Im probably going to have about 10 grand to blow once I get back from Korea. Id like to go FI with my 98 but I have concerns on how much the aluminum block can handle. Id like to go with the usual boltons.. Suspension, 12 bolt, Chromoly Driveshaft, Slicks and skinnies, Weight reduction... ect ect... Id like to also do a head/cam swap before I throw a supercherger on. Whats a good head/cam combo for an FI car? How much does it cost to build the bottom end and what parts should I go with? Will the block hold the power?

There are several ways to go faster. How fast you go and which method you use depends on how much you want to spend. The cheapest is Nitrous $600+, Heads/Cam $3,600+, Blower/Cam $9,200+, Dyno Tune $450, Roll Bar/Cage $1,400, 'Built' motor $10,000-$26,000 (but the sky's the limit). These are just some rough estimates to get you thinking in the right ballparks, but can vary greatly depending on what else you do at the time and exactly what parts you opt to go with. For example you can spend $1,500 or $4,000 on heads. I have a $550 nitrous kit that I have around $1,000 tied up in so far and haven't even installed it yet. LS1 blocks are pretty tough and capable of handling a lot of hp.
If you want to go fast be prepared to dig deep or get sponsors with deep pockets. The days of getting a Keith Black 1000 horse Hemi for $5,000 are long gone.
AND THANK YOU for what you and your brothers and sisters are doing for the rest of us. We appreciate you.

Well, if you plan on keep your block stock. Adding only a Procharger will get you about 450 rwhp. And should be fairly safe. Since the pistons usually hold up to 500 rwhp.Black 1999 Blown Convertible A4

I have run in excess of 500rwhp (blower) for some time, currently 603rwhp (approx. 735hp flywheel) and have a friend who took his D-1 6-Speed C5 to 9.86 @ 142mph over two years ago which is around 800rwhp (blower and spray) approx. 900 hp flywheel. (He is currently running a C6 with over 1,000rwhp)

Opps, worded it wrong. The block can stand alot of HP, including the crank and heads.
What I meant was the pistons.

Well I hate to disagree with you....but the 97-98 LS1 blocks have thinner walls than the LS2 blocks......yea...they may make 1000hp but they will not last...that I assure you......I dont care what anyone says about that one.....when you start pushing those blocks over 500hp you are just on borrowed time......they were designed to safely handle around 500hp......anything over that and you're pushing your luck.....

time". Just exactly WHAT do you base your opinion on? You mentioned the 97-98 LS1 blocks "have thinner walls than the LS2 blocks", were we comparing the LS1-LS2? And what about the 99-04 LS1 blocks? Also WHICH specific walls were you referring to and what are the specs of those walls?

BTW, how do you know how long I think a LS1 is going to last? (YOU said " it will not last as long as you think....."). Don't tell me that besides being an expert engine builder you're a mind reader too!!
No offence meant, but I am open minded and do care what other people say (unlike you) and will take the word of published material and the experience of a large number of the best engine builders before I will listen to some "internet Genius" I've never heard of (you) and I have supplied the references, names and phone numbers to back up what I say. The only reason that I am taking the time to respond to you, is because I don't think it's doing anybody a favor to give people erroneus advice. The LS1 is a great engine and as I quoted previously from Mr. Endres' book " the blocks have proven capable of withstanding in excess of 800 horsepower". Chapter 4, page 37, paragraph 1. People new to mods are often afraid any change is going to demolish their motor (like blowers, or nitrous) and they don't need to be told their engines are weaker than they really are.

Ok....instead of arguing with you about all this I'll just say.....it's your motor....run it...build it.....do anything you want to with it.......
I've read that book......and like anything you read you have to take into consideration it's that guys opinion. I'm not saying that a LS1 can't make 800hp....I'm saying it's not going to last long if you push it to that. It's just not going to happen! When you exceed the limits of the stock crankshaft, pistons, rods, and such it's just a matter of time before something breaks! I will bet you ANY amount of money you can't show me a 800hp LS1 with stock internals and make it last for 100K miles! It's just not going to happen. I just put well over $30K into my car but I dont think it will last that long! And I have the best of everything in that motor! But I know how I drive it and I know that regardless of the quality of the parts it's just a matter of time! Have you even built a motor? This has nothing to do with being open minded. I listen to what anyone has to say but I've been around long enough to know the limits of a small block motor. I've got a treasure trove of reading materials at the house that I read to know ones opinion. But, I've also built the motors and seen what they can do. Correct me if I'm wrong but this is the Forced Induction section.....is your car even forced induction??? I've built enough turbo cars to know for myself what's good and not good. I dont claim to be an expert either. But, I'm not going to sit there and listen to someone tell another person that you can push a motor that much without telling the flip side of the story. That's just my point. The guy wanted to know how to spend $10K.....I think if I were going to put that much into something I'd want to know the pro's and cons dont you.

NOW you've gone from talking about LS1's putting out 500rwhp living on "borrowed time" to betting me on an 800 hp LS1 WITH STOCK INTERNALS lasting 100k miles? AND would you like it run at 10,000 RPM's too? AND perhaps with NO OIL? You are getting more rediculous all the time. AND YES I do have a blown LS1 like I said in my original post "I have run in excess of 500rwhp (blower) for some time, currently 603rwhp (approx. 735hp flywheel)".
BTW, YOU said "But, I'm not going to sit there and listen to someone tell another person that you can push a motor that much without telling the flip side". Could you point out to me WHERE I told the initiator of this thread how much they "can push a motor"?
