What varies across the family

This family is represented by a single engine in the database: 308 ci, 6 cylinders, a 3.8125" × 4.5" 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.
