I bought a 47 just recently and didn't sound bad and had no signs of bearing rap.
When I got to drive it at high speed you could hear the bearing. Started to rap about 1500 rpms. When you wind it up in first ,rap to 2nd rap and let off in 3nd 50pmh it raps. I luck the car seems much heaver then my 39 sedan. I just started to replace the engine with a 53 8rt truck engine and hope this engine works better.
