FED heads make more power efficiently because we synchronize three critical elements. We specialize in high performance cylinder porting for racing applications. - Teardown/Clean/Inspect. - FED’s high performance porting via 5-Axis CNC. - Intake/exhaust/chambers (some chambers don’t apply). - Pressure tested for leak detection.
Frankenstein heads are scrutinized to achieve the perfect induction system. Cylinder heads are the most critical engine component for maximum output. FED applies advanced design processes to achieve target outcomes at each phase of the induction system.
High performance LS3 cylinder heads, for naturally aspirated and boosted applications to 1000hp. Fits factory and aftermarket LS blocks and equipment.
GM. LS3 823 stage 1 heads feature FED's advanced porting where we optimize intake and exhaust port for rapid combustion and maximum efficiency.
Optimal cylinder head designs emerge from advanced methods which incorporate the dynamics of air and fuel, turbulence, velocity, pressure, recovery and density occurring throughout the combustion process.
Jan 25, 2024 · When Frankenstein put in the effort to develop its F-series high-performance cylinder heads, they determined an improved LS casting could deliver two things – more efficiency from reduced port turbulence and a zen-like valvetrain that stays calm in extreme conditions.
It’s a relatively small class of engine builders that discover Frankenstein Engine Dynamics® but those who do know the difference. Nearly every Frankenstein intake manifold and cylinder head has demonstrated FED’s performance through world record setting race cars.
