There's no need for a 7.0L motor when it comes blown from the factory.

is that you can't fathom the fact that the blown 5.4 ONLY MADE 550hp (at the crank). You think that is some great feat. Shoot, I made more power and torque than that with an LS1, a $400 cam, and a $500 nitrous system. And some people have a need for a 7.0L: THEY CAN STILL SUPERCHARGE IT.
And yea, the tiny blown 4.6 DOES have trouble handling the LSx motors. The LS2 makes more power N/A, as well as the LS6. Your comments don't even make sense.

A pulley swap and a few bolt-ons will net at least 450 @ the wheels no problem....for literally a few hundred bucks. And with the bullet-proof bottom end they can gulp all the nitrous in the world as long as it is tuned right to smoke just about anything out there.

Here is a C6 manual vette and he got 347. My only point is the 03-04 Cobras and their "little" 4.6 has tons of potential out of the box and can handle a lot more as long as it is tuned right, without having to upgrade anything on the engine itself.
Peak numbers are useless. The LITTLE 4.6 takes too long to make power, and seems to lack torque. I rode in my buddy's 490rwhp Cobra and was unimpressed with its thrust down low. I also outran a stock '03 with only intake, lt's, and exhaust. I'm just going off of experience with my old LS1 against '03 Cobras, modded and stock, and for the power they "have," it doesn't show up at all. I've consistently outran (from a roll - so all power) s/c Cobras with more power than me. The most powerful one I came across (before I sold my car) was a 550rwhp '03, which I pulled 2 carlengths on from a roll with my 482rwhp SS. However, my SS had the torque to keep the power there the whole time. I've seen modded '03 dyno sheets and it seems like they lack the torque to make a lot of power under the curve. They start slow and spin up to a nice peak number. My SS made over 400rwhp at 3,000rpm, once again, with only intake, exhaust, mild cam and nitrous.
And I'm not saying there is anything WRONG with how small the 4.6 and the 5.4 are, I'm saying that 550 crank hp with a blown 5.4 isn't anything special or out of the ordinary. Any $24,000 LS1 Z28 with a cam and nitrous can make that kind of power. Take away the 8psi boost of the supercharger, and your Ford GT 5.4 is only making an estimated 356hp at the crank. That's why I'm saying it's alright, but nothing to brag about.

Sure they can still supercharger the 7.0, its a BADASS motor. You can also throw a pulley on the GT though, and do whatever you want with it. I'm sure you have heard that the 03/4 cobra's were tested at 800-900 hp in production, the GT is rumored to be tested at 1300 at the flywheel!!!!!!

YOUR COMMENTS DO NOT MAKE SENSE
Show me your "flat" torque curve. I've looked at the average modded '03 curve, and it's pitiful. I've ridden in them, and the torque is not there. You can say anything you want, but no s/c cobra has ever given me a reason to think they have any appreciable torque under the hood. From the ones I've ridden in, I kept thinking to myself, when is this thing going to pull harder? And they never do...
Maybe I'm just used to the 583 ft-lb my SS had - THAT makes for a flat torque curve.

I think the new "retro" styles for the Stang's are ugly as hell. I'm going to stick with my 03 Cobra. No point in re-financing a $45k Cobra when the '03's already paid off and modded that probably will be faster then a stock '07.
hmm a 465hp car for 30k.... well ill take mine with on options and all the cheap **** to save $$ and wieght and the solid axle... then ill do like the 03 guys and just upgrade the blower or run a pulley.... hopefully this car would take care of the 03's flaws... which are imo, irs, and weight wieght wieght!!!!!!
and every mustang seems to dyno really high for the times it runs.. hell it may run 10.00 but when u see the dyno #'s usually u wonder why it didn't go faster. if ford could correct a few of these things, and that idiot lutz at gm doens't change some things soon i may be making the swap....
superchared monte carlo = 30k vs superchared 465hp rustang for 30k vs 70k z06... well ill prolly have to get a stang now want i, that or a skittle.
on a side note that mustang chop is dog *** ugly.. but who is really gonna care, when the stang is the only option left?

, or never even owned the car
