454 Engine noise.... Any ideas?
I had a ticking noise coming from my engine and thought it was the water pump whining and going bad. I replaced the water pump but the noise hasnt gone away. My oil pressure seems to be changing. It drops to 20-30 at idle and goes back up to 60 under load. The noise also goes away under load. Did I lose a ring? I'm going to try and get one more poker run out of her. Is ther any chance this could be valve adjustment issues? Any steps for process of elimination would be nice. I bag also heard that its cheaper to just replace these blocks for a $3000 long block than rebuild the 454's. Any truth there?

Mechanic said they didnt notice anything a few weeks ago when they had it. He thinks it could be the exhaust flappers inside the y pipe rattling. On the oil pressure; thinks the guage could be going bad possibly because they saw no issues with oil pressure
