383/440 Blueprint Cam

The 383/440 Blueprint Cam from MOPAR PERFORMANCE is a precision-engineered camshaft assembly designed for high-performance big-block engine builds. Built for serious enthusiasts and professional engine builders, this component delivers the valve timing optimization needed to maximize horsepower and torque across both 383 cubic-inch and 440 cubic-inch displacement platforms. Whether you're restoring a classic Mopar muscle car or constructing a street-strip powerplant, the Blueprint Cam provides the mechanical foundation for reliable, repeatable performance gains.

This camshaft features blueprint-grade precision grinding and hardened steel construction to ensure consistent lobe geometry, valve lift, and duration specifications across thousands of engine cycles. The design optimizes intake and exhaust valve timing to improve cylinder filling, scavenging efficiency, and combustion consistency—critical factors in extracting maximum performance from Mopar's legendary wedge-head architecture. Proper cam selection and installation directly impact peak power RPM, torque curve shape, and overall drivability, making this component non-negotiable in any serious engine rebuild or upgrade program.

The 383/440 Blueprint Cam is ideal for engine builders, restoration shops, and hands-on enthusiasts who demand OEM-quality core components backed by MOPAR PERFORMANCE engineering standards. Installation requires proper valve train setup, including correct pushrod length, rocker arm geometry, and lifter preload verification. Verify your specific engine block, cylinder head configuration, and intended power band before ordering to ensure optimal matching with your fuel system, ignition timing, and induction setup. Pair this camshaft with quality valve springs, pushrods, and lifters for maximum reliability and performance realization.
