AOD Swap Info From the Archives
Editor's Note:
References below for 50oz and 28oz flexplates are reversed.
Early engines had the 28oz imbalance on the flexplates, the later engines had the 50oz.
As usual, you are ultimately responsible for changes you make, so verify all information
before proceeding.

Please SOMEBODY put this in the FAQ and the archives!!!! LOL!
OK, first the #2 front crossmember has to come out. This is the memeber
below the bellhousing.
For a car running EFI, USE only the late MUSTANG AOD. Get the shifter,
kick down cable or rod all from ONE car. See the parts list at the end.
For a Carbed car, most of youall here, use the Lincoln Mark VII or
Continental thru 87 AOD, The linkage uses the stock mustang II shifter,
uses the stock MII kick down rod and you get a slightly better stall
speed converter because of the lincolns extra weight.
Flexplates are a problem until late August. No one has an old balance
weight flexplate for the 167 tooth AOD. Ford switched engine balance
weights from 50 oz inbalance to 28. oz imbalance in 1981. All 302
engines before 1981 are old/heavy balance in the flexplate. So the need
is for the new 167 tooth in the old baance (50 oz) Mcleod clutches just
released a flywheel for manual trans cars that is modular. It allows for
0 balance(nuetral), 28 or 50 oz imbalance configurations. When the
flexplate verasions hit in august, this is going to make the swap a
sinch. A competent balance shop can reconfigure a new 28oz flexplate to
50 oz but it is hard to get just right.
Driveshaft, v-6 MII with a v-8 yoke. Use std MII v-8 u-joints front and
rear on the v-6 shaft. I use the motorsport t-5/AOD/C-4 slip yoke it
fits the MII c-4 and all other trans listed above. The v-6 shaft is 1.5"
shorter and is perfect.
Cross member/ tranny mount. Us ehte stock AOD mount. Use the MII double
hump pre-1977 crossmember. Now the hard part to explain. The factory MII
crossmember straddles a tab on each side that is part of the engine
subframe. This tab is not moveable whithout major welding and cutting.
Instead, move the crossmember behind, to the rear of the car, the tab,
fabricate a tube spacer to fill the gap where the tab used to go. Now,
take a longer bolt, grade 8 hardened, run the bolt thru the tab, thru
the crossmember, thru the spacer, and out toward the rear of the car.
LAstly, take a heavy (I used 3/16 plate) "L" bracket and bolt it to the
floor at the end of the crossmember. Bolt all the pieces listed like a
shish-ka-bob on the bolt. Lay under your car and look at the crossmember
and you will understand the crossmember goes behin the tab and needs
reinforcement at the rear of the relocated crossmember.
Now, PLEASE dont everyone gang up on me about the header thing again.
Headers will not fit out of the box, in a house, in a boat, in a car or
a train. With socks or with locks,I dont like green eggs and Ham! Sam I
am!!!
Dr Duess has tried this too!!!!! LOL! the trans pan on the AOD is
exactly DOUBLE the width of a C-4. A custom shortie set is the only way.
Ported exhaust manifolds are quieter and fit. And will flow within 10%
of 1 1/2 headers. Use 2 1/4 duals and youll never know the difference.
I have the Lincoln AOD in the KC with a late (85-86)vintage engine. I
have yet to fiure out the kick down for the EFI with the Lincoln trans.
The Mustang AOD and shifter will fit perfectly and work great for an
EFI car. My mistake.
