Lunati Voodoo Aluminum Roller Rockers are an easily installed, bolt-on power adder for Ford V8 engines. Their needle bearing trunnion assembly greatly reduces operating friction and side-to-side oscillation, thereby increasing horsepower, torque and throttle response, as well as engine operating efficiency. Even more power can be realized with the available higher rocker ratios, which increase gross valve lift, torque and horsepower.
Rocker bodies are CNC machined from aircraft-quality, heat treated, extruded billet aluminum, for maximum strength, durability and minimum deflection. Voodoo Rockers are fitted with a precision ground roller tip and axle to reduce valve guide and valve stem tip wear. All steel components are precision machined and heat treated for increased strength and wear resistance. Each set comes ready to install with positive locking nuts that hold valve lash adjustments. They are engineered for extreme valve spring pressures and higher lift cams and are warranty protected for up to 100,000 miles. Voodoo Rockers are also clearance machined for large diameter valve springs.
Lunati Voodoo Aluminum Roller Rockers are made in the USA and are engineered for serious street/strip performance. Ford applications include: Small Block 221-302; 5.0 HO-351W; 351C- Boss 351-400M; and Big Block 429-460 engines.
