What varies across the family

Compression spans 7.5:1 to 9:1, so fuel requirements differ meaningfully between members — worth checking before assuming parts interchange.

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.
