Also someone said something about displacement pretty well being mandatory for torque. That is only part of the picture. Even if you have a 440, compression ratio, breathing and more goes into it than just sheer CID. As compared to similar displacement engines from any brand, the long stroke of a slant gives it a huge advantage over other engines.
Look at a 300-6 vs a 302 ford in a truck. The 300 was rated for more towing capacity even though it is 2 cylinders less. The combo of bore X stroke is quite different between them. A 302 is a quicker revving engine, better for HP at higher rev's which isn't ideal for pulling power
