Small Block Chevy engine swap kits simplify installing a Chevrolet Small Block V8 engine into classic cars, trucks and off-road vehicles that were originally equipped with smaller engines or different powertrain configurations. Whether the goal is increased horsepower, improved performance, or converting a vehicle to V8 power, 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 Small Block Chevy conversions 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 the vehicle platform they are designed to support.
These complete systems remove much of the guesswork from engine conversion projects 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 Small Block Chevy engine swap kits are developed for popular conversion platforms including Jeep CJ5, CJ6 and CJ7 V8 swaps, and Chevy/GMC S10 Blazer and S15 Jimmy V8 conversion projects. These applications allow builders to install a classic Gen I or Gen II 283-400 Chevrolet Small Block V8 engine into lightweight platforms where additional power and performance are desired.

Complete Swap Systems: Small Block Chevy engine swap kits combine key components engineered to work together, helping simplify installation and reduce compatibility problems during the engine conversion process.
Designed for Popular V8 Conversion Platforms: Developed for 1972-1986 Jeep CJ V8 conversions, and 1982-2004 S10 V8 swaps. Separate kits to accommodate early 1955-1978 SB engines and 1986-2000 SB Chevy engines are available.
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 for long-lasting good looks and help reduce underhood temperatures. Some of our fastest moving kits are available in mild steel or T304 stainless steel construction, or with our heavy-duty ELITE® header construction.
Application-Specific Components: Headers, engine mounts and related hardware 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.
