I have a 66 mustang coupe that i am converting from a 6 cyl. to a v8 302 from a 70 mustang coupe. I have the motor in the 66 but, i am having some issues with putting a rear main seal in. Of course, I drained the oil, but needless to say this was 50/50 water and oil. I know that is not a good thing. Then i can not get the oil pan off becuase it seems as if the oil pump is in the way. Does anyone have any advice on anything, because i am clueless and tired of this conversion project. All i have run into is problems. Thanks, please get back to me.
