I have a 2005 GT the 3.8 V6 (non-supercharger) my head gasket blew. I am pondering if it is cheaper/easier to just get an entire engine or have it rebuilt. Plan to have taken to the shop monday. I was toying with the idea of dropping the supercharger version in it. If I bought that engine what amount of extra work would be needed or would it pretty much mount right in there.
