Really odd C4 flexplate!
Looking for a C4 for my '73 F-100 with 302, I found a nice one in what appeared to be a fully stock '77 Granada with 351W. I pulled the C4 along with the bellhousing, convertor, seperator plate, and flexplate.
Once home, I rebuilt the C4 and got stuff ready for the swap. Then...I took a look at the flexplate!! The only marking on the flexplate is stamped into the metal and says.... AOD!! What??
I thought the AOD tranny wasn't introduced until '81 or so! It IS a C4, so what is it doing with an AOD flexplate (if it is an AOD flexplate)?
My concern is that my 302 has the 28 ounce imbalance and the '77 351W also has 28 ounce imbalance. I thought all the AOD's had 50 ounce imbalance, which would make this flexplate wrong for a 351W setup. How did it get into this stock appearing setup? It's a mystery! Any ideas??
