This family is represented by a single engine in the database: 231.9 ci, 6 cylinders, a 3.7598" × 3.4803" bore and stroke.
All are oversquare — bore larger than stroke, which favours revs over low-end torque.
Each engine page carries rod ratio, mean piston speed, bore/stroke character and cylinder head specs where published, and links into the calculators with its dimensions already filled in.
