Look em up and compare to real gross HP numbers for a 273-2 and a 318-2. Like a poster said, we are comparing motors with the same go fast parts, only thing different is the bore. Now let's compare a 10:1 273-4 to a hypothetical 10:1 318-4 (cheaper to build new than a 273-4). There will be no comparison with +20%, or 45 more cubes. I stated there is nothing a 273 can do that a 318 can't do better. Sure the 273-4 has +5 hp but when will it catch up to a 80 ft/lb torque advantage? Gearing is not part of the comparison. Post up what you find, it will be interesting for the thread.
