Your trusted source for LS swap packages, classic muscle cars, and performance engines. Built on honesty, driven by a passion for American iron.
EngineSwap Autos started in 2010 with a simple idea: give builders, collectors, and enthusiasts access to quality engines and classic cars at honest prices. What began as a small operation in San Antonio has grown into one of the most trusted names in LS swaps and classic car sales in the country.
Over 15 years, we have helped thousands of customers find the right engine for their build, the right classic for their garage, or the right complete swap package to make their project a reality. Every unit we sell is compression tested and backed by our 1-year unlimited mileage warranty.
Our connections with salvage yards, GM dealers, and private collections across North America allow us to source low-mileage truck LS pullouts, rare muscle cars, and complete swap packages that you simply will not find anywhere else at these prices.
The principles behind every engine we sell and every car we list
No inflated asking prices, no hidden fees. We price every item at fair market value so buyers can act with confidence and sellers get results.
Our team has decades of hands-on experience with LS swaps, classic builds, and performance engines. We know what we sell inside and out.
We cater to builders, restorers, and enthusiasts. We stock what the community actually needs — not just what looks good on a showroom floor.
There are a lot of places to buy an engine or a classic car. What makes us different is the combination of low prices, verified quality, and real automotive knowledge behind every listing.
Available Monday through Saturday, 8am to 7pm EST. We typically respond within a few hours.
