tune-up specs

Can someone tell me what the idle speed and timing should be for a 351(5.8) W with 2bbl carb. I can't seem to find anything in the way of factory spec's on the internet..

I'd start with 6º and work up to 10º using a vacuum gauge in conjunction with the timing light until you find the sweet spot.
Found this but's quite a write-up-

The problem with "factory specs" is that they would assume full emissions dress, which I seriously doubt you've got? I have a Haynes that covers it, but all it says is "see underhood sticker", because there were so many variations.
