You would need the engine complete with bell housing and tranny with main wiring harness and ECU with motor mounts and all that happy hooey. Pulling the old engine and installing the new engine, quite some time for pre fitment, and fabrication to install. If you want a V8 it might be your best bet to trade in the 6er for a GT, if you want to go that route.
Since there have been so many people that want to keep their beloved V6 instead of trading up to a V8, I found a site that makes it like a turn key operation for swapping the six for an eight. FINNALY! just wish I could remember the site. Do a Google search and you should be able to find this company offering the easy transition.
