We show you the step-by-step process on how to convert early LS engines to a front-mount LS2 cam sensor.

Always make sure the LS1 you are buying has the Cam sensor, located on the block directly above the flywheel, the manifold absolute pressure (MAP) sensor on the intake and the aforementioned knock ...

Also, for the most part, 24x engines will have a camshaft sensor just behind the intake manifold while 58x engines typically have the cam sensor in the front timing cover.

The original Gen III car and truck LS engines placed the cam sensor at the back of the block reading the 1x trigger located on the camshaft that was compatible with the stock 24x crank reluctor.
