I like boobs!!!
I'm going to be getting a 4.6 from a junkyard from somewhere for a complete engine build. I have the 2 valve 4.6 and want to build a 4 valve. From what I've researched it shouldn't be that big of a deal mechanically speaking. As this is my first Ford build (I'm used to my good 'ol turbocharged LT1's but this stang couldn't be passed up) I would appreciate any advice that anyone has regarding block and cylinder head compatiblity regarding years of manufacture.
