what cam for 340 bored 0.30 over?

In my 340 .030 I am running a .509 purple cam with Hyd flat tappets, 3500 stall, 750 eddy, RPM air gap intake, 727 tranny with shift kit, MSD and I love the way my girl runs... I did no major changes when adding the cam, just a complete rebuild...12 yrs later still running strong.....
