Default horsepower question

Me and my friend got into an argument the other day about how fast my car is. I say its a little under 300hp/330tq but he says its more like 250hp/270tq. I am in need of a third opinion on this...please don't flame me for asking horsepower questions, im just curious.
This is a list of everythign I have done.
94 Z28
80 series flowmaster catback exhaust (don't laugh im broke), cutout, high flow cat, moroso cold air intake, vortech aluminum inlet elbow, throttle body bypass, 160* thermostat.

thanks!

Are you guys arguing about RWHP or flywheel horsepower? If it's the latter I'd say you're right, and you probably making a little under 300hp at the flywheel (stock is 275hp)

Depends totally on the car.. I've seen LT1s dyno anywhere from 240rwhp to 270rwhp stock. Horsepower isn't worth as much as a trap speed since dynos can be stingy, get to your local track and run her.

bingo. I ran 256 stock and overheating but I have 10 up on you from the factory. Since you started at 275, i'll give you about another 25 from your mods to get you 300 FW so about 275 -280 rear wheel HP maybe
