I would say you need to find a shop to build this for you. I havent seen any lt1's here in the last few years making any thing close to 1500 hp, probably for good reason. I'm sure those vettes are LSX based so the heads are miles above any lt1 unit.

Even with a rollcage 1500hp gets a little dicey in the Imp chassis. Once I thought about it more I know another guy with a car that likely makes maybe 1300 or so, full weight, lots of stock parts on the car. Converted Donovan 434 to accept all the LT1 specific stuff and a blower for the boost, boost is fairly low maybe about 15psi with a small shot of nitous to cool it. Car makes enough power to trap mid to high 140s, between breakage and traction issues he is only getting mid 9s out of it though, and he did a minitub on it to get more rubber under there. It is still stock style suspension.
Maybe the craziest thing about the whole thing is he is using the OEM engine/tranny management, the 4L60E and 8.5" 10bolt have to round out the top three craziest things he has kept. It is street driven and dragged, don't think it will road race though, the suspension work needed to get this kind of power to hook in a straight line usually wont corner well. For example they use an antiroll system that keeps the axle and chassis dead parallel, at low speed cornering it feels good but try and push it and the rear will suddenly break away because it is like having way too stiff a rear swaybar, bet if you had stickey enough tires you would actually lift the inside rear tire in a hard corner. For fast cornering you need some articulation.
There is a car in Sweden that comes close to what you are looking for too, this one a blower actual LT1 block, runs high 9s, lots more work in the rear suspension, like Fab9" and 4 link, BIG boost numbers high 20s-30, he actually does all you want to some degree. Appears to me DEEP pockets built that car, aftermarket management, 4L80E with seperate controller. Running the weight and mph numbers this may be about 1000hp, nowhere near the 1500 pipedream you have.

quickss is a good friend of his and could add more about the car.
I don't think you have any gasp of what this sort of thing takes, both of these guys are a bit older, wiser and more experianced.

im almost 30 and been around this stuff since i can remember..i know i dont have the knowledge of a lot of guys, but im a sponge and a fast learner and will a little help and guidence i could do this myself. that being said, i will definetly have some shops who specialize in each area help me out with things i feel are over my head. this build will take atleast a year to complete. i will not rush it or cut corners, i want it done right the first time. i will use parts that WONT break and parts that will be riliable. I resgisterd over at impalassforum a couple years ago and saw a few guys that road race them, and i feel that if i can find a shop that knows what there doing can setup the suspension very well. This wont be my first B-body i know there a little twitchy, but i think theres enough technology out there to make it comfortable

I have an idea for you, go to the chevy dealership and get a SS full size truck. Get yourself a nice trailer, then go buy a dedicated racecar. You will still have money left and you will be better able to enjoy them for what they are.
Honestly, that kind of hp will twist a factory impy in half and just about any other factory car for that manner. If you have the coin like you say your coming into build the body style you like and let your chassis guy figure it all out. A project like this is going to take considerable time (read about 1 year) if you want it done right.
A good friend of mine won the lottery (24 mil.) and he started projects like the one your describing except using corvettes, he finished 2 of the vettes (each with over 1100 hp) and honestly they are not "all that" and they are very underperforming for the amount of hp on tap. He has a new z06 vette and he loves it compared to his project cars, its much cheaper to insure (try insuring a 1100 hp vette at replacement cost), he can drive it anywhere and not worry about if it breaks who will fix it. For example the brakes on his vettes are the same Brembo brakes used on the Ferrari F40, to get a "basic brake job" done is $4000.00!!!! and that with him doing the labor.
Building high end cars need/get high end maintenance just remember that when starting a serious project, It takes big money to build them, drive them, and work on them.

Im sure the chassis shop i find to do this for me can add a cross member or 2 and with a 12pt cage it will be plenly strong enough, maybe even a midplate or something..This is why i posted this guys. i need some assistance in getting this writtin down what i want. i want to be able to call these shops and tell them EXACTLY what i want, what will work and what wont

100K won't last any time....
I know guys that run the nmra stuff...shoot they go through 100K like play money.
Set a realistic goal...if you want an impala then do a head cam 383 or something, then add a power adder later if need be.
Also don't get too many ideas if you haven't gotten a settlement yet. b/c lawyers are going to eat up just about all of it. I been through that.

I am normally the guy not telling people this or that cant be done but this is almost impossible. I think your 100k budget is going to go out the window if you proceed with it. I would also be more realistic, maybe 1200hp goal. and i mean flywheel, so around 1000rwhp or so.
Adjust your budget or goals. The two you have right now shouldnt be in the same sentence.

Honestly, your goals of single digit Et's, out handling the best sportscars and being a great driver for 100k is unrealistic esecially if you want it nice and plan to keep it nice.
Find a good shop, develope a good relationship with them and have them build the car with your specifications: 1000 plus rwhp, single digit ET's, outhandle sportscars, and be subtle enough to be a driver. Don't waste your time talking to us hillbillies and gathering constructive critisism on the project. Build what you want and not worry about us. If you spend enough money maybe you can get in Hot Rod magazine or join the next Powerless Tour.

Could you drive this on the street? Do you think it would go around corners? And its only making 1,350 at the flywheel with a 383ci Dart Iron Eagle block.

First pass on the new motor. Eventually ran low 8's in the PROEdelbrock Xtreme Street series.

I know AI has a f-body customr out there with a over 1000rwhp 355 Lt1.
You really do need to stop planning and start learning. The LT1 is capable of a lot more than it is given credit for and sticking with the original platform would save some money and hassle. Combine that with scaling down your goals and I think you can have a monster of a car.

no disrespect intented but i know enough as of right now to start thinking about what i want to build. like i said this will take a year to do the whole car so nothing is in concrete right now. Im here to get ideas so i can start planning things..im in the "brainstorm" stage right now. As i progress through the build ill learn things along the way and things that are to much for me to handle ill have a "professional" help me along..
