ZZ4 cam
Have a question about the zz4 gm cam. I installed the cam in a Newly rebuilt motor. What I understand is that it is a hydronic cam but requires zero/zero lash on the rocker arms? Can someone help me confirm this? Thanks

Yes, that is correct. You should adjust it per factory specs.
What other mods do you have? I'm curious how you like it. I was torn between that cam and the LT-4 repro that I ended up with.

You will kill your cam if you don't do it right.
