It can range from High 200's to really low 300's like 315ish being max. Only way to tell is with a dyno. Some cars re factory freaks.

I have seen some that are cammed at only 330. So yeah it is possible. If your compression is dead on and you don't have any kind of blowby then you should be right around the 300 mark.

your wrong....

the LS1 z28's were rated at 305hp...when in fact...MOST of them put that down to the wheels, or even more...they were severely underrated from the factory.

Nither, a Dyno Dynamics. The guys at the shop I had it done at said I would make around 330whp on a Dynojet. They just had a shop open up with a Dynojet around my area so I'm going to see how much I put down.
