Theirs actually a lot of adapter plate kits out their but thier all over 600 the cheaper way that i went was buy a ultrabell bellhousing which runs around 300-330 depending on where your buying it from. If you can find however an old ford econoline van or pickup that has the stock 460 and AOD you can use that. Their kind of hard to find but their out thier even the older Ford RV's ran them.

AOD gives me overdrive so its a little more streetable and a little better gas mileage. Plus you can build an AOD to take more than 800 horsepower so it can be just as strong or stronger than a C6.

Early to mid 80's econoline vans had them in select big block optioned vans. You have to watch that its not to new because they switched over to the AODE and from what i've seen they don't have a removeable bellhousing. I've seen one both types in these vans by me and both where bone stock factory optioned vehicles. Easiest way to tell is the shift pattern on the steering column AOD's have PRN(OD)D1.

No i have a 460 motor out of the same van.. usually they are in work vans like the centurion.... it is usually referred to as a fith wheel van.. they are massive and i was told that the last time the van was driven, he could actually powerbrake the thing an spin the duallies....he told me he was junking the van and bam i got my block and tranny....

http://www.campbellenterprises.com This is the website where you can find the JW Ultrabell bellhousing for the AOD. Plus they make a lot of other bellhousings for many combinations of motors and trannies. I know of one van that a guy is parting out but is keeping the motor and tranny. It's a 3/4 ton ford van and its marked as an econoline. The only problem was it was an 89 and had the AODE.

AOD-E? You sure you don't mean E4OD? That's the only tranny I've seen in older F and E-series trucks, the only exception being the 4R70W in my brother's '97 V6 E250. The E4OD is massive, with a pan spanning almost the length of the tranny, and was used on 300's (my '95 F-150 had a 300/E4OD), Windsors (the '94 van I got my 351 from had an E4OD), big blocks and diesels. You can tell this tranny from AOD's and C6's from inside the vehicle by the OD OFF button on the shifter stalk.

I'm rather surprised an AOD was ever installed on a 460. Not saying you're wrong, as I'm by no means an expert on the subject. I just didn't think one would be strong enough, and have never heard of one with the big block bellhousing.

So far the AOD has been fine until i can get a chance to build it up a little more. http://www.lentechautomatics.com/rwdmodels.html Lentech has probably one the best selection of parts for Ford overdrives you can even get fully built AOD to with stand 1000 plus horsepower.
