I am a pro-manual tranny guy and don't own anything with an auto, but I've come into posession of a good 88 AOD and I have several Fe-C-6 cores laying about. For a fun project, I was going to chop the FE bellhousing off a C-6, CNC machine the AOD case and the C-6 bell and TIG them together. It was a slow day today so I played around with the tape measure and calipers and the bellhousings will line up well for welding, BUT all the FE flexplates I have laying around have 6 bolt holes and an AOD converter has 4 studs. Anybody know if there was ever a 4 hole FE or 385 series flexplate that will bolt to a small block AOD converter? I am not very well versed in auto tranny technicals. If it works, the hybrid AOD will be for sale.
I'm an idiot! All FE flexplates have 4 bolt holes. I have stacks of flywheels and flexplates and thought that my FE flexplate pile was the biggest. The biggest stack turned out to be chevy flexplates. I was sctratching my head trying to make a 350 flexplate fit an AOD converter. The FE flexplate fits the AOD converter, but there isn't enough room for the flexplate to crankshaft bolt heads. There's about an 1/8" difference in the offset of the FE flexplates to small block flexplates and those bolt heads just won't clear. I don't think this project will work after finding this out. I really don't like adapter plates much though. I started machining 6BT cummins to Ford adapter plates after a good friend that owns a diesel shop had alignment problems using other's plates. Some places making these plates just don't watch what they're sending out the door.
