360 A833 flywheel?????????

A 360 is external balanced as are the newer 318s. You can buy a new flywheel from Summit or Mancini, etc. About the only way you will find a used one is from a wrecked Dodge Ram 1500. I have the factory specs and engineering drawing of the placement of the 3 balance holes so if you have an internal balance flywheel and access to a machinist who is able to "trig" the pattern, it can be used. I have found that many shops do not have that big drill bit. It can still be done with a smaller bit but the drilling has to go deeper.
