Product Details

This Edelbrock Performer-Link timing chain and gear set includes the chain and sprockets needed to set your engine's valve timing. It's designed to work with either stock camshafts or Edelbrock cams, making it a versatile choice for your Buick 400, 430, or 455 cubic inch big-block engine. This set fits a wide range of Buick vehicles from the late 1960s through the mid-1970s, including models like the Electra, LeSabre, and Riviera.

The key feature here is the solid-bushing chain. Unlike other designs, this chain has a true bearing surface that rolls with the sprockets. This design helps prevent chain stretch, which is crucial for maintaining precise valve timing and ensuring your engine runs smoothly. The cam sprockets are well-built from 35,000 psi tensile strength cast iron, while the crank sprockets are made from billet SAE-1144 steel that's been induction heat treated for durability. This set is intended for use up to 6500 RPM.

When installing, remember to avoid hammering directly on the chain or sprockets, as this can cause damage. Edelbrock recommends using a sleeve or carefully alternating blows on a brass drift punch to avoid cocking the sprockets. Always check for clearance between the chain, block, and front cover before reassembly, and ensure the cam and crank sprockets are perfectly aligned to prevent premature failure.
