TORQUE is the result of the effective cylinder pressure curve , cylinder displacement and crank stroke to bore ratio, the larger the bore the more effective surface area the cylinder pressure generated has to work against.
longer strokes allow the pressure to work against a more effective leverage ratio, and higher compression ratios generally result in higher average cylinder pressures during peak burn times which potentially allow more efficient use of the fuels caloric content.


think about this, a 350 has a 4' bore diam and a 3.48" stroke , that 12.588 square inches of piston surface area
think about this, a 454 has a 4.25' bore diam and a 4" stroke , that 14.210 square inches of piston surface area
that gives the 454 a 13% mechanical leverage advantage, a 12% INCREASED SURFACE AREA, OVER EACH PISTON, FOR CYLINDER PRESSURE TO WORK WITH, and approximately 30% more displacement, not even counting the larger more efficient splayed valves , thats in theory a significant advantage and why the larger engine easily produces more torque, its also why you seldom see 327 and 302 chevy engines being build vs 383-406-427 sbc engines, the larger displacement and longer strokes effectively produce more useable torque.
look even if you make 1.25 hp and ft lb of torque fron a 350 thats 437 hp and 437 ft lbs which is above average for a street 350, but simply building the larger 383 with the longer crank stroke and making the exact same 1.25 hp/ft lbs =478 hp/ 478 ft lbs
how crank stroke effects piston movement and acceleration, notice how the blue piston simulating the longer stroke provides both more volume included in the stroke and more compression at top dead center on compression
