What is the benefit of the adjustable timing keyways on the crankshaft sprocket?

The three keyways (-4, 0, +4 degrees) allow you to fine-tune your engine's ignition timing. This adjustability is useful for optimizing performance with different camshafts or for specific engine builds.

What does the Torrington thrust bearing do?

The Torrington thrust bearing helps manage the side load on the camshaft. This is particularly beneficial in performance applications to reduce wear and ensure the camshaft stays properly positioned.

What parts are included in this timing chain kit?

The kit includes a fully machined steel crankshaft sprocket, a cast camshaft sprocket, a roller timing chain, a captive Torrington bearing, a roller thrust button, and a Manley camshaft lock.

About this part

Product Details

This is the Manley Pro Series Timing Chain Kit for Small Block Chevrolet engines made from 1979 onwards. If you're rebuilding the front end of your engine, getting the timing right is crucial for how it runs, and this kit gives you the adjustability to dial it in precisely. It's a well-built set designed to handle the demands of a performance engine build.

The kit features a steel crankshaft sprocket that's been fully machined and includes three keyways. This means you can set your timing at -4, 0, or +4 degrees, giving you flexibility to tune for different camshaft profiles or performance goals. The camshaft sprocket is also machined, and it's set up to work with the included Torrington thrust bearing. This bearing helps manage the side load on the camshaft, which is important for longevity, especially with aggressive camshafts. The roller chain itself is built with .250" diameter rollers, a common size for performance applications, ensuring smooth and reliable power transfer from the crank to the cam.

When you open the box, you'll find everything you need to get this installed, including the captive Torrington bearing, a roller thrust button to keep everything aligned, and a Manley camshaft lock to secure the cam gear. This kit is a solid option for anyone looking to precisely set their engine's timing during a rebuild.
