Degreeing the cam question ??

I got a $150 "core" 1994 360 magnum.
It has a fairly new valve job and new springs, retainers, and locks. The camshaft in it sounded good on a sound clip I heard
.I thought that I was measure everything before I tore the motor down.


I borrowed a cam degree kit. No instructions.
I know lift can be measured , what about duration ??

Looking now for camshaft degreeing for dummies instructions
