Cams don't get that big...

The cam in that 445W that made 660 hp @ 7000 allows the customer to idle around his neighborhood, over speedbumps, etc.

And yes, you are correct, once the carb is tuned, you should be good to go.

The good thing about the larger big blocks is that you have the horsepower and the streetability both. They will cruise, run on pump gas, etc., and you can give them as much throttle as you see fit. Pretty easy to get 700 hp out of them and cruise around like it's nothing.
