New MP 518 O/D Tranny & Conv Small Block

nope. electronic ones started in 96 w/ OBD-II. and yeah itll fit any LA or Magnum small block. and at one point they stopped offsetting the 1 TC hole and started putting the 360 weights on the flex plate instead of the TC so they could use the same TC on either V8. They finally figured out that the flexplate was cheaper than specific TC's.
BUT the amount of weight on a 360 Mag is different from an LA.
If you were closer I'd at least be interested to come for a look. I would not mind the 518 in place of the 727 in my 83, 3/4 ton.
