Designed for GM LS and Gen I Small Block/Big Block applications, these kits eliminate the guesswork of sourcing matched components separately. Always install a new timing set when replacing a camshaft. Non-VVT and Non-AFM engines only - verify your engine code before ordering. A tune is recommended after installation.
