You can't have it both ways. A dual-purpose street-strip car cannot be optimized for either venue.

Any drag racing you might do these days will be bracket racing, where each competitor has a dial-in on his car. It doesn't matter how fast or how slow your car is, what matters is that it is consistent and that the driver can cut a good light.

You could build a nice running 327 motor with a short cam that would be fuel efficient and make good manifold vacuum for operating brakes and other accessories or you could build a motor with a big cam that would be a little faster at the strip but would be awful to drive on the street with little or no low end torque, horrible mileage and little manifold vacuum.

It's up to you, I'm just trying to give you the benefit of my 45 years of doin' this stuff.
