Oh, come on guys. He's new here and apparently he's really hated by most. Maybe even more so than the pipester.
We should rise above the crowd and be helpful...
So I say 390.
But, I also suggest spending $75-$100 to get a couple dyno pulls if you're really interested in knowing what a machine has to say about your set up.
Or, take it down the 1/4. That'll give you a better idea and it's more fun.
Good luck.
Disclaimer... Apparently, since I just had a birthday, and no one said anything, I'm getting all crazy emotional inside and weird crap like this comes out.

was just thinking a 98 vette had around 340hp at the fly wheel ?? That would be about 290 rwhp + cam\heads\intake...I added 65 rwhp to get 355 for a guess

Should be close to 400rwhp. 
I had better heads (ported DARTS) but smaller cam 224 with full bolt ons, and dyno'd 414 unlocked.
My wife's just over 390rwhp with stock heads but a good size custom cam with all bolt ons.

Years back my 98 vette 346 ci COMP 224/228 with 243 heads LS6 intake and full boltons made 386 rwhp on W2W's Mustang dyno. Dyno numbers seem to vary a lot,but a low 400 rwhp number should be possible on a DynoJet with a good combo and a very good tune...just my two cents

Is your user name Most hated on PT.net as well? I just came from the truck world too. I had a 6.0 rcsb. My car also has the 2.73's in it, it makes it feel slower than my truck as well. But, with the setup you mentioned on pg. 1, I think you should get real close to 400rwhp, I've seen many F-bodies hit 390-400 with just a big cam and bolt-ons, there's no reason you can't hit that with the added power of the head flow and compression increase from the 243's. I do know however, the IRS takes some power away, but don't know how much, that don't matter anyway, a dyno is just a tuning tool...
