The truck originally had a worn out 302 and a C4. Bolting in the new 5.0 was simple, as it's the same engine. As far as the AOD transmission, it was just a matter of moving the crossmember back on the frame and lengthening the rod for the shifter that runs from the column down to the transmission. The two transmissions were within 3/4" length of each other, so I was able to
reuse the driveshaft.
As far as waiting up that engine, the factory Grand Marquis engine wiring harness drops right into that truck like it was made for it, battery harness and all, and it's just a matter of hooking up proper powers and grounds for the computer.
