The weight differance is mabey 20# tops while the cube differance is 57 cubic inches, 20 LBS is not nearly as significant as 57 cubic inches



You're right: if a car had 10 lbs per hp (ie. 400hp in a 4000 lb car) and the engine was producing 1hp per cu in, then 57 cu in = 57 hp which would make up for 570lbs of car weight! ...or conversely you would have to use up 2hp of the 57hp you gained with the 440 to deal with the extra 20 lbs leaving you with a 55hp advantage.

.....The aforementioned numbers are generic, but you get the idea.
