Chevrolet Performance 3.8L 231 C.I.D. Long Block Crate Engines 89017861

This new Chevrolet Performance 3.8L crate engine (part 89017861) is a 231 cubic inch V6 long block cast in iron for both block and cylinder heads, internally balanced, aimed at restorations and factory-spec replacements for GM vehicles that originally carried this engine family. What a long block in this family covers The oil pan, valve covers, and timing cover arrive fitted, along with the water pump and harmonic balancer, giving you a complete short-to-long-block foundation. Left for the builder to add are induction and ignition entirely: no intake, carburetor, distributor, or wiring is bundled in, which is why this V6 can be finished as either a carbureted or fuel-injected setup depending on what you choose. Choosing your induction Because the long block ships without any induction system, the carbureted-versus-EFI decision is entirely yours to make based on the intake manifold and ignition components you select; just confirm your transmission, motor mounts, and wiring match this V6 platform before you start the build, since details vary across the years this engine was produced. Common questions Will this work in a classic Chevy or Pontiac build? It is a common fit for that kind of restoration, since this 3.8L V6 saw service across several GM platforms, but match the mounts and drivetrain to your specific car before ordering. Is it emissions-certified? No, so check local regulations before installing it on a street-driven vehicle. What should I check before I order? Confirm your transmission bolt pattern, motor mount style, and intended fuel system against this V6 platform, since those details shifted across the years this engine was produced.
