1998 360 Magnum cam help

I got a 360 magnum from a 1998 dodge ram with 97K miles on it. Im looking to do a mild build and bump up my power. I'm not looking for anything crazy, i wont be taking it to the drag strip although i might be getting into a bit of trouble around town :D I want to be able to use regular cheap pump fuel and i dont want to kill my mileage TOO badly...Dont want single digits..No point in having it if i cant afford to drive it. Can i get some Cam recommendations? I'm not looking to change my heads or bore it out ext. but i see mopar makes a 360 crate motor that makes 320 from the factory, so i should be able to at least make that?

I should also add that ill be ditching the fuel injection and running an eddelbrock 4bbl carb intake with shorty headers and electric ignition. I know some folks swear by long tube headers but the roads where i live are way too uneven and have too many unavoidable potholes, i cant have long headders dragging on the ground allover throwing sparks.
