I rebuilt my 289 7 years ago and put a new cam and oil pump in it (amongst all the other parts)...this summer the cam failed and it was suggested that the high output pump was the issue. ..regardless I am faced with what do I need to change now? Someone said metal shavings were possible so change the oil pump....I imagine that my filter caught any shaving s and a new pump is called for. Car soundsteering good less the bad camm...any suggestions?
