Dont pay attention to what everyone in miami says, change the cam.

Read this, copy this, he is making 450hp to the crank.

They are rear wheel numbers, if you want more, pick a larger cam than the Hotcam.

Hotcam has only a slight lope, but nothing that will cause any problems.

But keep in mind that GM did a good job with the LT1 in the first place. 13.xx seconds with traps of 102-105 mph. Now this was done with 300hp. IMHO to get to 450hp there will be some negative effects to the orig. design to get there. It may be any or all of the following, idle quality, low end torque, gas milage, reliability, emissions etc.
My whole point I am trying to make is carefully decide what you want out of the car, and not just the 450 hp part, decide how you will be using the car, then make the changes. I am happy with my car, see signature below, but to be honest, if I had it all to do again, I would have considered the supercharger route, or titled it in a state that does not have emissions inspections. Also mine is not my daily driver, it sees about 2000-3000 miles a year.

People buy their corvettes for a lot of reasons, some as you can see by the posts here use them to test their mechanical ability at the strip, others for road courses, and some (like me) just to get out on the mountain back roads and kick out the jams.
A lot of thought went into building your car, 450hp is great if you plan to drag it or need to go 160+mph,but i have found that for me on the back roads that more hp just means its easier to break back the tires lose in the corners. ...joe

To do it safely with a SC or nitrous, you'd need to build a bottom end for it. The right headwork, cam, exhaust and tuning can get you there easily and you can still have pretty good mileage and driveability, too.
