I have one of Scotts cams in my 390 in my 67 Highboy. Its been in there probably 15yrs. When I talked to Scott he recommended the break in machine since it was a pretty aggressive lobe and said it could beat down a lifter. So, I had him put it on the machine. It was $60 back then. After a few weeks of running the engine I started having lifter noise upon start up. I believe its only one, maybe 2 lifters. They quiet down after a few seconds so I've never replaced them. Once in a while one will really tick upon start and it will hammer for a while. I have talked to Scott about it and he said it could have been the aggressive ramps on the cam but I just never have replaced them.
