What cam should I use on 318?

This is a father-son project (I'm the father). The boy will be driving it around town this spring and summer, cruising and I hope to eventually get the wife in it for some longer trips. Looking for cool with a little performance uptick, nothing crazy. Want the classic hot rod rumble too but don't want it to be stalling out. But I'm not in for a stall converter. Don't know gear ratios but it's a small, stock rear-end, nothing special. Running 225/70R15 on the back.

Thanks for the help!

A little gas mileage would be nice too, but my real car is a Durango RT with a Hemi, so I'm used to 20-22 MPG highway.
