This family is represented by a single engine in the database: 145 ci, 4 cylinders, a 3.465" × 3.858" bore and stroke.
All are undersquare — stroke larger than bore, favouring torque low in the range.
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.
