Remember tho peak numbers are not everything.

I know it's apples to oranges, but the LS3 head flow numbers have to be right there with the 5.0 heads, makes me wonder what could have been if GM used the L76 variable timing setup but designed it for a big cam like ford did.

yep...........
i mess with them a little. i have a few $k in 415-420rwhp. i bought a TB that should add alittle more tonight. 425? i hope so.
the shoe is on the other foot now and they are relishing it. a bit of nose rubbing. a few boltons and 410-435rwhp is a big deal for mustang fans.
i feel nearly 100 percent confident ill make 440rwhp with bolt ons. its only 20-25 away.

Which part, the atrocious launch or the rape on the other end?

Not too bad for swapping in OEM cams. I'm assuming it's only the intake cams? Cuz that's what I usually see Mach 1s do. Like to see what that car could do with a set of gears to maximize the powerband, since it's shifted higher now.

...Playing field is level now, the 5.0 isn't a leap ahead of the LS3 like you are implying. And it could easily be back to the way it was if GM ever lightens up the Camaro like we keep hearing rumors about: 300lbs lighter on the SS and more aggressive tuning (which IS coming for the 2012 model) and the 5.0 will be chasing again.

Good kill!
The LS3 is a great engine. In fact the Camaro already moves out for how much it weighs. I would be in one right now instead of a 370z if it had weighed 300 lbs less than what it does now. The '10 SS manual is somewhere around 3850, right? Yeah, 3550 lbs sounds great to me! 
I would love to see a 5.0 with a 7500 rev limit. 
On a side note, is anyone else still impressed how (almost) identical the released Camaro looked like the concept? Go back and watch Transformers 1, which was a concept Camaro if I remember correctly. Extremely rare for Chevy to release a car so similar to the concept (well, for any car company really).

[/B]all ford would have to do is add a tune to the mustang. Reason why it has trouble running the numbers it should (stock) is because the stock rev limiter is pretty much right at peak power (6850rpm). Just a lil tune + raised limiter and you see why the new 5.0's are so much faster with just the aid of a tune.

Yep, definately traction issues but have since put the bigs and littles on the car with 275/50R15 555rs. Way better launching now. Go check out my vid in my other thread. Me vs a 2003 cobra tonight at the track.

Met a GM engineer yesterday at my hotel bar. He was getting ready to fly back from a cross country test drive of a "new mid engine sports car prototype. Before you ask, NO it's not the new vette... everybody asks me that." I can't say where I met him, or exactly what he said: not that he asked, but being with Boeing and intimately involved in the 787 flight test I know better than to get him into trouble. Also, there will be a couple minor mods to rear suspension.
Actually, the LS3 probably needs a mild cam upgrade to match the 5.0's amazing topend power.

naw, I'm thinking some kinda Cadi or maybe just a test prototype that will morph into the vette. The next gen vette hype is building so I'm sure he was under strict orders to not link the vette whatsoever to the car he was involved with.
Either way, it was cool as hell to meet the guy! Even if he was only mid 20's and wasnt any kind of gearhead: he struck me as a systems engineer or equivelant, alot like the boeing engineers I work with who deal with systems integration and such.

Oh I know I prefer the concept's thinner look over the chunkier concept but I'm sure they had to bulk it up to meet certain safety requirements for 2010.

Wonder how much a new SS would make if you cam'd it to spin to 7200rpms with a peak hp at 6800 like your 5.0? I'm thinking 520+rwhp if you did headers and tune. More if you went full bolton/ported intake. Damn that would be hard on the valvetrain though, and good luck getting it to idle smooth.
I know it's apples to oranges, but the LS3 head flow numbers have to be right there with the 5.0 heads, makes me wonder what could have been if GM used the L76 variable timing setup but designed it for a big cam like ford did.

EDIT: the " i mess with them" was referring to the 96-04 4v modular guys. it was a reference to the posters comment about them spending so much for less than a bolt on 2011GT. i harass them with my power numbers on the corral.
i wasnt implying anything. never mentioned the LS3. the question was "oh, thats why ford boys are so stoked". -paraphrased.
the next gen stang will be lighter than this one and a smaller car overall. i dont really care what the next gen stang is. ill be driving my new caddy. it (stang)could run 10's and i dont want it.
i know the playing field is level for ls2,ls3. never thought otherwise. but guys who are making the most noise dont own a 2011GT. i was referring to them rubbing noses. i cant wait for warmer weather so i can get out in the motorhome. its more comfortable than ANY car ANYWHERE.

96-98 cobra intake cams are the usual swap.
