Crane Cams’ Master Catalog has an extensive list of camshafts made specifically for the LS engine family. Due to the simple fact that unique applications do occur, and new cam profiles are developed, there may be certain combinations that are not found in our standard listing.
Crane Cams provides the service to custom grind camshafts for your specific needs. This provides you with the ability use the latest lobe designs, mix and match profile combinations, change lobe separation angles and
alter the amount of centerline advance to arrive at what your engine requires. This guide lists all hydraulic roller profile designs that are available for LS engines (using 55mm/2.165” diameter journals).
The lobe profiles in this guide are grouped into design families. Then the data is compiled in vertical columns with a title for each, explaining the information it contains. For additional information contact our Tech. Support Department at 866.388.5120 or [email protected].
