swap

I am aching to take on swapping a 4.6 into my 68 mustang but i need some help.I know the wiring is going to be pain and i'm going to have to cut the shock towers if there is somebody who knows what else i need to do i would really appreciate the comments.Also i would like to know out of curiosity how much a basic 4.6 weighs. <img border="0" src=smileys/smiley5.gif border="0">
