...............before i get hit with the typical "search is your friend" or other such stupid replies, I have searched and i cant get a straight answer. Some say yes, some say no, others say only certain years. i would like to know if a 325i top end from a 90 e30 will bolt to my 84 528e bottom end, and if so, how much do i need to mill the head? thanks in advance for helpful replies!
