My son wants to put an AOD in his 68 stang next week. I have a line on a good one out of an 85 lincoln.The stang has a some-what built 351w about 410 hp? an 8" 4-11 lincoln locker. Used mainly for the street but it will see a few trips to the track!! What stall would be good on the street and what brand would anyone reccomend?
As a side note what flex plate do I need?------------------

We have good used Flex Plates in stock for $25. Contact JPT via e-mail [email protected] or 517-663-0578 for stall converter needs. There are two types available. With or without lock up.
We just installed a JPT ten inch non lock up over the weekend for a customer and the is still peeing in his pants. The car went from not being able to turn the tires to smoke city. Driveability was not hampered.  ------------------

Jim, Were you looking at the C4-to-AOD article? There's an entire section on it. It's reproduced below. Dan Jones Flexplate Diameter and Balance
------------------------------
One of the more important parts of the swap is to choose the proper
flexplate for your application. The integral bellhousing AOD requires a flexplate
with 164 teeth (approximately 14 1/4" diameter with an 11 7/16" torque converter
bolt pattern) for proper starter placement and converter compatibility. The
C4, however, uses a detachable bellhousing that is matched to one of three
different flexplate sizes (148, 157, and 164 teeth). The 148 teeth
flexplates are comparatively rare, having been used in cars like the V8 Mustang II.
The 157 teeth flexplates were generally used in 289/302 small and mid-sized
cars, while the 164 teeth flexplates were used in 289/302 full-size cars and
351W/351C applications. The C4 164 teeth flexplates and the AOD 164 teeth
flexplates will physically interchange, but there are two balance weights
(pre-'81 302's use a 28.2 oz-in balance weight, '81-up 5.0 HO's are 50
oz-in), to be concerned with. I haven't had a chance to verify but I think all
351W's and 351C's used 28.2 oz-in balance factors. Also, the catalog I looked at
suggested that 1981 and up non-HO 302's are still 28.2 oz-in (at least to
1990). Anyone know for sure? In my case, the flexplate in the 1971 Mustang
came with 157 teeth and a 28.2 oz-in balance factor, so it required
replacing. Since they both have 164 teeth and 28.2 oz-in balance factors, I was under
the impression that flexplates from either a 351W w/AOD or early 289/302 w/C4
from a full-size car would work. Looking through the books at the parts store
showed that these were not common part numbers, and listed the 351W part as
working with an AOT, not AOD, transmission. Not knowing if the AOT
indicated a subtle variation that I was unaware of, I decided to order the early
289/302/C4/full-size part (OEM D1AZ-6375-A, Saginaw XF15). This turned out
to be a mistake. When we put the converter and transmission up to the engine
for a fit check, the modeling clay we had put in the crank pilot showed the
converter snout was barely making contact. Apparently there is a difference
in flexplate depth. It all would have bolted together and the starter may
have even managed to reach the flexplate teeth, but there would have been no
support for the converter and the starter would have eventually chewed up
the flexplate. Procuring a 351W/AOD flexplate over the holidays turned out to
be an ordeal (dealers wanted 14 days), but it was required for proper converter
snout to crank pilot placement, while retaining the proper diameter and
balance. We finally found a transmission supply house that had the right
piece. We put the 351W/AOD next to the early 289/302/C4/164 teeth part and
there was a difference in height. Since then I have checked some
aftermarket catalogs and they show the same part number for both applications, so buyer
beware. The part we finally obtained was from Sealed Power and corresponded
to OEM E0AZ-6375-A (164 teeth flexplate, 28.2 oz-in balance factor, 351W
with AOD applications). If you're swapping an AOD onto an '81 or later 5.0,
you'll need the AOD flexplate (164 teeth, 50.0 oz-in balance factor, for 5.0
with AOD applications). I think the OEM part number for the late 5.0/AOD
is E2AZ-6375-A, but I didn't verify this. In a pinch, you could swap (weld)
balance weights between flexplates to get the proper balance factor. If you
choose to do this, remember that the balance factor is a moment of inertia
(distance time mass) so keep the product of the distance from the weight to
the center of the flexplate and the balance weight (plus any additional weld
weight) equal to a constant (either 28.2 or 50.0 oz-in).

>Go to this guy's site. He is FULL of that type of information.
>He loves to build the "unique". His name is Dave WilliamsNo need to go to his site, I've been to his house! In fact,
he has my 351C block and 400 crank at his shop, waiting for
me to finish the heads and pick a cam. Dave will also be
doing the crank work on my little Buick/Rover aluminum V8
(he's got one of his own that he plans to do for a scratch
built Lotus Super Seven clone). I've got the combo worked
out but, at this point, I'm looking for opinions on how well
the off-the-shelf cast 255 V8 or Ford V6 pistons will hold
up to the power and RPM. >D&D Fabrications specializes in those engines. 810-798-2491. Yup, Dan Lagrou is the man. He recommends the Ford 255 piston
(3.68" bore +0.030"): SilvoLite p/n 1176
Nylen p/n 1134P
Sealed Power 9039P (not sure if this one's still available) Any idea if one of these companies is likely to make a better
piston than the others? A 2.8L Ford V6 piston with a 1.516"
compression height would also work (Perfect Circle 224-1999
+0.060") if I use a 2" journal 5.7" rod instead of the Buick
rod. Thanks Much,
Dan Jones

He accidently replied to his "oddball Ford piston" post in here, no worries . ------------------
