installing 883 I have 440source flywheel question

Hi there I have a 72 360 motor and I have a 883 that will be running behind it. I bought a flywheel from 440source.com seen at: http://store.440source.com/1045-Billet-Steel-Flywheel-New/productinfo/113-1014/ which some people on this forum have said works great. My question is if I can just bolt this on and run with it without pulling the crank and having things balanced? I'm not looking for high performance low quarter miles, just a smooth running motor with a 4 speed behind it. Thank You!

If there are any other tips you might have to make my swap work the first time, fire away!
