boxed frame and solid mounts isnt any more uncomfortable than a unibody... wich practically is what it is...

WE strongly suggest using solid mounts on our subframes, they just keep everything in the correct location. but there is very little road noise over rubber. the handling and response will improve.
There will definitely be more harmonic transfer changing to solid body mounts. Especially from rubber. New cars aren't a good comparison, they are very well engineered and offer great isolation from harmonics. If it's a cruiser or a car show queen, rubber is the way to go. If you plan on letting it all hang out on a regular basis, Things need firmed up. You can fight the harmonics by using rubber motor mounts, trans, steering coupler, etc.
Thanks for the replies, kinda echoes what I was thinking. This is a driver but all the suspension and drivetrain are rubber insulated so I'm hoping the transfer will be minimal.
