Cam (combination) question - Comp Cams XE268H

I'm wondering if this cam would work OK with my other pieces:

64 Valiant, 904 trans (stock ratios), 3.55 rear end
360 block, flat top pistons at zero deck, 596 casting heads (just a little bowl cleanup, no porting)
Intake will probably be RPM Air Gap, and open to carb recommendations.

Assuming an appropriate torque converter and suspension, are mid 13's and 16 mpg (highway) possible with that combination?

If not, what are reasonable expectations? Thanks
