The most common issue is tires and you said that it was speed balanced? How long ago? By whom? When tires are balanced there are weights that are clamped to the rim. If the weights are loose and fall off, the balance does no good. The speed is another issue, tires are balanced for a certain speed and until you reach that speed, it is usually not in balance. Lastly it could be brake rotors or a CV joint or bearing that is bad.

I'm sorry to be the one to have to tell you this, but you are going to need a new engine. The connecting rods have welded themselves to the crankshaft, due to oil starvation. That is why it will not turn over, even with a new starter. I would take that starter off and return it for a refund. Just make sure it's clean and doesn't look like it has been installed'
