In the Hot Rod issue where they build a 5.9L Magnum with an LA front case and belt drive, here's what they say:

Quote:

Magnum engines featured a serpentine-belt accessory drive, a reverse-rotation water pump, and utilized a timing-case cover with no provision for a mechanical fuel pump. The Magnum camshaft nose was also changed and will not accept a mechanical fuel-pump drive eccentric. An LA-series timing case will bolt directly to a Magnum block, allowing mounting for the fuel pump, conventional accessories, and a standard LA-engine water pump in a retrofit application. The camshaft will also need to be ordered on a core with the LA-series nose to accept the fuel-pump eccentric.




The part I am most worries about is this: "The camshaft will also need to be ordered on a core with the LA-series nose to accept the fuel-pump eccentric."

What do they mean? Can I just purchase an LA-series camshaft, or will it not be correct? Thanks.
