I have a 302 currently in my 84 mustang. I also have a 351. I have no idea if it is a windsor or a Cleveland or a modified. I heard about the way to tell if its a windsor or cleveland by if it is a windsor it will have 5 bolt pattern on the valve cover and an 8 if its cleveland. How do i tell if its a modified? And what i thought about doing is taking the heads off the 302 and intake and put it on the 351 block. I was told this will work. I just want to know if its true and how to identify what 351 i have and if this will work will it work with only one kind of 351 or any of the three.
