So if I bought those weights could I use a neutral balance flexplate then weld those weights on my converter to balance it out? I have a 9" PTC 3500 btw.



Heres what you want to do, scout the boneyards for a 360 magnum flexplate with the weights "ON" it, then you can run neutral balanced converters, look at the later blocks (1998-2002), B&M no longer makes the flexpate for the 904 too 360 magnum, just the 727 too 360 magnum, now thats not to say the 727 flexplate won't work .
