Would you even consider running a hydrolic cam?
I have a new engine build going on and considering running a hydrolic cam. Seems all the cam companies have a special oil additive with zinc etc that is supposed to help. So if I run there additive and Delo oil with zinc etc do you think it will last?

There are still a number of hyd flat tappet cams running out there. I've never had a problem with wiping out cam lobes however you here more and more about it the lack of zinc in the oils. I guess you have to consider what your building and some risks your willing to take. Even roller cams fail. Let us know what your building and maybe we can help direct you. My thoughts if it was my rebuild going on is if it was a stock type rebuild with a few mods 454 or similar and didn't have the extra 650.00 to 800.00 set aside for such I would probably just use a hyd flat tappet. Good roller set ups as you know aren't cheap. It can lead to many other items than just the cam and roller lifters. Good timing chain cover with cam button, valve springs, etc.
Good luck and I'm sure you'll make the right choice.

valvoline racing oil. silver bottle. still has zinc additive in it.
The hydralic flats tappet cams are less likely to wipe a lobe than the solid flat tappet cams. Hydralic cams don't use much spring pressure. Run the engine at initial start up for 30 mins at 2500rpms using a good oil and you should have no problems.
Good luck with your project.
If you can get the specs on the Merc 420HP cam. That is a good one to use for that project.

Had this conversation just last week with my builder. He said that the Pennzoil race oil still has the zinc either that or I'd be OK with running Amsoil syn. which I like and run in my truck. I'll be running a hydralic roller cam in the new 540's.
