He may have an engine that was built up with a mix of 427 and 428CJ parts. I am not aware of any intake that starts with the letters CJ. The factory 428CJ engines had a cast iron intake and the number was C8AE-9524-C in most cases. Not all 427 blocks had a 427 on them. If it is a 427 block it will have cross bolt caps on the middle three mains and you will see the 9/16 heads on the side of the block. Again a ,ot of peole do not know what they have when it comes to FE engines. Good luck, Keith
