* Brand and Model: A V8 from a luxury car manufacturer like Mercedes-Benz or a high-performance brand like Ford Mustang Shelby GT500 will be significantly more expensive than a V8 from a truck manufacturer like Chevrolet.
* New vs. Used: A brand-new V8 engine will cost thousands of dollars more than a used one, with the price of the used engine depending heavily on its condition and mileage.
* Application: A V8 intended for a car will generally be cheaper than one designed for a marine application (boats) or heavy-duty applications like trucks or industrial machinery.
* Where you buy it: Prices vary depending on whether you buy from a dealership, a salvage yard, an engine rebuilder, or online marketplaces.
Therefore, it's impossible to give a single price. You could find used V8 engines for a few hundred dollars (potentially requiring significant refurbishment), or you could easily spend tens of thousands of dollars on a new, high-performance V8. To get a price, you need to specify the make, model, year, condition, and intended use of the engine.
