear the true sound. But doesn’t sound like it’s an internal issue. Hope not anyways.

check that the fuel pump pin hasn't eaten its way out of the housing, the one on my 76 did and was making a ticking noise, the pump still worked as the fuel pump plate kept if from going anywhere. That was a 2 year old oreilys precision pump

Heres a vid for all you guys saying fan. Video cut off just as i found another issue possibly causing the noise. ****** no memory phone!

The push rod?

The push rod?

The pin that the arm pivots on inside the pump can wear out the housing and start moving around
