What varies across the family

This family is represented by a single engine in the database: 365 ci, 8 cylinders, a 4" × 3.625" 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.
