Cadillac 425-500 Hyd. Cam 252H

The Cadillac 425-500 Hyd. Cam 252H from COMP CAMS is a high-energy hydraulic flat tappet camshaft engineered for Cadillac V8 engines seeking reliable mid-range performance and street-friendly operation. This camshaft is designed for builders and enthusiasts who prioritize consistent valve actuation without the complexity of solid lifter systems. The hydraulic flat tappet design automatically adjusts for thermal expansion, eliminating the need for manual valve lash adjustments and making it ideal for daily-driven or moderately modified V8 platforms.

This Cadillac 425-500 Hyd. Cam 252H delivers 0.465 inches of lift on both intake and exhaust, with a 252-degree duration specification and 110-degree lobe separation angle (LSA) that optimizes power delivery between 800 and 4800 RPM. The symmetric lift and duration values ensure balanced cylinder breathing and stable idle characteristics at lower engine speeds. COMP CAMS manufactures this camshaft to exacting tolerances, ensuring precise valve timing and minimal lobe wear over extended service life. The hydraulic lifter system accommodates typical orifice sizing and spring pressures found in stock and lightly modified Cadillac big-block engines, reducing NVH (noise, vibration, harshness) compared to mechanical alternatives.

Builders restoring or upgrading Cadillac 425 and 500 cubic-inch V8 engines will find the Cadillac 425-500 Hyd. Cam 252H well-suited for street performance, towing, and cruise applications where low-end torque and driveability are priorities. Installation requires standard camshaft timing tools and baseline valve lash procedures typical of hydraulic lifter systems. Verify compatibility with your existing intake manifold, cylinder head ports, and lifter bore condition before installation. This camshaft pairs effectively with stock or mildly ported heads and standard fuel systems for a balanced upgrade path.
