Not once you factor gearing into the equation.

Sure there are trade offs that be made, but the 5.9 crate engine made 440 ft lbs at 4100 rpm with stock 9 to 1 compression, while the 5.2 magnum build with KB pistons at 10 to 1 and quench made 382 ft lbs at 4900.

Apples to apples that is a huge difference.
