and comparing a vette to a mustang is not unfair, since f-bodies all came with vette motors, and we are comparing motor to motor
Well there is no LS6 in f-bodies (unless it is a special dealership installed option)
There is LS6 blocks but that alone doesn't make power. Just thought I'd clarify that.
As far as comparing a ZO6 to a stang, that is a sin my friend and you need to repent.
Not even in the same ballpark, the ZO6 is ions ahead of the stang.

The only reason this is being compared is because the mustang would have normally been the enemy of the f body if it still existed. These motors are being compared because the cars should be compared, but the engines are so different. Someone mentioned the lt5... an old engine that showcased lots of new technology... and no boost. GM did not abandon the lt5, look at the northstar. The 4.6 northstar engine.. no boost, designed for the ultra smooth power band and idle demanded by a luxury car... 320 hp. Gm engineering is excellent. It is one thing to advance a standard with new technology, and it is a different one to refine an old one. The ls1 is a refined classic, it is tried and proven, and everyone know s it. This is the comedy.... a technological powerhouse IS being compared to classic small block chevy design... Its an embrasement to ford that this thread even exists, their engine blows. Had gm slapped a blower on the lt5 it would have been taking NEW enzos. Dont believe me? look at what lingenfelter has done to the lt5 by just retiming the cams... add boost and its ALL over. So how come ford so many years later, since they have already done these things, cant get these numbers?

The ls1 is the pinacle of performance for the 5.7 and in this sense is perfection.

A well written post. So much of what is written on this thread is by guys ignorant of a lot of facts. Fords mod motor truely sucks. It has horrible flow which is why it will not make power without FI.

MT just tested the new mustang stripped down "race car" with the 5.0 Cammer engine(a bored out na cobra engine) and it barely ran high 13's in the quarter. Sean Hyland is the guru of these engines and he only gets 400 flywheel hp out of the dohc 4.6. You can take a 4.8 ls truck motor put in an ls 6 cam and ported heads and get 400 hp easy. The europeans do the same thing all the time...they have high horsepower, high rpm multivalve engines that have low torque numbers and get poorer mileage than gms old fashioned engines. Also take one on these high tech motors and drop the clutch at 5,000 revs a few times ( which you have to do to compete against american cars) and the clutch and or driveline needs thousands of dollars worth of repairs. It reminds me of the spaceshuttle compared to how Burt Rutaan is doing it. Anyway thanks for some intelligent dialog. By the way, I have an 03 cobra with bell blower & 504 rwhp and blew the head gaskets at 9000 miles with only 14 lbs of boost. chuck

To bad I cant really post what I am really thinking, like I said before I cant type for **** or else I would type a book on how ford sucks with or without supercharger.

Okay..My .02..
Im a GM guy by nature..I know my car pretty well.
The last time I was at the track my LS1 ran 12.7xx at around 113.
I had an 01 LS6 cam,intake,lid,Mac mids/ORP/cutout,& 3.73's..the car put down 363 rwhp.
My brother bought an '04 Cobra...His car bone-stock put down 365 rwhp,& was just about as fast..
With a basic cold air,2.80 pully(14lbs),bassani catted X, Borla stingers,Accufab TB,& a predator 91 octane pulley tune..It made 451 RWHP..& ran 12.2 flat at 116...at nearly 6000 ft DA!
03-04 Cobras flat freakin' rock!
Are they better than LS1 powered anything?At stock levels they're pretty close..But who leaves their **** stock?I was amazed how easy it was to bolt on some serious power to a supercharged cobra compared to my F-body.
When I get my car back on the road,I'm hoping to just stay ahead of avarage pullied Cobras...Not to mention the fact that nearly every Cobra I know of in town is running at least a 50-75 shot.Encounter one with a KB or a Whipple & stand the **** by..They are stupid fast..(600 RWHP on 14lbs is not unheard of)
They will be legendary in the way of 86-87 turbo Buicks..
They do have some durability issues,as my brother can attest(the piston thing)But that's avoided by cooling system upgrades & minimizing top end banzai runs on hot days.
LS1's arnt immune from problems either..Bent valves/pushrods,high oil consumption,piston slap,etc..The cars they are installed in arnt perfect either..Weak 10 bolts come to mind. I've experienced all of those.
But after all's said & done..Im still a GM guy & I will make my **** work..It's lighter,more aerodynamic,handles well,stops great(with aftermarket rotors)..& best of all,it's paid for!
My brother still owes 30 k..

