1979 mercury monarch
 

I have a 1979 mercury monarch i am wanting to build up. its something you don't see built up every day. it has a 250 inline 6 and an automatic. I'm wanting to drop a 302 or a 351w into it. i know v8's were an option in these cars but i need to know what all i have to change to swap a v8 in place of the 250 inline 6. Where to get mounts and electrical if aby i need to change. thank you for the help!
