Can a stock 346ci aluminum block BUILT UP handle 800-850 rwhp on boost?

Do an LS2 block with stock crank and good rods/pistons and have no worries. The LS2 block is stronger. Stock cranks are good to 1000rwhp+ with proper tuning.
PM Steve at Race Engineering in Socal who resleeves these LSx motors for his explanation of differences between LS1/LS6 and LS2 motors.

pick up an LS2 front cover assembly and cam gear. Done.
I stayed aluminum block FWIW

"The LS2 block will require a different valley cover, front cover, timing set, cam sensor, knock sensor and all associated gaskets." This is a direct quote from Nick D'Agostino from Victory Racing Engines...It's just I was going to consider the LS2 also but he enlightened me on this...He builds way more engines than I do and this isn't the first time that I've heard this but since Harlen says no then I would guess that it's okay...Damn internet...Too much info...

WOW........ Harlan knows exactly how i feel about Nick...........
ANYONE who worked For APE i would never buy a motor from...... after the 3rd one and Nick saying... no man it will be fine i built that one......
Just like Slowhawk said.... ANY motor that pushing that much HP with need to be refreshined often..... even if its just rehoning the cylinder walls and fitting news rings.
FYI im a Iron block now and when the time comes ill go back to ALM.
you can have that 90lbs back....

like i said, im not saying it CANT be done, it obviously has and will continue to be donbe. Im just saying its much bigger of a risk going to Al, for the b4mentioned reasons. but what do i know, im only quoting an engine builder that does a good deal of research and development for gm 
good luck with whatever route u go with

my best et pass was an ls1 block, it had to be re ringed 1/2 way though the year of racing and street drivng, pulled it after the rings wore again.
then i had a iron motor that worked great until i broke a bunch of pistons, never got around to needing rings, def. had more miles on it.. at more hp.
now i have an ls2 cuz its stronger and i took the oportunity to get the weight back off the car. i'm driving around at about 800rw on pump gas/meth right now, 7k miles and all is well, but no racing yet.
its really not a big deal to accomodate the ls2 change.

Exactly.
Give HPE, LME, TSP W2W a call....
The person i used inst a sponsor so i cant post who.
If i had to order another short block id go with W2W in a heart beat...
My brother had nothing but good things to say about the short block he got from TSP.

Cool Kyle...good looking out man...Nick seemed like he knew what he was talking about but we didn't get too specific...It wasn't the first time that I've read or heard that you needed to incorporate the new sensors but apparently it can be done...All I can say is that we're all human and the day that I no longer learn something new I'll be dead...Thanks for the info guys and the heads up..I'll look around some more...I'll be heading home from Iraq shortly and I need to get a shortblock underway though...Thanks

LS2 blocks have siamese bores, which is the main reason that some noted engine/FI experts advocate swapping to one.
What I HEAR with the LS1/LS6 stuff is that at high power levels the bores start to distort, the rings are fine. The bores will get out of round and then you lose ring seal.
I guess we'll see what my 2001 LS6 block looks like this year. I'd like to get a full season out of it.

98TurboLS1-
With any engine your looking to get built for your car, specifics are the first thing you need to start going over. You never want to just buy a package deal or from what we've seen get into a "group purchase" engine deal. Not the way to go about building a motor at all! That is the most important part of your car's future potential, why waste it on saving a few bucks?? Although it may seem like your spending way more on something you can get somewhere else for cheaper, it's the quality you pay for. The guys at W2W and the gentleman that just built kyle's motor have been building great race proven championship motors for years, you can't buy experience with this stuff.
Feel free to give us a call at the shop and we can help you out in getting a great short block for exactly what you need. The guy that built kyle's motor is VERY reputable in this area and I can get you directly hooked up with him. If you want to stay with a LS1Tech sponsor, I would for sure use W2W first, those guys are amazing and very establised over there. Three of our current projects are getting W2W Long Blocks. We use W2W also for our future engine dyno testing and some chassis dyno stuff. Regardless, you can't go wrong with either of these.
Like I said, feel free to give us a call at the shop and we can help shoot you in the right direction.

Well thank you very much...I'm actually contacting W2W and seeing what they can do for me...I would call you but it's a DSN phone which is like an ancient styrofoam cup setup with a string in the middle...I'll definitely give you a call in a month when I'm back in the states....Thanks
