Default 401 vs 432 torque ratings???

Chart has 432 rated at 336 lb-ft @2000 rpm and the 401 at 348 @ 1600.

Why does smaller engine with shorter stroke have more torque?

Is the 432 a Magnum????

I have a 401 but have a serious craving for TORQUE!!!!

Edit to add Wikipedia quote:
"In 1973 & 1974 there was also a 432.2-cubic-inch (7.1 L) version with enlarged crankshaft journals (4.875 in × 3.86 in (123.8 mm × 98.0 mm) bore and stroke). The 432 was a 401 with a 478 crankshaft. It produced 190 hp (142 kW) net at 3200 RPM and 336 lb⋅ft (456 N⋅m) net torque at 2000 RPM. The 432 was a Magnum engine though it was never designated as such."
