It was an Elgin cam, lifter, spring kit. 15 minutes of run time.
I'm pretty sure he used Amsoil oil. His nephew is an Amsoil dealer so he gets it from him. Not sure what weight. He also added a bottle of zinc additive.
130 psi seat pressure at 1.88" installed height.
Crane Energizer roller rockers. The cheaper cast aluminum silver rockers.



I'm seeing a couple of red flags:
1) Elgin cam and lifters = CHEAP
2) Amsoil with a bottle of zinc additive - if he is using the Amsoil Break In oil, adding zinc additive is a NO. If using Amsoil regular oil, use the Break In oil.
3) Cheap rockers - possible valvetrain bind, was everything checked?
4) 130 psi seat pressure - with that seat pressure, I'm willing to bet open pressure was 330+, another NO.

And guys wonder why flat tappet cams fail...
