Ill see if I can get a video of it tonight.
I didnt think about the stamped arms slapping the valve spring retainers... that would make some sense considering how flat they are on the bottom.
I was going to try putting my 273 adjustable rockers back on tonight to see what it did again.
Also, I think I forgot to mention this is barely predominant at low rpm, but very much so above say 1500, and extremely loud at 2500+ under load.
Thank you all VERY Much for all the input and suggestions. I'll look into some tonight and post my analysis.
