The Partee Racing high-output BMW S62 longblock is built for enthusiasts who want the legendary character of the S62B50 engine with serious naturally aspirated power, improved durability, and track-capable performance. Designed for BMW E39 M5 and BMW Z8 S62 applications, this package starts with the same proven foundation as our Better Than Stock S62, then adds competition cylinder heads, dBilas 272° billet camshafts, and a purpose-built valvetrain package engineered for high-rpm reliability.
This is not a basic S62 engine rebuild. It is a complete performance-focused S62 long block for owners searching for a properly built BMW S62 engine for sale. One that keeps the soul of the factory Motorsport V8 while unlocking the airflow, camshaft profile, and supporting hardware needed for real naturally aspirated power.
Every high-output Partee Racing S62 longblock begins with our proven shortblock assembly, the same bulletproof foundation used in our Better Than Stock S62 program. From there, we add our competition cylinder head package, which is CNC ported, hand-finished, and clearanced for larger cam lobes.
That clearancing step matters. On the BMW S62, proper cylinder head clearance is required for any serious camshaft upgrade. We do the machine work correctly so the engine can take full advantage of the dBilas 272° billet cams without sacrificing reliability.
The cylinder heads are CNC ported for improved airflow, then finished and lightly polished by hand. Valves are reconditioned and back cut to improve flow and sealing, while the rest of the valvetrain is upgraded with Partee Racing custom components.
This S62 performance longblock includes:
If the valve guides are out of specification, we replace them with motorsport-quality custom guides made from Moldstar 90 for an additional charge.
When paired with Partee Racing carbon fiber velocity stacks, quality headers, a high-flowing exhaust system with catalytic converters, and the matching Partee Racing tune, this high-output BMW S62 engine package is capable of approximately 435–460 wheel horsepower.
Yes, wheel horsepower. Uncorrected on a dynojet.
Final output depends on supporting modifications, exhaust configuration, fuel quality, tuning, dyno type, and vehicle condition, but this package is designed for the S62 owner who wants real naturally aspirated performance without turning the car into an unreliable science project.
Whether you are refreshing a tired E39 M5 engine, building a street-and-track S62, replacing a failed BMW S62B50, or searching for the best built S62 longblock available, this package is designed to deliver the power, throttle response, and reliability the platform deserves.
The factory S62 is already one of BMW M’s most iconic engines. Our high-output longblock keeps the naturally aspirated V8 character intact while adding the cylinder head flow, camshaft profile, valvetrain stability, and assembly quality needed for a stronger, sharper, more capable S62.
