flexplate ?'s

I have 3 flex plates here. 1 from my aod 2 from c4's. the weights on the aod and big c4 plates have the same #s, the small c4 flex plate (which i need to use w/ small bellhousing c4) has a different #. How do i know if the small flex plate has the right weight? John

The C-4 is a 28.8oz balance and your engine is 50oz. You will have to have the C-4 plate rebalanced or get a new one made for the swap. The numbers are diffrent because the small one has 157 teeth on the stater ring and the larger one has 164 (same as an aod).
