Help with Cam choice

Looking to add some bolt on power to a 318 with good compression and doesn't burn drop of oil. It has an edelbrock 600cfm with an edelbrock LD4B intake and 1.5 inch headers. I was planning on adding a set of edelbrock aluminum heads 63cc chamber and was looking for some cam suggestions. No racing just cruising, has a 904 trans with a 2500 stall and a shift kit, 8 3/4 rear with 3.23 gears. It's in a 1969 satellite convertible, would like a nice choppy idle. Thanks
