if its am aftermarket copy of a Z06 cam than what was said about ramps is correct - and not all motors sound the same a slight difference in the blocks casting will make a big difference in sound some have a hollow knock forever some have like you describe - you did not say how many miles you have driven it and how hard it has been driven so far ??? -- also if the type of oil you may have been using was not used and weight you could be hearing that as well --jz
