LS 6.2L Throttle Body EFI – 530 HP on 91 Octane

This 6.2L LS-compatible performance engine is built for enthusiasts looking for a high-performance naturally aspirated LS engine with strong street manners and the simplicity of throttle-body injection. Built around a high-strength LSX-style cast iron block and designed for 91 octane pump gas, this 376ci combination uses performance aluminum heads, a BTR performance camshaft, and an Edelbrock Dual Plane Performer RPM LS3.

The LS TBI engine package uses a Holley Stealth 4150 throttle-body injection system, providing modern electronic fuel and ignition control while retaining the traditional appearance and simplicity of a carbureted-style intake and throttle body.

Airflow is provided by BluePrint PS8015 aluminum LS3-style cylinder heads with 259cc intake runners and 102cc exhaust runners. Combined with the high-strength 376ci rotating assembly and matched performance components, this engine delivers strong naturally aspirated performance with excellent street usability.

This is a purpose-built 376ci LS TBI crate engine, designed for enthusiasts who want modern EFI technology with the classic look, feel, and simplicity of a traditional performance engine.
