Either a bad battery/starter terminal connection, or your solenoid is out. You can by pass the solenoid with a screw driver. Touching it to the main terminal in the center, and the inside small terminal, nearest the motor. Don't jump, cause there will be sparks. If you jump across the two, the starter should engage, turning the motor over. This would diagnose a bad solenoid. About $15, at you local parts store. The other aspect not to be overlooked is a ground wire. This wire is connected to the frame and the vehicles body or motor it may have corroded or broken off.
no
Check your battery to see if it is fully charged and your wires are clean and tight. If so, you probably need a solonoid.

Yes.
Yes, but the big block may need a hi-torque starter.

The starter needs a large wire from the battery and a wire from the starter switch. These are connected to the solenoid that is attached to the starter.
Very rarely have to shim a starter. If there is excessive noise or a disengagement problem it will need to be shimmed.
