Help with ID'ing factory converter (pics inside)

Less than 2000 stall. The weights are welded in the wrong place for a 360 unless they were trying to copy the 75 up triangular weight. The 74 down converters had 2 weights. 1 on each side of the mounting pad. I would get a different converter with the proper weight/ weights on it. Or grind those weights odd and get a B&M 360 flex plate for a 904 or 727 whichever transmission u have. Kim
