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
I've run mid 12's with less in a 3300 street car. 360 with low 9.6 -1 comp, crower 31242 222/234 112, lowly performer manifold with 600 edelbrock, ported 302's, 3.73 gears and 2 dud cylinders and no fuel pressure.
