LSX engine performance meets purpose-built forced induction in this Chevrolet Performance LSX376-B15 crate engine and Magnuson Heartbeat TVS2300 supercharger package. Designed for high-performance custom builds, this combination pairs the 6.2L LSX platform with a matched supercharger system for builders looking to create a serious boosted LS powertrain.
At the center of the package is the LSX376-B15 crate engine, built around a cast-iron LSX Bowtie block with 6-bolt cross-bolted main caps. The engine features a forged steel crankshaft, forged 4340 H-beam connecting rods, and forged aluminum pistons with a 9.0:1 compression ratio. This combination provides a strong foundation for forced-induction applications while retaining the familiar Gen IV LS architecture.
The 376-cubic-inch engine displaces 6.2 liters, making it a natural choice for buyers searching for a 6.2 LS crate engine or high-performance LSX powerplant. High-flow aluminum LS3-style rectangular-port cylinder heads complement the LSX short-block configuration.
Magnuson Heartbeat TVS2300 Supercharger
The Magnuson Heartbeat TVS2300 supercharger is matched to the LSX376-B15 for a complete forced-induction setup. Its twin four-lobe rotor design and integrated intercooling system are engineered to provide responsive boost and manage intake temperatures in a compact package.
The supercharger assembly includes high-flow fuel rails, matched fuel injectors, and an electronic throttle body, helping simplify the process of building a complete boosted LS engine combination.
