Hi Everyone, I received my packed from PHS and I wanted to let you know what I came up with. My 67 did come with a 400 (YT). Unfortunately for me I think the news is not what I had hoped. Although the engine in the car was made Dec. 14th 1966 and the body was made the 3rd week in Feb 1967, the engine codes do not match. 05678 is the number I am able to make out on the left front side (passenger side)of the engine. My Engine unit number on my billing history from PHS shows 376031. Clearly not the same number. Still love my bird though...;-).Thank all of you for your help with my delimma.
