The SBC Mech Roller Lifter Set +.300 O/C from MOREL LIFTERS is a precision upgrade designed for small-block Chevrolet builders looking to enhance their engine's valvetrain reliability and performance. This complete lifter set is tailored for engines utilizing mechanical roller cam profiles, offering improved durability over traditional flat-tappet designs.
The +.300 O/C (over-center) specification indicates a 0.300-inch offset from the lobe centerline, which helps optimize lifter geometry for specific cam profiles. This design reduces friction and wear, allowing for more aggressive cam profiles while maintaining stable valve timing and lift characteristics essential for high-rpm operation and forced induction applications.
This complete lifter set is suitable for small-block Chevrolet engines, including 283, 305, 327, 350, and 400-cubic-inch variants that require a full set of eight lifters. Proper installation requires careful calculation of pushrod length to ensure optimal performance.
