*These items were not used in this buildup nor included in the overall price but are included for reference.

**The overall cost of this engine may seem high, but it includes everything from the carburetor to the oil pan, including the starter motor, water pump, belt, and accessory drive. We didn't include the alternator and power steering pump because those pieces were included with the original engine. All these details are items the street engine will need but are rarely included in the overall price of an engine-especially crate engines.
