Every engine here shares a 4" bore; displacement varies by stroke alone, which is the signature of a family built on one block with different cranks.
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.
