ls6 ls7?
You will also need a stout fuel-system and some serious tuning. Who is going to build the motor? I would just do an iron 370 or 408 and centri-blower/turbo it. Look at some of the higher HP set-ups in the dyno section. You will be spending about $20K for 1000chp with decent manners...

Probably not going to happen with the turbo set up. A good sound yes, but buying a cam just for that will not happen with the forced induction set up. The twin screw you had mention probably will not happen either unless you plan on cutting up your wiper cowl. The billet manifold that was mention is also uneccesary. I would run a LS1 block in a 383, or ls2 block in the 402 sizes. Talk and ask around about the set up to some of the sponsors on here. They are very helpfull. I have a buddy with a stock cubbed 2000SS 347, single turbo set up. Nothing special at all other than running a stand alone unit. It made 812 rwhp & 744rwtq. It's a daily driver and he has put about 6000 miles on it with no problems.
. You can build a stout 346 with boost. However, more cubes will always make the power with less boost/effort when properly set up. You obviously haven't kept up much on the overlap to boost discussions in the FI threads. You can run a nice, lopey cam that will still love the boost all day long as long as you properly manage your valve events. Bane was simply offering an example of the best pieces to show the guy what 'the good stuff' can cost and that no budget is big enough when it comes to building a strong, reliable engine (Fi or not).
LS67camaro, that kind of coin will definately buy you one badass street/strip machine. Make sure you think through and research every move you make so it turns out as good as it can get on the first run. APS is getting into the turbo game so you've got good timing. Call around and ask sponsors that have put out high-hp FI setups similar to what you're looking to build. Their experiance and previous mistakes will aid you in a more successful build. Remember, A LOT of people pushing upwards of 700rwhp (everyone, actually lol) are breaking things left and right so be careful and keep some of the dough around for when things do decide to give out.

Gonna need a bit more than 20k to drive a 1000 horse car away from the shop, cause it will only be a matter of miles before something is broken, the stock clutch wont handle 400 horse for very long so, you've got a few things you need to take care of.

Like has been stated, all the little things really add up. Something as simple as a fuel system can get get real expensive real quick. Look at the Nasty performance website under the f-body fuel setups and you will get what I am saying.
As far as the tranny setup, if you decide to keep the m6, things will get really pricey. If you are making ~1000 hp, you can break even the best one available. Nothing is made to stand up behind that much power for very long. I am not saying you can't do it, but breakage will happen, it is just a question of when. Honestly that goes for everything in a car like that.
Like I said, there are 1000 ways to build this much power. The more cubes you use, the more linear the power delivery "should be". Alas, the amount of money spent is parallel to the power curve. No, to be honest it is on a multiple of 1,000

Go with a built for boost ls2 402, and an 8-rib F1R or a turbo setup and you can get 800 easy. You'll still have to pay a ton for upgraded everything (fuel, driveline, etc.)

And I personally would scrap the kb idea. With 800 hp, traction would be impossible. To actually use that power and race w/ it, I'd go with a ProCharger F1R. Or of course a turbo setup with an electronic boost controller would be great b/c you could dial it up for the track, dial it down for the street. That kb, while not practical, would be fun though. There is a guy on corvetteforum by the name of american_hp with a kb 402. Something rediculous like 700ft/lb torque at 2500rpm. Buy stock in rubber!

Ok, i just wondered why 402, not high cubes. i think the warhawk lsx is a good choice because i can't justify spending 6k on a block when i could spend 2.
As for a kb setup thats the reason i like it, but even with drag radials i still couldnt get traction.
i think a built lsx with a TT setup at low boost would work very well, since i could up the boost at the track.

If it was my car I would go the twin turbo route, with an LSX block if you have the coin.. not sure about maxing it out at 454, but going with a slightly smaller bore so if the **** hits the fan you can rebuild it. maybe a 4 inch bore with a 4.125 stroke all forged of course.. topped with some AFR or TFS or ALL PRO heads professionally cleaned up, a victor jr manifold port matched with an intake elbow, and as big a throttle body as I could fit. Run about 9:1 to 9.5:1 compression and 15-16 psi on 93. (I like bumping compression for better throttle response off boost, though it requires more octane sooner when you crank the boost) As far as turbos, something along the lines of twin 67's would probably work pretty well, but it would be better to ask that in FI or advanced. I'm very interested in what you do with this I hope it turns out well!

thanks asmodeus. I'm we have the same general idea. 9.5 to 1 sounds pretty high, but im no expert. i don't want to go to big on the turbos. i want to get a semi quike spool, but not so small that i can't make big power, and i'm always in boost. the LSX block looks good but i'm not sure how much differtent it is than a normally ls1 (im not very gen III noledgeable). intake wise why not just an ls6 intake, since the kit i like is matched for that.
the ls6 intake is agood for lwoer hp apps, but when youre pushing that kinda hp youre elaving hp on the table and the intake amy not ahndle that muchb oost. id suggest either a custom made sheet emtal intake or the weiland metal ones
