I'm not good at posting links,but to give you a little of an idea,check out the article I wrote testing 8 cams in my 421.
I tested that Lunati and the 590 MP. There is a post on this board about the article. It was titled Keith Dunnuck's Fading Colors I believe.
Or go to Mopar Muscles website and look in the tech archives for Fading Colors,Hughes Engines has it on their website too since I tested one of their camshafts.
The 590 is 271- 272 @ .050 depending on which one you measure.
