setting up ignition timing

I have a MSD 6-AL I ran on a chevy how big of a deal is it to wire it into what I have?
My first Mopar, Learning.
I will feel alot better about it once I can get the motor out this winter and see what I have.
I Know it has way to big of a cam in it now for what I want.
Plan on street driving with the occasional bracket street class racing.
Pretty high stall converter,not sure what it is.
its a 74' 360 special high performance block with small valve heads,that much I know.
not really happy with the carb. and intake set up. 318 streetmaster,and a 4160 600 vacuum secondary.
Tried running a 570 street avenger 4150 I had did not work.
with the cam in it there is very low manifold vacuum, and slow warm up.
would like to get to run a little better so I can enjoy it the rest of the summer. It loves WOT,decent power.
swapped in Champion plugs that helped.
Fun car glad I bought it.
