Cam identification help

I have an unknown cam that I pulled from a heavily modified 440. No part numbers that I have found. It has purple paint on it, measuring the base circle is 1.150 and heel to nose is 1.530. So if I’m doing the math correctly the lift is 1.530-1.150=.38*1.5=.57

I can not find any cams that are .570 lift. Does anyone have any information on a cam like this?
