The Real Difference Between Mopar 440 And 440 Magnum Engines
By MIKE SHUTT
Mopar, or "Chrysler Motor Parts Corporation," has provided the company with engines for decades, such as the Mopar 440 and the 440 Magnum.
While these engines are roughly the same, one provides more power than the other. The standard Mopar 440 generated a rather impressive 350 hp and 480 lb-ft of torque.
The Magnum was able to increase the engine’s output to 375 hp and the same torque. Over time, Mopar increased those Magnum numbers even more to 390 hp and 490 lb-ft of torque.
The 440 was a four-barrel engine, but Mopar also created a six-barrel version of the Magnum called the Six Pack that allowed these power increases.
