What is the big deal where. Stock for stock they are both great cars. Both cars with mods will be faster. There will always been one faster then you. Problem solved.

Good post and I agree with most everything! The blanket statement about Lazy wasn't really meant in the correct context. I was just trying to point out to him that instead of building a good NA motor they went smaller with the blower route with more goodies, kind of like they wanted to kill 2 birds with one stone. But I do agree!

BTW, I do like how laid back the atmosphere is here and people can actually have discussions, and that the heated arguements have their own area. Sure makes for a good rivalry between here and the other LS based forums!
The MOD 4.6L just didn't produce enough power N/A, if Ford didn't go the blower route I would still own an LSX car.

What's funny is hundreds of people, including myself do high speed pulls with no problems. There are instances of people who run into problems and automatically all Cobras can't do high speed runs. Like with any platform it has it's weaknesses and for these cars it's heat, do the right supporting mods with an excellent tune and it shouldn't be an issue.

Yeah, and stock Cobra motors have held 1200rwhp. 650rwhp with cast pistons, an aluminum block and high compression is not a setup meant to last. I know it's been done, just not sure how long it lasted.

Stock Cobra at 8-9psi equal 370-380rwhp and Stock LS2 GTO at 8-9psi equal 515rwhp, So the LS6 heads will see more power than Cobra heads and they flow better.
Boost is only a measure of restriction, of course a 6.0L will make more power per pound of boost than a 4.6L. Further more, you're comparing 370-380rwhp from a stock eaton on a low compression motor, to a more efficient aftermarket blower on a high compression motor.
FYI, a 4V Mach1 with the stock high compression motor will make around 500rwhp at 8-9psi with a procharger or something similar.

show me an example of a stock bottom mach making 500+rwhp on 8-9psi. they're usually 460-480 at that boost level

Again 4.6L vs. 6.0L.
I don't see why it should be so surprising that the larger motor would make more power with equally efficent blowers running the same boost. Thats like me saying that at 16 or 17 psi I will be making more power than a MKIV Supra at the same boost level. I have a Honda sized motor of extra displacement, and we all know how powerful Honda's are. Who really cares as Supra's can run much larger boost levels on pump or race gas than a Cobra to make up for it? We're talking 40+ psi in some cases if I'm not mistaken.

LS motors are very good, but by the same token their owners can be pretty bigheaded about their cars(particularly towards lesser Mustangs) themselves. People like to think of what they have as being better than the competition I guess.
x1 billion...
I think people sometimes toss me into that category and who knows..maybe I am bigheaded and an ass sometimes about LSx cars but I tend to think I am pretty fair when it comes to their performance.
Of course I managed to purchase 'the fastest f-body I've every seen' so maybe I shouldn't be the group spokesperson.
You can put a GTO in 5th and top out and hold it for several miles...You can't do that in a Cobra or it'll seize on you.

Stock Cobra at 8-9psi equal 370-380rwhp and Stock LS2 GTO at 8-9psi equal 515rwhp, So the LS6 heads will see more power than Cobra heads and they flow better.
3 grand on a KB + supporting mods still can't hold a candle to a C6Z with Longtubes/tune.
ya your comparing a ****in 505 HP vette to that weighs 3200 lbs to a 590ish 600HP 3800lb cobra man weight is gonna decide that race cause chevy plays the ricer game power to weight so once again not apples to apples man that's like saying your C6Zo6 woun't touch a slighty modded Ford GT man there both super cars so money doesn't matter man or a ****in Saleen S7 I mean come on man
All I gotta say is I will take my little 5.4 motor put a set of forged rods on 4Valve heads with a big blower and force a shit ton of air into it and destroy your ass all day

Why the **** would anyone put a car in 5th gear and hold it that is the most lamest thing I have ever heard. Another thing redneck I hate to hurt your feelings but your LS1 Chevy motor will never see 650HP on Stock Rods and Pistons I know the Heads won't see it so better go build first man.

I'll take my lil 7.0 motor, Heads/cam it and spray a 100shot and smoke you all day long while still retaining my stock bottom end while you try to make 850+rwhp just to try and keep up with me.

There was a guy in my town 2 yrs ago that had an 03 Z06 with stock bottom end, LS6 heads (317 CASTINGS), g1 cam, LTs, procharger d1sc and tune laying down 668rwhp on 12psi with Alky/meth...
Mike Murrillo also had an 01 Z06 with stock bottom making 666rwhp on a 200shot direct, H/C/I and ran 9.9s @ 145 with stock bottom end and stock tranny.
what's that about LSXs not being able to hold over 650rwhp?
, GM built an awesome NA motor with lots of room for more power. As stated above there are plenty of H/C LS cars that are at the level of a ported pullied cobra.
Tyler
honestly the funny thing about your prized gm motor. once you go with your head/cam/intake route with it theres really nothing GM left about the motor besides the lower end. a ported blower cobra still has everything that the motor came with from the factory. so dont say gm built it. say AFR/comp cams and FAST built it.

the ls6 will see more power due to the fact it has a lot higher compression and 70 more cubic inches. the ford "c" head flows better.
for comparison a stock mach 1 makes 305 hp and 320 ft/lbs.
a stock ls1 makes what 320 hp? ballbark? the mach 1 has 65 less cubic inches and less compression.

ahahahaha I remember my auto days... a lot of losses...
The only reason trap was brought up is Cobras are notorious for being difficult to launch and a lot of people run from a roll for that reason. Going from a dig I say whoever has the stickiest tires wins.
See I heard the other way around on this one. Meaning the GTO's are harder to launch and the Cobra's are a tad bit easier. Or did I hear wrong?

Here we go again, the thing has a supercharger and it's invincible, every SVT driver in the kill section is Superman and everybody else sucks at driving, Cobra owner or not, and all upper pullied terminators are trapping 123-125 mph, shit gets old really quick, don't know how some fackers doesn't get tired of it
And since we're playing the e-penis bigger than mine BS, GM already slapped superchargers in the Cadi and Vette ZR1, so if GM doesn't go bankcruptcy, the aftermaket should catch up fairly quick, as well as the tuning side, so there you go Ford pussies, bigger engine with the abililty to hold boost from the factory, less weight, except on the cadillac, but it's 4 door vehicle, and you can have it in both flavors, manual or auto , as for the vette, well, that one is been kicking Ford ass for a long, long time, and NA to top you fackers off.....

Two things about that, first is you can also P&P heads. Two, all the GM motors can upgrade with GM parts. They have GM hot cams (even though after market are better) and many LS motor folks upgrade to another LS head. IE LS1-LS6 heads, LS2-LS3 heads, and the LS3 and LS7 guys have great heads already and they just P&P them....
So yeah, GM built sounds like a good word. I think I have heard of cam only LS3's running around with 500whp, anyone else hear this?
Besides, do they change to another Ford Pulley or is that after market? Let's not get technical here! I'm just comparing stock number at the wheels with the stock lower end.
not stock
Like with any platform it has it's weaknesses and for these cars it's heat, do the right supporting mods with an excellent tune and it shouldn't be an issue.
Do you own a Cobra?
