Timing Chain Upgrade Kit

The very early A series motors used a single row chain to rotate and control the camshaft. With the advent of performance needs came the adoption of the double row (duplex) chain. Then again in the very late years the duplex was again abandoned in favor of a single row! For those of you with any of the single row chains this easy to install kit provides all the parts needed to upgrade to the duplex chain for both performance and dependability.
