Edelbrock Performer-Link timing chain and gear set — 7802 for small-block SBC, solid-bushing chain, adjustable cam timing

The Edelbrock 7802 Performer-Link timing chain and gear set is a solid-bushing timing system with billet machined crank gears and adjustable cam timing for street and mild-performance small-block engines.

This kit replaces worn timing components with a true-rolling solid-bushing chain and hardened gears to reduce stretch and improve long-term timing accuracy. Designed to accept either stock or performance cams, the set offers selectable cam timing positions via three keyways and is engineered for reliable service in engines up to 6,500 RPM. Note that the kit is focused on the core timing components; installation requires separately sourced thrust bearings, offset bushings, gaskets, and fasteners.

How does this timing set reduce chain stretch and maintain timing?

The Performer-Link design uses a solid bushing chain that provides a rolling bearing surface against the sprockets rather than sliding contact. That rolling action minimizes friction and the usual elongation seen in stamped-link chains, helping the engine hold more consistent valve timing over time.

• Solid-bushing chain construction for a true rolling interface with sprockets
• Reduced friction compared with conventional stamped-link chains
• Improved durability and longer service life before replacement

What materials and treatments are used for the gears?

Crank gears are CNC-machined from SAE-1144 billet steel and then induction heat-treated to increase surface hardness and wear resistance. Cam sprockets use high-strength cast iron material rated for heavy loads, providing a robust pairing that resists accelerated wear in typical street and light performance applications.

• Billet SAE-1144 crank gears for precision tooth profile
• Induction heat treatment for improved durability
• High-tensile cast iron cam sprockets for consistent engagement

Can I adjust cam timing with this set and how precise is it?

The sprocket design includes three keyway positions that let you position the cam in early, stock, or late orientations. That allows up to approximately four degrees advance or retard from the stock position so you can optimize timing for different cams or engine setups without machining the cam or block.

• Three keyways permit factory, +4° advance, or −4° retard positions
• Useful for tuning mild performance changes and cam swaps
• Keyed design ensures repeatable and accurate timing placement

Are there operating limits or installation parts to know about?

This Performer-Link set is intended for engines running up to 6,500 RPM; it is not rated for high-rpm race use. The package provides the chain and gears but does not include thrust bearings, offset bushings, gaskets, bolts, or studs, so plan to source those items when preparing for installation.

• Rated safe to 6,500 RPM for street and mild performance engines
• Thrust bearing and related hardware must be purchased separately
• Recommended for engines where durability and timing stability matter

Who is this for: The Edelbrock 7802 Performer-Link set is aimed at owners restoring or upgrading small-block engines who want a more durable, low-stretch timing solution without moving to race-level components. It's a good choice for street-driven vehicles, cruisers, and mild performance builds where accurate timing, material quality, and reliability up to 6,500 RPM are priorities. Installers should be prepared to supply the missing thrust and mounting hardware and follow proper timing procedures during assembly.
