Both bore and stroke vary across the family, so these are separate castings rather than variations on one block.
Compression spans 10.5:1 to 14:1, so fuel requirements differ meaningfully between members — worth checking before assuming parts interchange.
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.
