Here's my $.02... the 6.9/7.3 have the same SAE bellhousing. I'm not sure what number it is. The PSD probably has the same bellhousing pattern but I'm not sure since I haven't had any PSD apart.
351M, 400, 370, 429, & 460 Ford gas engines have what is known as a "big block bellhousing pattern". *Exception*: 1973 400s installed in full size Fords with FMX transmissions (transmission code PHB-AD) had a small block bellhousing pattern.
Windsor engines (221, 255, 260, 289, 302, & 351) and 351C (Clevelands) have what is known as a "small block bellhousing pattern". Fords large straight sixes (240 and 300) also have this pattern. *Exception*: Pre-'65 small blocks (221s, 260s, and 289s up 'til mid '65) have a 5 bolt bell housing. In the middle of '65, Ford switched to the now-standard six bolt design.
FE and FT engines (332, 352, 359, 360, 361, 389, 390, 391, 406, 410, 427, & 428) have yet another bellhousing pattern known as a "FE bellhousing pattern". This bellhousing is quite round.
Small Ford straight sixes (170, 200 and 250) have yet another bellhousing pattern. It is smaller then the other three bellhousings above.
C6 transmission cases where made with small block, big block, and FE bellhousing patterns.
E4OD transmissions where/are made with small block and big block bellhousing patterns.
The Ford ZF has a big block bellhousing pattern.
When Ford installed the 6.9 and 7.3 IDI Diesels, they used a cast iron adapter to convert the SAE bellhousing to the big block bellhousing pattern. That goes for automatic and manual transmissions. I'm guessing the PSD is the same way. According to Diesel_Aggie, the PSD does use the adaper plate. Thanks Diesel_Aggie.
Last year I searched the internet to see if I could find blueprints for SAE bellhousing and flywheel dimensions. The only thing I found were a few prints on the Kubota web site. ( www.kubota.com ) Some of their engines use the smaller SAE bellhousings. If anybody knows where I can find blueprints/drawings for SAE bellhousings, please let me know.
I have no V10 experience but I'm guessing it has the Ford big block bellhousing pattern. Keeping it the same would allow Ford to use current production transmissions without having to make a new transmission case.
Just out of curiousity, does Dodge use an adapter plate on the back of the Cummins? Or did they make transmissions with the same SAE pattern as the Cummins.
