500rwhp on a LS2 stock bottom is possible and doable.
Now you could possibly get close or just over 500rwhp with a L92 combo consisting of the LG G6x3, Ported LS3/L92 heads (shaved to a 64cc chamber to keep your 11:1 compression), Ported LS3 Manifold, Ported TB, Yellow Terra 1.7" shaft mounted rockers, electric pump (can't hurt), and all the other fixings (headers, catless mids, udp, etc).

Reason: Just thought of the other half.
Nice size cam, intake manifold. Well thought out exhaust and you will get it.

i talked to jason and trevor @ texas speed and they said pretty much the same thing. its possible but it will take a very well coordinated and maxed out effort. he also said that the valves on the L92 heads are so big that u cant run a very large cam w/o cutting reliefs in the pistons. so im rethinking my plan in the future to do a LS3 stroker with LS7 heads. i think 600whp would be no problem with that combo.
Yes it can... See Sig Below! Stock bottom end 500RWHP N/A spinning to 7000rpm using the (Junk) Dart 225 heads untouched.
That was before the:
Shaft Mounted Rockers
Lightweight Twin Disc Clutch
Prototype OTR Vararam Cold Air Intake
& through the stock air box.
I am also looking at getting an electric water pump & a carbon fiber drive shaft just to get a little more out of it. I feel 515RWHP on stock bottom end shouldn't be too much of a challenge. Good luck!
Kingsize - what intake setup are you running? Is that a GMPP piece I see in your sig?
Careful what you say. Bigger is not better like with the cathedral ports.
Well of course. This was just the majority of what I have seen on the dyno, etc. but I agree with were you are coming from.
Now, to argue and work so hard to get a few extra horsepower to break "500 rwhp" is a waste, as I would rather just want a car that runs hard at the track. No matter if it makes 497 rwhp or 505. LOL
^^^^ Good point!
The thing is in order to get 500rwhp out of a small engine you need to spin it to the moon. That makes the power in a non usuable range for 98% of the cars driven on the streets. Really its a gimick. Power under the curve in a useable range is much much effective. You can run the L92's but you need a properly spec'ed out cam and that doesn't mean throwing the biggest stick in there you can find.
