ls2 600 rwhp
ls2 600 rwhp is it possible to have a 600 rwhp GTO with a stock cube ls2??
I don't mean stock bottom end I mean with better pistons, rods, heads and crank.
what do you guys think? If no then realistally how close can I get to this goal?

yes, we made 809 whp on a cammed and stock bottom LS2 in a twin turbo saturn sky!

Now hitting 600rwhp while N/A with a stock cubed built LS2 would be a pretty good challenge. I know that low-middle 500's have been done while N/A but I don't know about 600rwhp. I am sure someone has, but it probably was neither a cheap build nor considered "streetable".
I know I can get 600+ w/nos or boost. Hell my stock bottom end ls1 GTO put down 620rwhp on a 150 shot. I want to build a stock cube engine capable of 600rwhp(ish) then spray the ***** off it(250-300 shot)
You're going to need lots of compression, badass heads/intake, lots of cam and lots of rpm to make 600rwhp N/A with only 364ci. That's starting to flirt with 2hp per cubic inch, and that ain't cheap to do no matter how you shake it.
Are we talking rwhp or at the flywheel? There have been several LS2 stock-cube builds that have been over 500rwhp, which would translate to almost 600FW hp (assuming 15% parasitic loss).

I'm looking to get as close as I can to 600 RWHP. I talked to livernois and they say to set my sights a little lower like around 500-525 RWHP, then spray it

Even 525 RWHP with stock cubes is tough and it will not take that big shot anyway because of what I mentioned above.

Just build a 427 for the same amount of money you will spend on a serious 347 build...then you're good to go and it will last.
Use an LS1 block, they are the strongest blocks of all the aluminum LSx family of blocks.

You're not gonna make 600 RWHP with 347 cubic inches.....unless you spend $20,000 and use race gas with a solid roller.....and a stock sleeved block won;t last anyway, you'll need a resleeved block so you have good wall thickness for that GIGANTIC nitrous shot you plan to use, so you don't blow head gaskets every time you spray.

isn't a ls2 364 ci and a ls1 347???
as far as the GIGANTIC shot as you stated above this is just starting to be a man shot hell I'm trying to squirt 500 plus to the thing
Best advice you're gonna get right there.....you're talking about an all out high maintenance race motor to hit 600rwhp n/a with 364ci.
Nick Williams has come close to 600 N/A on his LS2 Vette with a plastic intake even IIRC....

Oops, yes.....just so used to typing 347ci when thinking a stock cubed engine.
500 shot........thats a serious purpose built engine man. Probably not gonna last too long, meaning regular rebuilds periodically.
Why are you stuck on stock cubes?
Its easy to make power with big shots, but why not build a larger cube engine so its not such a full race build with stock cubes, and have a nice long lasting engine to spray.
My friend had a 422ci iron engine built by a local shop here, it made 535 RWHP N/A on pump gas, and 880 RWHP on a 300 shot with a stand alone tank with race gas in it that sprayed his DP system. The engine is still fine after 6 years in his daily driver.
.
Even 500rwhp will be doable with a higher compression h/c/i build. Then throw a small 75 shot and that will easily net you 600 rwhp.
Or you can settle for 450-475 n/a and do a slightly bigger shot.

What's the reason for wanting stock cubes? A stroker will give you the power with much more tolerable street manners, with no real increase in cost compared to a forged stock cube rotating assembly.
