SBC Nostalgia Hyd. Cam N+L79H

The COMP Cams SBC Nostalgia Hydraulic Cam (Part #12-671-4) is a purpose-built hydraulic flat-tappet camshaft engineered for small block Chevy engines in classic muscle car and nostalgia drag racing applications. This hydraulic cam delivers the mechanical simplicity and proven reliability of a flat-tappet design while maintaining the maintenance advantages of hydraulic valve lifters, making it an ideal choice for builders focused on authentic vintage performance without constant valve adjustment.

The Nostalgia Plus profile features 0.468-inch intake lift and 0.462-inch exhaust lift, paired with 276-degree intake and 283-degree exhaust duration at 0.050-inch valve opening. The 112-degree lobe separation angle (LSA) creates a broad torque band optimized for street and bracket racing, while the 1800–6200 RPM operating range keeps power delivery within the scope of vintage-era engine management and carburetor tuning. The hydraulic design automatically compensates for thermal expansion and valve train wear, eliminating the need for frequent lash adjustments—a significant advantage in high-heat race environments where mechanical adjusters demand constant attention.

This camshaft suits small block Chevy builders pursuing authentic nostalgia competition, whether in NHRA bracket racing, vintage hot rod events, or street performance builds where OEM-style hydraulic lifter technology remains the preference. The moderate lift and duration specifications work efficiently with stock and mildly ported cylinder heads, avoiding the need for expensive valvetrain upgrades while delivering repeatable, predictable power. COMP Cams' Nostalgia Plus line maintains factory-correct operation characteristics, making this an excellent fit for competitors and enthusiasts unwilling to sacrifice reliability for performance.
