Now to make it squat Hispano reduced the length of the rods but had to fiddle with the angular displacement of the slave rod bearing to get a miss on the cylinder mouths. The engine is a 60º V but the angular displacement of the slave rod "big-end" from the master rod is 67º and so the stroke this side is lessened as TDC occurs therefore 7º before the crank pin is on the cylinder centre-line.

Amazing stuff - mechanical engineering at its pinnacle. And all this with merely a pencil and slide rule!
