Cracked 360 Magnum Flexplate

snailpower said
My PP balancer is balanced for the 360 yeah (has an offset weight on it), current plate is weighted (stock mag plate) and converter is neutral from the 318 that came out. I would think a neutral plate would throw it off no?

yes it will
I believe B&m quit making a Magnum 360 904 flexplate. You could get a neutral 904 plate and buy your converter weighted for 360 magnum.
