This 434ci LS is being built around one goal: making big, reliable boost power with a centrifugal supercharger.
Starting with a BPE 6 bolt block, forged rotating assembly, X-beam rods, custom camshaft designed specifically for the intended operating range, and a set of CNC-ported Brodix BR7 cylinder heads, every component has been selected to work together as a complete package rather than a collection of parts.
A centrifugal blower has very different airflow demands than a positive displacement supercharger or naturally aspirated combination. Camshaft events, compression ratio, cylinder head selection, and overall engine package must all be tailored to maximize efficiency under boost.
This build is being designed to deliver:
Excellent high-rpm airflow
Stable valvetrain operation
Strong boost efficiency
Broad usable powerband
Reliability under sustained load
The goal isn’t just horsepower, it’s creating an engine package that makes power efficiently and survives doing it.
Stay tuned as this 434ci boosted LS comes together.
