Nice kills and I'm guessing he overinflated his numbers as well. A lot of people I run with tend to do the same thing. Its annoying but its pretty common. Either way, his car was definitely strong because of the mods he had and the motor he started with.
However, his tires were 28.8 inches, which is WAY too tall, slowing him down tremendously and bringing whatever his gear ratio was, to a much more stagnant ratio. In your opinion, do you think if he had some normal 26" tires and his extra passenger was yanked, that the roll races wouldve been closer or he even edging you out? That tall of a tire absolutely KILLED his gearset.

Thanks guys, was pretty fun races. Wish the Cobra owner knew his car better. I would have liked a piece of that.
Sept-Nov when it cools off. At midnight here it is still close to 90*
Yea I'd love to get into some of the racing where you are. Seems you guys are always having a blast! Let me know what you get next and plan to do that way I can mod accordingly. LOL
He definately had more than 420-440rwhp or else he had alot of weight taken out of the car. I don't know which one but it sounded right to me. A stock LS1 motor with a cam can make alittle over 400rwhp...the LS2 is a 6.0 so give it alittle more...heads are probably better and then port them...sounds like a 450-460rwhp motor to me. 
Too be we couldn't get you up here for some runs before I sold mine. Oh well, I'll just have to build another one soon. 
Good Kill Stoppie! I'm doubting his 472rwhp claim though. Sounds like someone was drinking the coolaid. Norm for big cam, ported heads stock intake LS2 GTO's is 420-440rwhp. A FAST or heavily ported stock intake will net you another 20rwhp... porting a LS2 TB is worthless for power btw.

Why are you guys saying this? He already said he didn't know about the intake.. It could have a ported 102mm for all we know.
If he was full weight and only made 430Rwhp it would have been ugly.
470Rwhp is not out of the norm by any means with a 346/mid-large size cam/heads/FAST. So take that into consideration and add a few more cubes.. Why could he not be at 470Rwhp with a stock intake/good ported heads/cam/UD pulley/good flowing exhaust/etc etc etc... Not to mention even if you don't believe that, it could have been a generous dyno by 10Rwhp or so. A cam only ls2 will make around 430Rwhp or so with a good sized cam (like Stop said this had)... Add a nice ported set of heads- ~30Rwhp... There is your power.
I see no reason at all why he would lie... And why 472Rwhp or whatever it was? Why not 475 or 470Rwhp. I have zero reason not to believe it.

Run of the mill H/C setups on stock cubed LS1 cars typically make 420-440 with supporting mods if they still have the stock LS6 intake.
FWIW, guy who helped tune my car had a 2006 GTO H/C/I (ported 90/90) and put down 502rwhp with an automatic trans w/3600 stall. These were some nice AI 243 heads, and he is a tuner, so he has probably spent plenty of time on his own car.

Good races.
My take on the rest of the BS:
-Lots of mild LS1 owners and exhaust only LS2 owners commenting on LS2 power gains in here. As mentioned above, a big cam only LS2 can go 430 through an A4 in a GTO in average DA. The LS2 is a beast.
-Ported LS2 TB/Intake can net up to 15-18rwhp with an average of at least 11-12. TB porting is about 3-4rwhp of that and mostly accounts for improved throttle response. I dropped a consistent 1.5 tenths and gained 1.5 MPH every run from porting the TB/Intake, rest of car stock at the time.
-M6 guys who want the big donkey dick cams but wont/cant launch it out over 5,000 RPMs should leave them to us big stall A4 guys (or just avoid digs).

ummm, No. A wildly elaborate H/C setup "might" make 470whp on a 346 with stock LS6 intake and TB. But you're talking 1 7/8" headers, cutouts, heads flowing in excess of 330cfm AND milled down for a nearly 12.1 DCR, custom camshaft, and an aggressive tune.

An AFR head (untouched)/custom cam/good tune and full bolt ons (stock ls6) can/should hit 440Rwhp (and then some).
A decent setup (nice heads/decent cam/FAST/bolt ons/good tune) should make 470Rwhp with a 346... An ls2 should hit that with "shitty" heads.

This GTO did not make 420-440rwhp. It would have been much uglier. I think his setup was done right, his car was just very heavy I think. This guy was no small fry either. 6'2 I'd guess 250lbs...

His name was Mark.

No idea. I remember a guy with a red(ish) GTO wanting to run my old pewter TA a few years ago until he found out I had nitrous. He was hispanic though so I doubt his name was Mark.

Wow hope Im not part of the blanket statement just because I "only" have exhaust.

Just interesting that all the facts always come from the near stock guys. Just sayin. Dont have to feel attacked over it but is it not true? The SR&K section is full of near-stock genius. All anyone has to do to build a heavy motor is come into this section and read a few posts from the near-stockers and its 9 second car all day from there.
That leaves out a ton of variables. Namely, I would bet that its not in the 240 range of duration or even the high 230s. Were talking about big cammed LS2s here, like MS3/4, Polluter, Mega Death....etc 240 duration range cylinder counters.
If you made 422 cam only on one of the big cams your either in very high DA or something isnt right.
Either way I bet any big cammed LS2 GTO is not expecting a close run or to get yanked by a N/A SN95. That was a good showing by you. Would have liked to be there to see it go down.
Nice kill.

I agree with you. The LS2 is a nice motor. You guys have it lucky. Aluminum block and a very nicely designed pushrod motor. I'm very jealous and wish my 5.0 was along those lines.

Talk about blanket statements.
Aren't you just cam only?

How far are you from Shady? My buddy won the Import shootout down there last month, in a Dodge at that.

Beyond that its just an opinion so take it for what its worth. Every 50 page BS thread in this section is full of opinions and bias and its just the way it is here. You'll either agree with me, stay neutral, or disagree that fine but the part about speaking on what you have and know is what it is, so by all means, please tell me exactly what combo will give an LS2 GTO what through what trans, I apparently dont know what I'm talking about here.
