5.9 Weighted Flexplate

So you are doing what? Carbureting a magnum? Putting it against a 727? I see no reason you can't use the OEM weighted flex out of your truck

My flex plate is neutral, like a 318 would be. The trucks 518 converter is weighted. And that is my problem. I'm using a 727 instead of the 518 and my 727 is neutral balanced.

If anyone needs a good 518 trans, I would happily trade it for a weighted flex plate! I had a hard time through school trying to save up and buy/rebuild the 518's after I tore them up. Now I can't even sell this thing for $250. The demand is gone I suppose
