Welcome to CHR. We've got several guys on here (Dave Severson's one...) who can give you some advice on a cam, but the one thing you've said that's going to get you into trouble is,
I'm also wanting a nice lopey idle.
You want to select your cam for power and torque where you'll use it, and let the idle take care of itself. If you select a cam for lots of overlap, like Comp Cams Thumper or Mutha Thumper, you may actually have an anemic engine that performs worse than stock, but makes the kids at the local gathering place fall all over themselves with a "Poser" idle. You're going to have to start with some specific details of your engine build. Maybe one of the guys with the real know how will jump in here, even though you've stumbled with that lopey idle statement.

Again, welcome to the forum!!
