Well big blocks are, in most cases a way bigger cylinder bore, and sometimes a small stroke on the crank, not always, for example, take a 383 chevy, its a 350 with a bigger 3.75in stroke, and bored .030, and compare it to a bigblock chrysler 383, which is 4.25 bore, and small 3.36 stroke, and torque, what big bore, and small stroke created, was a high reving somebatch.
