at the same time i understand your pricing here but ur gona get a shortblock and not touch up heads?? not throw in a blower cam? not upgrade rockers or head studs? go to high with boost got to worry about heads lifting off block. im pretty sure fuels system that comes with tvs prolly wont cover you with anything over 8ilbs of boost ( i could be wrong though). also your gonna need a clutch as well. also your gonna want exhaust!!

I factored that in...because to make the GT500 run with the built LS3 motor, you'll have to do headers, exhaust, ported blower etc...which can add up to $$ in the end...no you would not have to even touch the heads to make great power...these heads flow big cfm stock ~330cfm @ 0.600...head stud kit is $250...its not crazy $$, neither is a HVFP that will feed decent power...I personally have an auto ordered so at this point i'll risk it, several G8's have put 500+rwhp down with no issues and multiple passes, M6 guys will have to take that into consideration, but so will the GT500 guys as I would assume the stock clutch is not rated at 600rwhp?
I understand your point that the LS3 as it comes in the camaro is not actually designed for boost (being that its 10.7:1). Yes, the LSA would be a better comparison, but we don't have that, and may never have that so regardless of what may or may not be a good comparison, this was the comparison of the OP, and we are making it, and brass tacks suggest that if you strap on a TVS and CAI which would be 6K + $350 and that is ALL, you'd make 550 rwhp, which would for the $$ thoroughly plant a GT500 in your rearview....just saying.
$ for $ these cars are very close, stock for stock they are not...but as I've said, most guys that are enthusiast enough to follow these boards and argue pro-con are not leaving their cars stock, heck there are a number of guys that already have built shortblocks on engine stands just waiting for their car to get here.

Back in the old days of hot-rodding, having over 600+rwhp meant you had a car on the ragged edge of being streetable, but that is not so much the case these days. My car makes over 650rwhp on pump gas in the configuration I drive it in every day. (3" upper pulley). The car sounds, drives and tracks just like it did when I drove it off the showroom floor. I pull down a combined city/highway mpg average of about 18mpg and on long hauls, I can see 22-23mpg. In fact, unless you knew what was under the hood, you'd be hard pressed to believe it makes the power it does. No lumpy idle, quiet exhaust, etc.
I believe the same will be true for the new Camaro, especially if you go the s/c route. I do know a lot of GM guys who stay n/a and go the H/C/I route to make power, however, and I agree that in those cases, you are giving up some street manners for the additional power.

Basically, just saying that once you get to that power level with rear and drivetrain, you just never know when you might break something the next time you hammer it. Driving it in the rain you have to be extra careful etc. I have a friend who modded his cobra, he never had a problem til he started modding, then it couldn't quit breaking stuff. I never had a problem with my TA, or my TBSS still I started modding, then the problems come. No matter how much research, quality parts, expert craftsmanship etc is put into a build the probability of part breakage and downtime raises with every jump in hp.
Sure with FI you are more likely to be able to make serious HP, without the impact on daily driving vs NA...no doubt. But even with FI, when you start getting into the 600-700rwhp range on stock parts you are rolling the dice. We all have stories of folks that have done it, but there are plenty of stories of folks that have had problems also.
I just don't want some of the younger posters to read this and think they can strap on a TVS, headers, exhaust, CAI and tune make 600rwhp on their SS then go have no problems because its that way for the GT500...
