Stock Camshafts.
This page contains information regarding Nissan L-Series Camshafts.
Most of the camshafts installed in the Nissan L-Series motors are cross compatible; they are all physically the same dimensions (bearing surfaces), but the core type differs. You need to have a camshaft with the same core type as the cam towers your head has.
The table below lists the most common of the L-Series cams and their specs. Please note that the following table does not contain a complete catalog.
L6 Camshafts
This list is not exhaustive. Engines like the LD28 and L20A haven't been included due to their scarcity or general obscurity; plus chances are the oddball cams are gonna be shit anyways lol.
