A complete beehive valve spring and cam swap kit engineered for cathedral-port LS heads, packed with PAC single beehive springs and hardened chromoly pushrods for reliable high-RPM performance. Multiple cam and pushrod length options let you tailor valve timing and valve train geometry for street or race builds and typical gains of 30–65 rear-wheel horsepower from a cam swap alone. Optional components (timing chain, oil pump, front cover gasket kit, crank bolt, retainers, compressor tool, HP Tuners MPVI4) let you buy only what you need. Competition-use item — not legal for road use in some jurisdictions.
