I'm looking to put an AOD transmission up to my 351C. So far, all I can find doesn't convince me that the flexplate for a 5.0 will bolt up to the 351C. Are the hole patterns on the crankshafts the same for both engines? What would their dimensions be? (number of holes, diameter of holes, bolt circle the holes are on).

Thanks in advance!

I am pretty sure the bolt pattern is the same, but the amount of imbalance may be difference. The 351C should be a 28 oz. in. set-up. The 302 came 28 oz. in or 50 oz. in. 50 oz. in. was the late model 5.0 I think.

 

Yeah, the imbalance is 28oz. for a Cleveland and early 5.0s. The later 5.0s require the 50oz. The AOD needs a 164 tooth flexplate. I'm now wondering if the torque converters bolt up too. I guess it's time to start asking the people who sell this stuff what to do...
