Exactly what oil was used?

How were the springs set up?

It wasn’t a situation where the rockers were OE style, and the slot was contacting the stud?

I know you know how to break in a cam…….. just looking for a few more details.


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.

2200-5400. Very strong mid-range, choppy idle.

It ran for about 15 minutes until it started getting hot. He shut it down and let it cool off, then it didn't want to turn over. Cranked real slow. He pulled the plugs out and it turned over better...next he pulled a valve cover and found some rockers turned sideways. Obviously saw the glitter in the oil at that point. Then he proceeded to get violently ill. puke
