Usually hydraulic or mechanical refers to the type of lifter. They are hydraulic from the factory.

The maximum theoretical air a normally aspirated (no supercharger, turnocharger, or nitrous) 454 can pump at 5000 rpm is 650 cfm.  In practice it will be less than that.  So I think it is probably optimally carbureted at the moment.
