318 flex plate have same crank bolt pattern as 360?

Thats a good question, they checked it and showed it was balanced with that big *** weight they added to the face of it. So lets say cause the pie cut acts as a offset to one side for the converter and the platye acts as the weight?Its hard to explain.
I talked with my local hot rod guru and he said they did it the way for a stock x style so my other one wont work.
