Last week my 2003 Mach 1 flipped over after a lower control arm bolt came out on the highway after the dealer replaced my lower control arm. My car is totaled. The engine still runs fine. I was wanting to know how hard would it be to put the Mach 1 DOHC engine in my 95 T-bird? I was already building a 98 mark VIII motor for it. So I have all the wiring and sensors for the 98 Mark VIII motor if needed. I would really like to use the Mach 1 DOHC motor instead because of the better heads on the 03 motor.
