590 Mp cam

Thanks guys. I have a 509 purple shaft in it now. I busted the side out of a lifter (hydraulic) and tearing the motor down this winter. Figured I'd change cam too. I want something street able with a night choppy idle. My dad uses comp 520/230 in his big block chevies and love them.
Motor is a 30 over 440, MP stage 6 al heads, max wedge cross ram intake. Six pack rods with flat tops. Crane roller rockers 1.5. I even pondered solid lifters but want it to be more maintenance free. If that's such a thing lol
