BAM Roller Lifters .8430" Oversize – Pontiac / Oldsmobile, On Center Configuration (O/C), Bronze Bushing

Key Features:

• .8430" Oversize Diameter – Enhanced Fit for Worn or Custom Lifter Bores
• Designed for Pontiac and Oldsmobile V8 engines requiring an oversized lifter (.8430") due to lifter bore wear or intentional machining.
• Ensures precise lifter-to-bore contact, improving stability and reducing lifter walk.
• Offers a solution for reconditioned or sleeved blocks that need oversized lifters.
• Configuration (O/C) – Improved Pushrod Alignment
• On Center lifter body enhances pushrod clearance and valvetrain geometry, especially when using aftermarket heads or raised intake/exhaust ports.
• Ideal for high-performance builds where custom port alignment is used.
• Bronze Bushing – High-RPM Durability & Serviceability
• Fitted with solid bronze bushings for superior oil retention, heat dissipation, and wear resistance.
• Performs exceptionally well under high valve spring loads and in aggressive camshaft environments.
• Rebuildable design for extended service life, outperforming needle bearings in extreme conditions.
• Perfect for race engines, street/strip builds, and longevity-focused performance applications.
• 0.300" Tall Body – Increased Bore Engagement
• Taller lifter body provides deeper engagement within the lifter bore, improving camshaft tracking and valve timing consistency.
• Reduces lifter walk and deflection under extreme conditions, ensuring smooth valve actuation.
• Ideal for high-RPM racing, endurance builds, and high-lift camshaft setups.
• CNC-Machined Billet Steel – Precision Craftsmanship
• Constructed from premium-grade billet steel, CNC-machined to exacting tolerances.
• Heat-treated for maximum strength, durability, and long-term performance.
• Built to withstand the rigors of fast ramp camshafts, high loads, and extended duty cycles.
• Race-Proven Performance – Trusted in Pontiac & Oldsmobile Racing Builds
• Designed and tested in competitive applications, including drag, circle track, and street performance.
• Delivers stable valvetrain operation, consistent oiling, and reliable lifter action.
• The choice of engine builders looking for performance without compromise.

Applications:

• Fits Pontiac and Oldsmobile V8 engines with .8430" oversized lifter bores and offset valvetrain geometry.
• Compatible with aftermarket cylinder heads, shaft rocker systems, and high-lift camshafts.
• Ideal for race engines, re-machined blocks, and performance street applications.
