From San Antonio to Nationwide
EngineSwap Autos started in 2010 with a simple idea: give builders, collectors, and enthusiasts access to quality engines 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 crate engine sales in the country.
Over 15 years, we have helped thousands of customers find the right engine for their build, the right transmission to back it, 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 performance shops across North America allow us to source low-mileage LS pullouts, new crate engines, and complete swap packages that you simply will not find anywhere else at these prices.
What We Stand For
The principles behind every engine and transmission we list
Honest Pricing
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.
Technical Expertise
Our team has decades of hands-on experience with LS swaps, engine builds, and drivetrain matching. We know what we sell inside and out.
Builder First
We cater to builders, restorers, and enthusiasts. We stock what the community actually needs — not just what looks good on a showroom floor.
