Every engine here shares a 3.248" bore; displacement varies by stroke alone, which is the signature of a family built on one block with different cranks.
Compression spans 9.6:1 to 11.65:1, so fuel requirements differ meaningfully between members — worth checking before assuming parts interchange.
2 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.
