Yes, you can even get an external balance SFI harmonic balancer should you need it for a 10 second car....but of course internally balancing the motor will simplify things down the road.

As mentioned, it is allowed. But aside from the advantage of easier to find neutral/internally balanced dampers flexplates and converters, I was always told that internally balanced assemblies are easier on the crank and bearings. It's probably more relevant to higher rpm combos, but something to consider nonetheless.

You can also take a externally balanced motor (such as a 360 SB) and have
it internally balanced (does use more heavy metal). But it can be done.
