John, Don't know about a 496, but something that might be interesting to you is WESCO is upgrading some Merc 500EFI's (502cid) to some 540cid EFI engines for a guy out of Florida. He's still using the stock Merc EFI intake manifolds, but going to a larger throttle body, new Pro-Topline 320cc heads with just some light clean-up around the valves, aftermarket hydraulic roller cams, 9.2 comp ratio, and computer remap upgrade from Tyler Crocket.
He doesn't expect them to make much HP because the Merc 500EFI intake manifold is somewhat restrictive on air flow to some degree, but torque and throttle response should be a real KICK though. He should have the first one on the dyno in about a few days.
