Not really an FAQ, since it goes beyond stock Opel parts, but I though this might be interesting to the engine builders out there. While cleaning up yesterday, I came across numerous sets of connecting rods and thought a comparison was in order. The Crower rods for a Ford 2300 are reasonably cheap, very strong, and only require the big end being narrowed by .013" to fit directly to an Opel crank, Ford bearings and all! The small end was spec'd at .912" pin diameter, and custom shorter pistons can be ordered with the correct compression height to fit perfectly in an Opel engine.
