They make AOD shift (reprogramming) kits so you can go with more power. An example http://www.transmissionpartsusa.com/AOD_Transmission_shift_kits_s/12284.htm

351 CID Windsor V8 1983–86, 351 CID HO Windsor V8 1984-86. You will have to change over the electronics and a few other minor things to make it work.

Yes it will the 351W is a small-block, up to 1997 when it was discontinued in favor of the 4.6 but Ford began using fuel injection in 1987

Not to be confused with the 351 Cleveland, a completely different engine

Wow I learned something today! I had no idea they made the 351 that long. Thanks Fordnut. Since I learned something already today I can turn my brain off and look forward to the weekend, LOL

Ahhhh ok. So I'm not totally losing my mind, LOL.

It had a different cam and heads, and valves, from '86 to '97 for the cars sacrificing some low-end torque for more HP for the cars

Well that does make sense. I thought the Mustangs had 302's in them until 1993 when they ended the Fox body? The 351 in the crown vic, Marquis, Town Car and Super Duty trucks makes sense.
