Another Cam selection thread

Here is what I have:

340, .030 over
KB 243 Pistons
X heads, basically stock. They are at the shop now being cleaned and checked to see what all they need, but I'm not planning on porting and polishing.
Dougs headers
Edelbrock air gap manifold
Undecided on carb
Undecided on ignition system
Dana 60 rear with 3.55 gears and big tires
4 speed

It will just be a street cruiser/ burnout machine.

So, what cam would be a good fit for this combo?
