Default Underdrive pulley question

I am installing my powerbond underdrive pulley and the snout is keyed but the crank snout is not, is there a reason for this? Also why is the underdrive pulley about 1 pound heavier than the stock won't this negatively affect the engine?

It doesn't need to be keyed.

I don't know why it would be, are you sure you have the right one? Mine is a March and it doesn't have a keyway from what I remember.

its keyed in case you wanted to key your crank to match it, say in a supercharger application....
