Engine Swaps and Dropout – Tested Used LS, HEMI, Diesel & More
Engine Swaps & Dropout Motors
Searching for a reliable used motor or a complete engine dropout for your next swap? Best Auto Car Parts Store specializes in drop out motors and complete engine & transmission liftouts pulled from clean donor vehicles. From LS1 engines and LS2 LS swap dropouts to Duramax, Powerstroke, EcoDiesel, HEMI, Coyote, Toyota, Subaru, and BMW platforms, this collection is your one-stop source for tested used engines for sale.
Every used engine dropout in this collection is removed as a complete assembly—often with accessories, harness, and sometimes transmission still attached—making it ideal for swap donors and turnkey engine swap projects. Many units are video tested, compression or leakdown tested, and documented running in the vehicle before teardown, so you know exactly what you’re getting before your crate leaves our Ohio facility.
This collection includes popular platforms such as:
Used LS engines & LS1/LS2/LS3/LS6/LQ4/LQ9 dropouts
LT and modern GM V8 engine dropouts
Duramax, Powerstroke & Eco-Diesel diesel engines
Toyota Land Cruiser 3FE, 2UZFE, 5VZFE used engines
Cadillac Northstar & CT5-V LGY turbo engines
Miata, Supra GR B48, Jeep, Nissan, and more
Whether you’re rebuilding a work truck, restoring a classic, or chasing high-horsepower performance, our used motors and engine swap dropouts offer a smarter alternative to expensive crate engines. Enthusiasts, DIY builders, and professional shops trust Best auto for OEM-quality used engines, swap-ready LS1 engine packages, and hard-to-find drop out motors that are properly tested and ready to run.
