IS there any physical difference between the La360 vs. magnum 5.9 Crankshaft???

Now on the other hand, we ALL know power is addictive, especially horsepower...and if you get the feel for 10lbs, your butt callouses will get thick and you'll want more...and eventually you'll run it to beyond the capabilities of the stock rotating assembly, at which point in time, the crank won't matter because you'll probably crack a stock hyper piston.
