Question about cam degreeing

Hey.
I'm doing a LS swap into my 71 el camino.
The engine is from an chevrolet express 2003 5.3L.
engine is taken apart and I'm going to rebuild it now, the cam i have decided to buy is Grind Number:HR-224/347-2S1-15 4A
I have read that you have to degree the cam before puttin the chain on, but i don't have the tool for it.
There is a mark on the cam wheel so i'm wondering if it is possible to use this one ore do i need to buy a special tool to get the job done right?
the timing chain is LS2 BILLET TIMING SET

I'm sorry if this is a bit messy, It's my first post

You really should degree the cam. It's an iterative procedure: install, measure, adjust, re-measure, re-adjust, re-measure, repeat until done. It is not hard it is only time consuming, and requires the tools.

Here is why you should measure:

My first timing set was way off, my second set was nearly spot on. Why? No idea, but that is why checking is worth the effort.
