I would think a good starting point for initial would be around 16*, of course you will probably have to limit your mechanical.

I run a very similar set-up. Same carb,same cam.
What I would suggest is to set the total timming between 34-36 deg. (No vac adv).
Then check your initial,to see where it's at. Take it for a drive,and see how it runs.
This isn't a radical cam,so high initial timming won't be necessary.
You will find that your setup will run well between 12-16 initial 34-36 full advance.
This is right around where I run mine.
If you feel the need for more initial,then some recurving will be necessary.
I run the Mopar Performance distributor/elec ignition kit,and the dist works great right out of the box.

Im running 20 initial 37 total holley 770 street avenger and I dont think you can get it any better. Also I had to limit my dist last week I tried a little J B weld and it worked great, I have small dremmel tools for grinding out but this was much easier than welding in.

I'm running the XS274 and I'm got mine set to run 16 initial and 36 total. This thing runs great.
