What varies across the family

Both bore and stroke vary across the family, so these are separate castings rather than variations on one block.

1 of 3 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.
