Hello All, I am reaching out to some of the more experienced rover engine guys here. I am going to rebuild a 1998 4.0 that I have. I am interested in converting it to a 4.6. I have read bits and pieces about the motors being identical with the exception of the crank and the connecting rods. Is this true? Has anyone done this kind of rebuild? Would it be better to start with a 4.6 P38 motor?
