SBC Aluminum Timing Cover

The Edelbrock SBC Aluminum Timing Cover (part number 4240) is a single-piece aluminum timing cover engineered for Small Block Chevy and GM V6 applications. This polished aluminum cover delivers a finished appearance while protecting critical timing chain and gear components from contamination and debris. Unlike traditional two-piece designs, the one-piece construction eliminates potential leak points and simplifies installation on high-performance and street engines.

This complete kit arrives with all necessary gaskets, hardware, seal, and timing tab included—no additional purchases required for a proper installation. The aluminum construction provides excellent thermal characteristics while the polished finish resists corrosion and maintains a professional appearance in engine bays. The precision manufacturing ensures a leak-free seal against the block, a critical consideration in both street and competitive applications where oil loss directly impacts engine longevity and performance consistency.

SBC timing cover upgrades are essential for builders transitioning from original cast-iron covers to aftermarket components, whether for weight reduction, improved aesthetics, or compatibility with non-standard configurations. The Edelbrock design fits Small Block Chevy 262, 265, 267, 283, 302, 305, 307, 327, 350, and 400 cubic inch engines, as well as compatible GM V6 platforms. Proper timing cover selection prevents oil seepage at the front of the block—a common issue with aged or warped original covers—and ensures accurate timing mark visibility for ignition timing verification during tuning and maintenance.
