Jason, if you already have the manifold, just get a Q-jet for it. they are a perfectly fine carb. Personally, I'm leery of running a square-bore on a spread-bore manifold, having to use an adapter. you can start a small war here on the subject of carburetors
I have the summit 1103 cam and lifter kit in my truck and it's fine. If you're going to invest more, I'd go to a newer style grind as suggested (I think I'll do a Lunati Voodoo, if I don't go ahead and build a roller-cam block).
remember, everybody's definition of daily-driver and street is different. if you want something that REALLY sounds like it has a cam, you'll be losing drivability.
