lumpiest cam

I agree with the old Super Stock cam , most cams after a certain point sound similar. Big cams with compression will have a sharper sound however it is not what you were asking. I have a .474 in my garbage truck and it sounds like a .484 , .509 for the most part in my opinion. The post above suggests the .528 solid but I found it to be quite mild as far as idle , again just my observation. I used a superstock roller cam once that idled at 1100 rpm and shook the windows but never had a hydraulic sound like that ever.
