Pick my cam?

Ok, relevent specs are as follows:

1964 Dart 170 2dr sedan 2800-3000lbs
Manual brakes
4spd overdrive
8.25" rear with 3.55fd SG
26" tall rear tires

360 .060 over (371ci)
H116CP SpeedPro pistons Hypereutectic
Measured cr of 9.8:1
Other wise stock bottom rotating assembly
Stock 587 heads with 1.88/1.60 valves
Stock HP 340 exhaust manifolds
Eddy LD340 intake manifold
carb-undecided (most likely 750cfm)

And all the above info is not speculation or wishing. It's actually what I've got on the stand to put in the car. So suggesting different pistons or aluminum heads won't change anything.

The intent for the car is a fun daily driver. I'm not expecting great mileage or an 11sec street car. However, I'd like it to be able to get mid teens mpg and maybe dip into the 12s.

So what do you guys suggest?
