Break in procedures?

With any kind of hydraulic lifter, prime the oil system before the first start. With any kind of roller cam, there is no need to do any rpm at break in. Bearing clearance and temp dictates oil viscosity. You do not need to run zinc (or any other additives for that matter) with a roller. I run NAPA 10w40 in my magnum here in So Cal, similar climate I’d imagine.
