stock blocks
stock blocks what kinda power can you get out of a stock block with boost before it goes to hell.
can 1000+ be had safly, without the heads lifting and other problem?
and what would you recomend for parts to get over 1000hp.
right now im running a gen 1 SB and was thinking about converting to a ls style.
let me know what you guys think cuz i know theres a few of you big boost guys in here and i wana do somthing proven

An iron block ls1 should do fine at 1000hp. You'd need a forged crank (although some have gone to 1000hp with the stocker), billet mains, main studs, head studs, and forged pistons and rods.
Are you talking about Aluminum or Iron??? If you're talking about aluminum you could narrow it down to LS2 and LS1/LS6 blocks... It really depends on how good you prep the block...Also, 98 blocks (like everything else) aren't nearly as adaptable or hearty as later blocks are... Either way, both iron and aluminum blocks have seen above 1000rwhp but things like main studs, head studs(even going to a thicker than stock stud), and precise machine work help it become that much more durable...You may also think of installing a main girdle if this is something that you're really going to pounce on...All added insurance but it's pretty much a necessity at this level... Everyone has their own formulas but build it as strong as possible with the money that you have...
I've read a few times that under extreme boost applications the LS1 blocks will lose ring seal after a few thousand hard street/race miles.
The temporary solution was to rehone it, put in new rings, and plop it back together. Guess what? It happened a few thousand miles later again.
The real solution was to go to an LS2 block which stopped the ring sealing problems. An iron block is supposed to be the best production block solution.
There is a new GMPP LSX block coming out that can handle 2,000hp+ in March '07. It may be overkill .... but at least the option is there.

Go iron stock crank and forged internals for that kinda power. A stock block may hold but for how long is the concern. Dart is also coming out with a new LSX billet block so you can wait to see what that will do too.

ls1 engine girdle can hold upwards 1100+proven,no need to use heavy iron block.www.dmperformance.org
Iron block, stock crank, eagle rods, diamond pistons, stud everything, L19 bolts, has gone to 995 RWHP and into the high 8s and was reliable enough to drive around to car shows. One of the Speed Inc shop cars.
i seen W2W has a ls2 good for 1250hp. anyone running one of those?
i guess id like a motor setup that can handle up to 1500hp, so if i really feel the need i can turn the wick up. but im sure i wont ever turn it up past 1000.
so if the iron block is the strongest and they have ls2's making 1250 safely, could a iron one make it to 1500.
i guess i dident want to go to a aftermarket block, becuse its just a street car and it might only see he track a few times a year

If you don't care about the weight. Then go iron block. If you do then go LS2. Stuff either with a stock crank, Howards steel rods, Mahle or Wiseco pistons, ARP main and head studs, some good rings and bearings. Also have the mains doweled. Another thing that helps is to have the block half filled with hardblock.
This combo in either block will get you what you want.
The only thing left to do is contact W2W and send them some $$$$.

w2w performance relies on the girdle for holding major horsepower,an iron block with billit mains and dmp girdle should hold some serious horsepower id say at least 1650 horse + possibly more if block, heads,crank,rods, are cryogenicly frozen.they say when you cryo iron it becomes one and a half tmes stronger and aluminum gets three times as strong.mondello has a cryo chamber.
