Passenger car LS swap kits simplify installing a GM LS-series engine into classic American muscle car platforms that were originally equipped with an outdated V6, Small Block or Big Block V8 engine. Whether the goal is improved reliability and modern performance, or increased horsepower, properly engineered swap components are critical for achieving correct engine positioning, driveline alignment, and long-term installation durability.
Trans-Dapt Engine Swap-In-A-Box™ Kits for passenger cars combine key installation components into complete systems designed to work together. Depending on the application, these kits include swap headers, engine mounts, oil pan, gaskets and mounting hardware and are engineered specifically for classic GM passenger car platforms.
These complete systems remove much of the guesswork from LS engine conversions by packaging the core mechanical installation components under a single part number. Builders can avoid many of the compatibility issues that occur when sourcing swap components individually.
Trans-Dapt passenger car LS swap kits are developed for some of the most popular GM muscle car platforms including Camaro, Chevelle, El Camino, Monte Carlo, Nova and other A-Body, F-Body, X-Body and G-Body vehicles. Use the filter tools below to narrow down the selection to exactly what you need.
Complete Swap Systems: Passenger car LS swap kits combine key components engineered to work together, helping simplify installation and reduce compatibility problems during the engine conversion process.

Header Finish and Material Options – Each kit is available with optional header finishes. Kits include either a set of uncoated headers, or headers coated with our high temperature ceramic-metallic finish to provide corrosion resistance and help reduce underhood temperatures. Some of our fastest selling models also offer a choice of mild steel or T304 stainless steel construction.
Application-Specific Components: Headers, engine mounts and transmission crossmembers are engineered for the vehicle chassis and engine configuration they are designed to support.
Reduces Component Guesswork: Packaging core swap components together under one part number helps builders avoid compatibility issues that can arise when sourcing parts from multiple manufacturers.

Passenger car LS swap kits are commonly used in classic GM muscle cars including Camaro, Firebird, Chevelle, El Camino, Impala, GTO, 442, Monte Carlo and other A-Body, F-Body, X-Body and G-Body based vehicles.
Most Trans-Dapt passenger car LS Swap-In-A-Box™ kits include application-specific swap headers, engine mounts, oil pan, gaskets and mounting hardware. Some kits also include a transmission crossmember designed for the transmission being installed. They are designed to physically mount the LS engine in the vehicle chassis.
Passenger car LS swap kits address the primary mechanical fitment components required to mount the engine in the chassis. Additional modifications such as wiring, fuel systems, cooling systems and drivetrain components will be required, and will depend on the specific vehicle project being performed.
Trans-Dapt passenger car LS swap kits are available through authorized dealers nationwide and internationally. Use our dealer locator to locate a distributor near you.
Important Fitment Note: Engine swap components are engineered for specific vehicle and engine combinations. Application details such as engine family, vehicle platform, cylinder head design, oil pan configuration, steering clearance, transmission type, and related components can affect installation compatibility. Always confirm the intended application before purchase, and contact the Hedman Tech Department at 562.921.0404 (Monday through Friday, 8:00 a.m. to 4:30 p.m. Pacific Time) with fitment questions.
