LS1 swap?

LS1 swap?
OK, no replies yet in the "engines and internal" spot so I'll try here. I'm looking for some 4th gen owners here to fill me in on some LS1 specs. Preferably only stock or mild bolt-ons here, please! So, I'm thinking of retro-fitting an LS1 into my truck (as opposed to my 383, which I may put to good use as a super-street motor) because of the EFI and power. NOW, I'm wanting to know... Have any of you guys ever had a dyno on your LS1? I want to know ACTUAL power rating, not the conservative 320 horsesGM gave it. I'm willing to change the intake and put headers on there, headers were planned on anyway. Input please?
Also, I would be getting all of it, including the tranny. My truck weighs 3300lbs, which I believe is close to a 4th gen, so how about economy guys? It's a DD truck and if I was getting more than 20mpg I would be a happy camper. Specter, Stig?
I know I'll prolly get a lot of pro-LS1 biased answers but that's what I'm looking for.

RE: LS1 swap?
there is a dyno thread in the general tech section.
my TA made 331rwhp and 310rwtq with minor boltons (lid and catback). normal is in the 290-310 range for stock depending on the dyno, and thats about 350crank hp

Ah, that's one thing I forgot to ask: I'm not big on how the computers work and everything, I'm still researching. I may be mistaken, but tearing off the cat. wouldn't screw up the function of anything, right? Sweet, I'll check the dyno page... With a little tuning, intake, and headers, I should be able to get beyond 400 horses, right?
