I just finally got done building my engine a 302 and the engine i built i did not take apart tand it was not in the car when i bought it. So i dotn really know what all teh random threaded areas are liek the oil pan ahs a big hole in it and the intake has 4 threaded holes and a few places on the black ill get pics by tomaorw if that would help people.
