I would love to hear your opinions about how my car is doing.

You have a ported intake, ported throttle body and higher ratio rocker arms (all of which the OP does not have, yet shows 15rwhp higher than you). I'd definitely expect to see the 410-415 rwhp that you reported having.

How much timing is A LOT of timing?

Changing springs would certainly help with valvetrain stability and maybe even help make some more power but the car would unfortunately then also fall under the 'internal mods' sections of any recognized 'fast lists'.

He also has A LOT more restrictive exhaust, a callaway as i have a varram, i have less rotating mass, fidenza flywheel, underdrive pully, and an EXTREMELY aggressive tune to his predator canned tune.. How is it that you gather that just because he has different mods than me he is "suppose" to make more power? you are looking at just what the mods are instead of spifically WHAT the mods are... sorry but all intake exhaust tune cars are not the same...

Well then i guess it was dumb of me to ask your opinion then..

Well i'm glad i don't have your car... like i said don't count on that being an accurate representation of the car.. were you having to lift your clutch pedal off of the floor on those passes too?

Where were all of these doubters when Gary's car made 530whp with bolt-ons on a "Heartbreaker Mustang Dyno"?

One big difference...Gary's car backs up the dyno numbers (whether they be the 520rwhp he generated on one dyno or the estimated 550rwhp that someone thought he'd make on another dyno LOL) out on the track. So most realize that there is really very little to doubt unless Gary has internal mods that he's not divulging...but I know him pretty well, he simply doesn't roll that way.
137+mph ....time slips don't lie.

I guess Gary has the supersecret bolt-on combination that nets him 40 more whp than the OP does when compared to the other 99% of C6Z's that have the same exact mods.

Good point and I think I see where you're going with this...that if we can all accept (and most of us do) that Gary's car makes more power than other similarly modded bolt ons only C6 Z06s then why can't we believe that the OP in this thread is doing the very same with a bolt ons only LS2?
And honestly, I believe that anything is possible hence my 'track results prediction' a few pages back. With 430rwhp/415rwtq this car should FLY. But if it goes out and runs a high 11 at 120mph on a tire with a new clutch in fall/winter air then it is going to become a lot more difficult to explain (ie: believe) the dyno numbers, no?
Simply waiting on track times at this point.

Wow Though this thread was done. Discussing dyno sheets and trying to pick them apart you guys will be typing until hell freezes over.

It is about time the OP fix his clutch and take a few runs down the 1/4 mile, BTW it might be a good idea to weigh the car too.

With regard to bolt on cars that go fast......there are many little things that make one car a bit faster than another..... it is all in the details does anyone keep a log book another example: how many guys index their plugs.

Mr. SpecialSause, you said it yourself the dyno results were uncorrected, so how/why are you so adamantly defending that the car makes the power it does when, by your own admission, there isn't accurate data to compare? (although comparing dynos is pretty futile anyway)

Why so secretive about the timing? Also, which type/size headers do you have? Where do you have the cutouts mounted? What brand flywheel and do you know how much lighter than stock it is? Perhaps this info could help give us some insight why your car makes the power it does. Like many things, it's the details that can make the difference. So help us out here.
