Well yea so far as how you're engine is balanced, there are 3 options for a 5.0. there is a 50oz external imbalance (stock later 5.0s) an Internal balance, which has to be done by a machine shop, or its like a 28oz imbalance(early 5.0s) but apart from that spec there are weights to tweak that balance slightly. How would i know whether or not i need them?

You need to be sure which your rotating assembly is 50, 28 or neutral.
Did you get a build sheet with the engine?
If not, just make sure whatever you put on there matches what you take off, otherwise your engine will shake itself to death.

I bought the car with the engine built, I've just since had it rebuilt with some minor tweaks. It still accepts a 50oz imbalance flywheel, but what about those little counter weights? what are those for?

If they came with the new balancer, then they are used to balance it to whatever imbalance you need. As far as I know there should only be two of them. Neutral balance is using no weights, 28 oz is using the smaller weight and 50 oz is using the largest weight.

Okay so I got my balancer today, and it doesn't even have the little pin weights I was referring to, so hopefully this works!

Did you determine for sure which imbalance you needed before you ordered it. If not and it is wrong and you install it they probably won't take it back.

Let's hope you don't, but it does not have the extended keyway or HD hub for blower use.
