I'm still on the hunt for a 5.0 HO for my 90' T-bird. The only problem is that Thunderbird 5.0 are not all that common however 87-95 Mustang 5.0s seem to be in great supply. I've been told that the Mustang HO has inherent differences that make it difficult to put in my T-bird. Aside from the fact that I'm gonna need a new K-member (as I currently have a 3.8 L), can I get a Mustang HO and somehow convert it (crame it in ) to fit in my Thunderbird? Thanks to anyone who can help or anyone who has ever undertaken this swap
