If you,ve got new heads..it's good insurance to put NEW springs and keepers on now. Almost lost my engine last year when an exhaust spring broke. I was lucky it didn't drop down.

It is Zinc. I have a solid cam from Bullet in my L78 and they sugested I use Brad Penn oil in my motor because it has the Zinc still in it. Its a Green oil same as the old Kendall oils. Here is the link

Or, you could stop by your GM dealer and get some GM EOS...

I would advise *against* the Comp L78 blueprint cam...the Crane/GM unit is the one you want...trust me, all of us in Pure Stock have been there, done that....

Ditto that! I'm living proof

Rob &amp; Marlin why is the Crane Cam better than the Competition L78 Grind?? Have you guys had negative experiences with Comp. Cams??

I have not had a Comp Cam go bad on me, but simply like the Crane better because they are blueprint versions of the originals.

I know about a half dozen guys in Pure Stock that tried the Comp blueprint cam but switched to a Crane and the car picked up...and I believe one guy lost some lobes on a Comp piece? I swtiched over from a Melling blueprint cam that ended up going south...that Crane/GM cam will make power, trust me.
