Cam bearings with Spartan Billet.

[RonA]

I'm going to have cam bearings installed in the new block and put my only slightly used Spartan billet in. Should I just drop down to about 1/2 the zinc level, or keep it at 1/2 bottle per change(every 1500 miles).

I'll be running Don's Spartan Cam set too....Good question...

One of thing you probaby already know:

Keep the tappets in order so they go back on the same cam lobe.

ZDDP levels are crazy high in our additive so 1/3 bottle is plenty for a bare block and the Spartan after break-in. Which you already did.

With cam bearings you can use 1/4 bottle. Giving you four changes per bottle of additive.
