• Engineered for Chrysler BB V8 engines with Indy Predator aluminum heads.
• Ensures tight lifter bore engagement, improving valvetrain stability and lifter tracking under extreme load and RPM.
• Built for maximum horsepower applications, including drag racing, endurance events, and serious street/strip builds.
• 2.03" Pushrod Seat Height – Optimized for Indy Predator Geometry
• Designed with a 2.03" pushrod seat for correct alignment in Indy Predator head configurations.
• Maintains proper pushrod length and angle, ensuring optimal rocker arm geometry and valve timing accuracy.
• Prevents valvetrain stress and excessive wear in high-lift, high-RPM applications.
• Intake Offset .210" Left
• Features a .210" intake offset on the left bank, ideal for raised port head designs and large intake runners.
• Improves pushrod-to-rocker arm alignment, reducing side loading and friction.
• Enables better valve control and motion, especially in aggressive intake layouts.
• Pushrod Oiling System – Reliable Upper Valvetrain Lubrication
• Designed to deliver pressurized oil through the pushrod to rocker arms and valve tips.
• Ensures consistent lubrication in high-RPM conditions and with aftermarket rocker assemblies.
• Critical for long-term durability and reduced friction in the upper valvetrain.
• Bronze Bushing – Durable and Race-Ready
• Equipped with a solid bronze bushing for exceptional oil retention, heat dissipation, and long-term reliability.
• Withstands extreme spring pressures and camshaft loads with minimal wear.
• Eliminates the risk of needle bearing failure, making it perfect for aggressive racing environments.
• 0.300" Tall Body Design – Reinforced Strength & Stability
• Offers increased lifter-to-bore contact, improving tracking and minimizing lifter walk or deflection.
• Supports precise camshaft engagement even under extreme conditions.
• CNC-Machined Billet Steel Construction
• Machined from premium billet steel for maximum strength, heat resistance, and reliability.
• Precision tolerances ensure smooth travel and consistent lifter function across the RPM range.
• Engineered to endure high-load and high-heat environments without failure.
• Ideal for High-Lift Camshafts
• Designed for fast-ramp, high-lift cam profiles, reducing wear while supporting smooth, stable lifter movement.
• Enhances overall valvetrain performance and camshaft longevity.
• Race-Tested Performance
• Proven in elite-level Big Block (BB) race builds, including drag racing and high-output endurance platforms.
• Built to handle high-RPM stress, heat cycles, and repeated mechanical shock.
• Optimized Oil Flow & Component Longevity
• Improves oil distribution and pressure stability, reducing internal friction and extending component life.
• Helps prevent valvetrain failures by maintaining cool, lubricated operating conditions.

Applications:

• Compatible with Chrysler Big Block (BB) V8 engines using Indy Predator aluminum heads.
• Designed for configurations with 2.03" pushrod seat height, .210" intake offset (left bank), and pushrod oiling systems.
• Perfect for high-lift cams, aggressive valve-train setups, and professional race engine builds.
