Got my Rebuild in and Happy with the Results
Just thought Id share, the headers I purchased are a really tight fit but are the only ones that are built specifically for the 66 thunderbird. I actually ended up having to fab 1/4" engine mount spacers to raise up the engine to give the headers the clearance I was happy with from the inner fenders.
