Worked out from FAA Aviation Maintenance Technician Handbook - General (FAA-H-8083-30B), piston displacement and 2 other sources.

How this is worked out

4 steps
  1. One cylinder sweeps pi/4 x 86^2 x 86 = 499557.2142 cubic mm.
  2. Times 4 cylinders = 1998228.8569 cubic mm = 1998.23 cc = 1.998 L = 121.94 cu in.
  3. Bore/stroke = 1, i.e. square.
  4. No chamber volume given, so the compression ratio is not reported.
