SB build for street strip car.

Looking for opinions on what is the best route for a SB build to get mid to low 11's in a 69 Dart. I've got a 440 I'm leaning on putting in but I want to see the SB info first to make a fair comparison and I want to keep my self open minded for either option. I'm thinking I'll make 4-5 trips to the track a year and mostly use the car on the street so I want to avoid any crazy build that will make it "un-streetable".

The number I have in my head for HP is roughly 600, and I've read a lot about 408 strokers lately but I don't know the rough costs of putting one of those together nor what it takes to get 600hp out of one.

Any info and what is the best approach, total cost etc is appreciated. If there is a preexisting thread on this I apologize and please direct me to it.
