What varies across the family

Stroke is constant at 3.2677" across the family — the displacement spread comes from bore, so these share a crank and differ in the block.

Compression spans 8.9:1 to 10.5:1, so fuel requirements differ meaningfully between members — worth checking before assuming parts interchange.

1 of 8 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.
