351W AOD Flexplate
1980 Econoline 351W 2V C6 (ditto 1975/79) / 1981 Econoline 351W 2V C6 except CA / 1982/86 F150/350, Bronco & Econoline 351W 2V all A/T
1984/89 F150/350, Bronco & Econoline 351W 4V & EFI all A/T
And, since this is a 1971 (D1ZZ) part number, it was used in myriad 1971/79 351W cars, none of which came with AOD until 1980.
It's also listed for 1979/80 cars with 302/C6.
I don't know the years/models this all works out with out looking over Bills post and to say I don't really care as I am not into this swap.
We know the EDO did not come out in the trucks till later years than what some want them in. Kind of the same fro the 351 if I follow this right.
We do know you cant use a 302 plate with the ADO with out issues.
So the person doing the swap would need to know what year/models (cars or trucks) the 351/ADO came in (thanks Bill) and find a plate for that setup to use in your swap.
Not hard in my book based on Bills information if I read it right.

1980/89 LTD/Crown Vic/Town Car use a specific 351W/AOD flexplate as does the 302 in all these vehicles. AOD introduced in 1980 Passenger Cars.

1980 LTD/Grand Marquis/Town Car/Mark VI 351W except C6 / 1981/89 LTD (name changed to Crown Victoria in 1983)/Grand Marquis/Town Car 351W .. parts catalog doesn't mention the trans type.

The January '17 Hot Rod magazine has a fix-it article on an AOD in a '67 Mustang. Lots of pics, and they show how the cable travel was fubar'd, along with the usual go around, and in the end they made it shift right.

Reference to post #6 was a typo. Post #15 was my first post in this thread.
The OP said he installed a 351W in a 1984 F150, but made no mention of what vehicle the 351W came from.
When you consider how long the 351W has been around, it could have come from anything.
post #6 is late 80's cop cars with 351 & AOD
Then you list D1AA-6375-A for post 6 but list F100/350, Bronco & Econoline flexplate for that part number. Was the Bronco & Econ a 351/AOD?
Yes I did ask about the cars only because you listed 1980/89 LTD/Crown Vic/Town Car use a specific 351W/AOD flexplate but came back with non that were 351/AOD list. You did say the book did not say what auto it used so?
So is D1AA-6375-A used with a 351/AOD and if not what plate is from a cop car is?
I do thank you for the help in tracking this down.

I never said anything about cop cars (police cruisers), as the catalog makes no mention of them.
I listed the D1ZZ-6375-A applications (post 17) and the EOAZ-6375-A applications (post 21) which the catalog says 1980 cars except C6 then fails to mention which A/T for 1981/89 351W cars.
So I went and looked at the applications for 1981/89 LTD/Crown Victoria 351W .. all came with the AOD
1980 is a mess, some of the above cars with 302 came with C4 or FMX or AOD. With a 351W, could have a C6 or FMX or AOD. Only the 1980 Town Car/Mark VI 302/351W came with AOD only.
Mr. Clean (ctubutis), the Oklahoma Kid (Gary Lewis) and I have the 1980/89 light truck parts catalog, why don't the rest of y'all?
2 finger typing all this crap is a pain in the backside.

Did it come from a 1969/89 car, or a 1975/80 Econoline, or a 1981/96 F150/350/Bronco/Econoline or a 1997 F250 H/D/F350?
Since we don't know, there shouldn't any speculation on which flexplate is supposed to be installed.
Man what a messed up way to make motors, switch the balance weight between years of the same size CI motor.
You know after thinking this over if he has a fly wheel that is the right balance that the starter works with and the converter bolts up to it might be best to use spacers between converter & fly wheel so the converter stays inserted in the pump.
IIRC with the converter fully seated in the pump, trany bolted to the motor the converter should only pull up to the fly wheel about 1/8".
Thanks Bill for the lesson

I just (today) bought my first Ford ever, 1985 F-150 with a 351W. It has a C6 and I would like to swap to an AOD. I don't anticipate ever beefing up the motor anything beyond some mild upgrades (heads at the most? doubtful though). might do the edelbrock carb efi conversion, but I head good things about the carbs on these motors. I'm mostly after fuel economy and it sounds like picking up the OD is the single biggest benefit.
Would I need to swap my flexplate for an AOD since I am starting with a 351W? I assume I will need a different torque converter too. Can I pull an AOD out of an 85-91 F-250 and just bolt it in my F-150, or will I need further modification such as to the driveshaft? Things like different brackets or cables, while I need to know about, are a minor concern. Mounts, subframes/brackets, and driveshafts are the big concern.
Thanks in advance
