      just remember the 360 is externally balanced....either you need a weighted flexplate OR a weighted converter ....one or the other....

      so yes the 318 flexplate will work if you use a weighted converter....and make sure the flexplate and converter have the same diameter ...aka bolt circle....

        We just installed a B&M 10239 ( externally balanced 360 with 904) on my sons 78 Magnum. I forget the part# for the same engine with the 727. Its heavy duty, overkill for the street, but not much out there if you want to run an unweighted converter. We found one on eBay, never used for about $85.

        I have used stock flexplates for $5 plus the ride if you are using the factory weighted converter. If you want an aftermarket converter run the B&M scalloped 360 balanced flexplate.

          I'm not running anything right now because I don't have a car. If you use a factory torque converter use a factory flexplate

          There are two sizes of converters from the factory. 10.75 and 11.75. different bolt circles.

          The six cylinder used a different flexplate and the Hemi had an 8 bolt plate.
          Some of the 67 and down flexplates had a smaller pilot (center hole).
          Other than that from 68 into the 80s all mopar v8s used one of two factory flexplates. ALL 6 BOLT CRANKS HAD THE SAME BOLT CIRCLE! If you keep the two (10 inch and 11 inch measured diagonally across the converter bolt holes) in the shop you will always have the correct one for a 904 or 727 transmission. Also note that in some cases a 904 and a 727 use the same flexplate. You either had a 10 inch converter (smallplate) or an 11 inch converter (large plate)
