Im New and Have a Question My brother has a 96 z28 just rotting away in his garage. He currently has a procharger,i believe his converter is a 3000 or 3500 stall from precision industries a built tranny and some drag suspension stuff. He says he has no time to mess with it due to his current situation (married with a kid). Any way i was thinking about buying a built s/b , a set of ported heads. and cams to get this thing moving. I need some info on who and where to get this from?
He said he thinks his computer in the car is messed up but not for sure . Also he has lt1 edit.

Well first he should only buy 1 cam since more then 1 won't be useful. Second he needs to figure out whats wrong with it before he goes and buys parts...I can assure you heads arent the problem.

yeah, i would definitely have him figure out what is wrong with it before i would go buying parts for it. one thing that doesnt sound good is that he had a procharger on an lt1. superchargers and lt1's dont mix well. unless, of course, he already made some modifications to the block itself. as far as parts go for anything on this car, try thunderracing.com or tbyrnemotorsports.com. my personal preference.

GT your gonna need to give us more info. the engine is only availible used or rebuilt and is not a normal small block. the heads arent either. we need more info before any of us can really help. find out everything you can and we'll tell you more than youve ever wanted to know.

but anyways, no, the block in particular isnt. block was a poor choice of a word there. i shouldve said motor there. but anyways, i'm sure the stock pistons dont help lower the compression ratio to make better use of the blower. with a stock compression ratio of ~10.5:1, your not going to be able to run much boost at all without some good engine mods and run it very long. i know there are people out there who have done it. i'm sure you can run it fine at 4 or 5 psi. ive heard of plenty people doing so. i am not an expert on superchargers nor am i claiming to be. i have, however, heard a lot of bad stories about lt1's and superchargers and very rarely do i here any good ones (at least as far as stock lt1's are concerned). the original poster mentioned a procharger on the engine and didnt note that the engine was any thing other than stock. he also didnt mention the psi, it very well could have been ran at a low psi and the motor itself could be fine. i personally would want to take a good detailed look at the motor (block, heads, valvetrain, etc.) before i started working on it. if it looks good, i personally would reuse the motor and just work on building it up from there. you can get the bottom end rebuilt if it needs it. send the heads off to get ported, etc. he also needs to sit down and write up a plan as far as what he wants this engine to do and what parts he needs to get it there before he starts throwing miscellaneous parts together. i, personally, would like to keep the blower and design my engine to work around it (actually, i'd rather a turbo).

ok the engine is stock , yes the car runs. Either there is some electrical problems or fuel problems. He is using the what ever the procharger PSI comes with if that makes since. Im wanting to build up the moter myself im willing to buy a complete built engine rdy to go in. I want this thing in the 600 to 700 hp range. Last time i road in his car with it acting weird he smoked a 03 cobra pullied,and what little other mods by about 10+ car lengths. I love his car and just dont want it sitting wasting away. He had rdy to put in at 1 time some FLP exhuast setup but sold it . He was going to part out his car but i talked him in keeping it.
I have currently built up my 2000 gt with built dss sb/ patriot fully ported heads / comp cams and about to throw a 200 shot of nitrous in. Im making 309 rwhp and 309 rwtq with a very safe tune n/a.

okay, i dont know where you can find a 600-700 hp motor (LT1) prebuilt. someone else will have to help you there.
the biggest motor i found was here: http://www.golensengineservice.com/
might want to ask around about how reputable this place is. but i came across this sight a while back. they have a 383 stroker w/ 480hp and 513lb./ft of torque. you wouldnt really want to run boost on this setup though. it already has a CR of 11:1. maybe they can work with you to build a custom setup...
other options: if you want that powerful of a car, i would either talk to another professional builder of sort and see what you can come up with. or start doing a lot of research and learn what all its going to take to get you there (N2O or blower, etc.). this project is going to cost you A LOT of money.
BTW, what is your reason for wanting 600-700hp?

hmm... good luck with it.. and remember.. just dont get the biggest and baddest parts.. you have to match them and tune just right... i HOPE your not like a bunch of newbies i know with big pockets spending money and cant break 13's... but yeah.. good luck.. and do some searches to see what combination would get you to your wanted power..

LOL, i guess thats a reason. 
$7-8k isnt going to get you 600-700hp. at least not that i know of. even if you get that stroker like the one in the link, you'll still need a ton of other miscellaneous parts (intake, programming, exhaust, better fuel pump, injectors, throttlebody, etc.) and that will just get you the 480hp. and that block alone costs $6.5k + the cost of shipping. and what about rearend, if its stock, you might want to upgrade that. your going to need some good chasis support and suspension upgrades (depending on what suspension "upgrades" he already has done) to put the power to the ground.
trust me, 480hp is nothing to sneeze at. i think your underestimating what a "mean *** car" that would be if you set it up right. dont try and get 600-700hp for bragging rights. because it all aint going to matter if you have a 600hp car and running 13's in the quarter (doubt that would be the case, but you never know). your call though.

Good luck OOgt!! I'm in the process of doing something very similar. I'm having the internals forged, port/polished heads, and compression lowered next month. After recooping on the costs of that (bid is $3500), she's getting a turbo, injectors,pump, and tune...actually it's a twin setup. I'm not looking for quite as much power output as you are, but more like 500rwhp tops. The cool thing about a turbo system is that they're able to grow to whatever power you desire. But a sc would still be able to make the power your looking for with the right setup.
Nice Kill by the way on the Cobra...Love to hear about LT1's handing out a$$ whoopin's. Especially when they're on Cobras and the LS1 owners (the cocky ones anyway)
Keep us informed of your decision and blow by blow details of the rebuild.
