What varies across the family

Compression spans 10.5:1 to 12.5:1, so fuel requirements differ meaningfully between members — worth checking before assuming parts interchange.

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.
