Hi,
Looking for some advice. I recently rebuilt my 400 engine to put in my 67 FB Vert. It was originally from a 70 to 72 Grand Prix from what I was told. I bought Ram Air Restoration long branch headers. They suggested that I buy the heavy duty flanges from them as well as the oil filter adapter. I did that and I can't get the oil filter on because it hits the headers. I called and they said I needed a 90 Degree filter housing. I bought one rebuilt from Butler Performance. I still have the same problem. The filter is hitting the flange. I even tried a smaller filter. Any ideas?? Anyone experience this before? Please let me know. Thanks in advance
Mike
