• Precision-machined for Chrysler BB engines (383, 400, 426, 440 CID) using Indy aluminum blocks.
• Offers a perfect fit in standard-size lifter bores, ensuring superior stability and bore engagement.
• Ideal for high-performance builds, racing engines, and serious street-strip applications.
• 1.89" Pushrod Seat Height
• Tailored for setups requiring a lower pushrod seat height to match specific rocker arm and pushrod combinations.
• Maintains proper valvetrain geometry, improving rocker-to-valve motion and reducing misalignment.
• Common in Indy head combinations and other custom Chrysler BB builds.
• Configuration - O/C
• On Center, Reduces pushrod side loading and deflection, enhancing reliability and valve train efficiency.
• Supports high-RPM precision and consistent valve motion.
• Pushrod Oiling System:
• Designed to deliver pressurized oil through the pushrods to the upper valvetrain (rockers and valve tips).
• Ensures reliable top-end lubrication, especially important in aftermarket or custom builds.
• Helps reduce friction and wear, and maintains consistent oiling under high-load, high-RPM conditions.
• 0.300" Tall Body Design:
• Increases lifter-to-bore engagement, improving strength and reducing flex under extreme loads.
• Supports smooth, consistent cam contact and enhanced valvetrain stability.
• CNC-Machined Billet Steel Construction:
• Made from premium-grade billet steel for durability and heat resistance.
• Precision machined to tight tolerances for reliable operation at high RPM and under high valve spring pressures.
• Withstands aggressive camshaft profiles and harsh engine environments.
• High-Lift Camshaft Compatibility:
• Ideal for use with fast-ramp and high-lift cams, ensuring smooth lifter tracking and reduced wear.
• Helps maintain accurate valve timing and lift in performance applications.
• Race-Tested Strength and Reliability:
• Trusted in drag racing, endurance events, and high-horsepower Chrysler BB builds.
• Proven to handle extreme RPM, temperature, and load cycles with consistent performance.
• Optimized Oil Control and Pressure Retention:
• Designed for efficient oil flow and retention, reducing friction and extending component life.
• Helps maintain stable oil pressure and improved engine efficiency under load.

Applications:

• Fits Chrysler Big Block V8 engines (383, 400, 426, 440 CID) using Indy aluminum blocks and heads.
• Designed for setups with 1.89" pushrod seat height, offset lifter configuration, and pushrod oiling systems.
