5.9 magnum or 440

there is no replacement for displacement

but then again, the magnum is about 3 decades more technologically advanced

but then again, the 440 would need a complete rebuild so the parts can be handpicked for the exact style motor you want

but then again, the magnum could be as much as 200 pounds lighter, which will need less horse power to move, less brake power to stop and most likely handle better

but then again, the 440 is a 440

but then again, the magnum might need a lot less work to bolt in the then a 360



I guess there area couple of things to consider ;)
