Chevrolet Performance LSX 454 Long Block Crate Engines 19417357

This Chevrolet Performance LSX 454 (part 19417357) pairs big-block displacement, 7.4L or 454 cubic inches, with LS-architecture packaging, using a reinforced LSX cast-iron block and an 8-bolt crankshaft flange built for forced induction. Chevrolet Performance says the combination supports well past 600 HP naturally aspirated and can reach over 1,000 HP once boosted. A platform, not a finished engine This long block is intentionally bare in key areas: there is no wiring or electronics at all, and the intake manifold, the throttle body, an oil pan, and a water pump are all absent too, which is why Chevrolet Performance markets it as a foundation for builders adding their own fuel system, induction, and accessory drive rather than a complete turnkey package. Aftermarket coil brackets are required since none ship with it. Where it is meant to go Chevrolet Performance points this LSX 454 toward off-road rigs and street vehicles built before 1976, rather than installation in a modern emissions-controlled car, and it is explicitly not intended for marine applications. The aluminum cylinder heads and hydraulic roller camshaft are built to handle high-boost and extreme-horsepower setups once you add your own fuel and induction system. Before you order Does it include an oil pan or flywheel? No, neither is included; both must be sourced to match your application. Does coverage follow the engine anywhere? Not according to this listing: units titled and driven abroad fall outside its coverage.
