I see the numbers stamped in the carb pad. Same numbers cast into the intake?
MoPar can be strange in there intakes since they look the same but get rated at different RPM's. I'd call that one 2-1/2 or 3 to 6-1/2 or 7 Grand rpm's. No doubt it is a new style intake with the Magnum styled water outlets and T-stat housing.
If you have a spare intake gasket layin around, match it up. See if the intake bolts line up. If the inners do not, and the ports are rectangle, chances are it is a W-5. If the ports are raised up, the game has changed yet again on the W-? game.
