Edelbrock 1405 carb way to lean

Thanks,
I think it is stock. Was on the car when I bought it. Still has the stock rods so I assume so. Auto-light 63 plugs (I think). I have no idea what the initial timing is, I set total at 35. Every thing else is fine. I know it is lean. It was border line with the almost stock 318. Now with this engine it is just not enough. I have plaid with these for years, well years ago. But I am thinking about switching out to this tricked out Street Avenger. Looks pretty nice. Might work a little better on this engine.
