As for weight of your camaro, i guessing the car itself weighs more like around 3300lbs or so
If you run that 4.56 gear with a .70 OD then it ain't so bad on the street... you'll need some suspension work to hook up in first gear on a 700r4 with 4.56 gears though.

Don't be so caught up in throwing money at the engine, the rest of your drivetrain means a hell of a lot. You could probably hit 7's with all factory parts except for a mild cam and headers when it came to your engine.

There are a lot of slow 500hp cars out there because they didn't set the drivetrain up to match the engine.
