Hy gang. 

My friend Nahin owns a '67 Galaxie with a 292 (Brazilian car). He lives about 400 kms from me, and is having some trouble with his car.
He says the engine runs fine when cold, but has a strange noise he thinks come from the passenger side of the engine. After it gets hot, after some highway use, the engine gets rough, would die at idle, and will require burning the clutch to get to move like if it had a dirty carburetor, what is not the case. We know that, because he tested s second carburetor, and had the same result.
Today he sent me a video, and I think his engine is knocking, and bad. Maybe his oil pressure goes really down when hot, and that has already damaged the engine, that gets rough because it's getting really hot and that is causing some sort of vapor lock on the fuel pump, or maybe boiling the fuel inside the line itself.
I'll post a video he sent me, that shows the noise pretty well. 
I would like a second third and fourth opinions before telling him his engine is kaput.
What do you guys think??
