Heads/Cam vs Supercharger
OP, you dont need to run alot of boost to reach 500rwhp with a s/c. Ls1 can take a s/c fine just dont boost the **** out of it and you would still make more power than a heads and cam car with low boost. I was reading the ls1 crank can hold 1000 rwhp but the rods and pistons ect can hold a bit over 600.
If all you want is 440 rwhp you can do that with unported 243s and a custom 224 cam. I did my whole setup including exhaust for much less than what a set pof trickflows cost. Not to mention I have one of if not the strongest under the curve power bands I've seen from an LS1. 365 rwtq @ 3000 rpm and 399 @ 3800 rpm. Check my signature link for all the info. Not to mention I made that power with the heavy *** power robbing ls7 clutch.

True odarabla, But he said he puting rwhp and tq down low so with the proper gearing and traction it should run good. If i saw only peak high numbers than yeah different story.
Track times have nothing at all to do with driveability or power under the curve. Last time I check I don't drive above 4000 rarely ever. I agree peak numbers mean nothing at all. If you go to the same dyno and get a baseline as you add mods you will see gains / loses in your power bad that the track would never explain. Good heads and a cam specced for your application is what its all about. I know how big cams run too, my buddy has a trex cam in his gto. Nothing I'm interested in daily driving.
Atleast dynos have correction factors. Some read high some read low. Comparing track times is about as bad as comparing dyno numbers. Timing system, weather, car setup, driver, traction, weight elevation, fuel way too many variables to compare. Compare similar cars at your track is about the only fair comparison.

Sorry man but I disagree with some of your post although I do agree with the same track statment. You are correct, my car will run different at your track verses the one I run at over here but true h.p. will get you down the track faster. Example: My buddies car is lighter than mine, stripper LS1 Formula A4 and he puts down more rwhp I made 447rwhp and 403rwtrq verses his 478rwhp and 453rwtrq. I ran a 10.90@123mph and he ran a 11.63@118mph on that same night. He put down better peak #'s but I had better across the curve #'s which made for a better performing car. The funny part is he kept telling me how much of a factory freak he had.. lol

Verdad Gallardo Just matter about the combo your running. I seen 400rwhp cars beat 450rwhp cars and so on. Driver mod is a must but some dynos are happier than others. But I dont see a reason to get afrs or trickflow when you can get ls6 heads that flow almost as good as them for less money. Correct me if im wrong.

Sorry buddy but you are wrong about the LS1-LS6 head flowing as good as the AFR's and trickflows. If this were the case then they would be out of buisness. I am not saying you cannot make good power with the stock heads but you are gonna make more with the after market head. Besides with the trickflows you can run a bigger cam without the trouble of PTV.
just looking at flow numbers shows my stage II 243's flow better than the TFS220's. it all depends on who you go with for porting and how much your willing to spend. course it'll be a while till they go on, but the cam will be a custom grind, probably in the 22X/23X range
