I saw a post on Fordsix.com where someone drilled the V8 AOD bellhousing for the top bolt holes, and then used a 300 I-6 flywheel to bolt the torque converter to. Other than that theres no other way to do it that I know of. The bellhousing bolt pattern on the 6 cyl blocks is different from the ones the V8's have. They made a few 200 blocks with the V8 bellhousing pattern, but they are hard to find.
