Need help identifing this Ford balancer

I need some help identifying this balancer, it came off a Ford 357W in a '74 block. I'm putting the motor together and just want to see if I can put on a Ford Racing 28oz balancer on it instead of this stocker and so I know what flywheel to put on.....I researched the 4 numbers on the front "6316" and came up with both 5.0 and 5.8L engines and obviously it won't work with a 5.0 50oz engine if it's for a 28oz 351W so just making sure.....


What's the difference between a "28.2oz" balancer/flywheel and a 28 oz balancer/flywheel?...Does that .2 really matter?
