The '99 V8 SHO gets 235 hp and 230 lb-ft. of torque. That's stock.
My dad got a '99 SHO about a year ago, and he loves it (so do I
) It's fast, and trust me if you're gonna be racing your friend you want the SHO. Red-lining it, it dosn't shift into 2nd until you're going 50mph, and it get's there pretty fast, too!
Intake Design and Imporvement
This is an older website, but it's got a lot of good information about the SHOs. They say that dyno testing it gave them a 12-23 hp increase w/o an air filter, compared to w/ the stock filter. So if you get a high flow air filter, you could be looking at a good 8-10 hp increase, which would put you pretty close to your 250 hp goal.
btw, my dad bought his from a used car dealer for about 3,500. Not that much. It's in good shape, and runs great. It's had the tranny replaced, the cams re-welded, and we're getting readdy to have the brakes redone. not unusual for a used, 7-year old car, but well worth it.
