I hear ya now. Heres a pic of Vaughn Gittens 69 Stang with a 5.0, the whole front of this car was customized to fit this engine and huge tires.
Hmmm, I'm going to have to look and see how much (if any) bigger the 5.0 is over the 4.6. The 4.6 DOHC should fit in a 69/70 with the strut towers removed from what I understand.
