1965 barracuda 6 to v-8 swap

Hi and thanks to all of you this site has been great to a newbie like me. I am considering buying a 1965 barracuda slant 6 auto on floor it is not running so I figure this is a chance to mod one,would like to go fairly radical hi perf 360 727 sure grip some good rubber in a plain wrapper . suggestions ? or if this is an original car is it worth getting it running and modding the 6 .comments welcome.
