I've never lost a cam lobe. I've usually bought MP cams. I have a crane now in one of my dusters. I'll be breaking in a summit in my 318.
MrJLR, use your cam break-in oil provided, and then use Lucas engine break-in oil additive with the motor oil of your choice, I prefer 10w-30 for weight. After your 20 minutes session, use either a additive (like ZZDP Maxx), or an oil like VR-1 Valvoline for example. You'll be just fine.
