Something you won’t see very often on a crate motor is the starter.  It’s another of those accessory pieces you’ll absolutely need, but it’s often not included in the basic price. The same applies to a water pump along with the associated pulleys.  Ditto with plug wires, wire sleeves, wire dividers, water necks, fuel lines and so on.  All of these little things add up when it comes to the final tab on your crate motor. Keep them in mind.