Stock for stock?
Uhh most likley..
My buddy with a '99 snake needed 4.10's & full exhuast to just keep up with me when I was mostly stock..
As far as I know,'03 was the first year Ford built a N/A 32v car(Mach 1) that was competitive against stock LS1 F bodies.(Not including 2000 Cobra R's)

Did anyone see the April 05' issue of Road & Track? Any Mustang article you see, just look for a Corvette reference, because no more Camaro, or Firebird to compare to since production has stopped. Thank god all Camaro and Firebird modding continues. Hats are off to all of you fine gearheads out there, they live! <This is what any Mustang kill receives from me, it is really a #1 for GM lol!

The reference to the Vette makes it in on page 65. Here is the reference paragraph in its entirety:

If you crave huge amounts of additional power along with Saleen's other alterations, that's entirely possible. Though not quite ready for press evaluation, Saleen's 400-bhp S281 Supercharged is claimed to go toe-to-toe with a C6 Corvette, and the S281 Extreme should be in the 500-bhp range. With all sort of V-8 urge, the better-located rear axle should prove useful.

Here is the best Ford has to offer so far that is tested, (same article)
Test results of the 440bhp GT-R and the 475bhp Shelby GT-500E they are $175K and $147K respectively. ?? The GT and Steeda numbers are not worth posting lol!
Mustang GT-R 0-60= 5.0sec. 1/4mile= 13.6sec. @104.2mph Wt.3700lb.
Shelby GT-500E 0-60= 4.2sec. 1/4mile= 12.5sec. @114.0mph Wt.3500lb.

Those Shelby numbers look like a stock C6 numbers for $147K. Get a load of the fat porky weights. The GT and Steeda top the scales at 3560lb. each lol!

Give me that C6 and $900 for a cam, valvesprings and pushrods, and I can make all those Stangs, even the Saleen S281 Extreme, see my taillights through a pair of binoculars, naturally aspirated, because they will need a telescope if the C6 gets a supercharger to make it an even playing field.

Gee, a supercharged LS7 C6 ZO6....................Ford will need to rent the Spaceshuttle with an uplink to Hubble to see those taillights.
<Ford

Some of you guys really have no idea what you're talking about...in more respects than just the Cobra.

This whole post reads like one at clubsi.com.

Exactly not unfair at all. Check my post above for the latest reference in Road & Track.

Anyway, give me Chevy High Performance mag. or GM High Tech Performance mag. any day of the week.

I see all the Mustang guys in the letters to the editor complaining when they found out that the new, redesigned Mustang was 500lbs. too heavy. Damn, can't blame them, have to blame Ford.

This topic has been beat to death. I have all the respect in the world for the Cobra motor's. Most issues with modded Cobra's have to do with the drivers not knowing how to drive, those positive displacement superchargers lay down massive torque in modded form right off idle, that makes them really hard to stick.

As far as the NA 4.6's go, you have to be willing to spend bucket load's of money on them to get decent power out of them. Go to www.modularpowerhouse.com & look at their heavy hitter's. They are dumping bucket loads of money in them to try to squeeze them into the 9's. It's taking built motor's & shitload's of boost for them to do it. They are getting there & I have all the respect in the world for what they are doing with their rides, but the cost associated with them to get in the 600 rwhp area is phenominal. My car is a stock bottom end, H/C + spray car that makes the power their heavy hitters are making for probably less than half the price of a built 4.6 & that doesn't include the blower's that they are using. I don't know if I've seen any NA 4.6 motor making a streetable 400 RWHP & that includes the pre 03 DOHC Cobra's.


Dollar for dollar, pound for pound, LS1's win in my book. Would I take an 03, 04 Cobra or any Gen II Lightning, hell yeah.

See my post earlier. Thats just a stock bottom end 302, not a built 302 or even a 351 thats built.

Built 351's N/A = 9's

Amen!!!!!!!!!!!!!!!!! I could not of said it any better than you. Speaking of ZR1, I raced one on I-10 going East between pensacola and Tallahassee. We did a roll start at Highway speeds (70) and climbed all the way up to 120. It was my 2000 SS vs a Corvette ZR1 and in the mix between us two was a Corvette LT4. Although the LT4 was strong, he did nothing when compared to the ZR1. The ZR1 simply jumped up and ran away from my SS like I was nothing. So believe the hype! They will run, even STOCK! The old man was kind enough to pull over and show me the method of my demise.Very impressive piece of hardware GM built. Ford, you guys a shamefully behind the engineering curve!

I won't. I'll bet on the LS1. Given that Cobras are already having problems, I don't think you can have long term reliablity without short term.

what rock are you living under?

try 2 x 5psi, C5's run 9 - 10 psi stock bottom end with a good tune no problem. put an ATI/Vortech on a C5 stock bottom end and 550rwhp is not hard. most start having problems around 12psi.

I love any car that is fast, no matter what it is. I loooove gm's but my bro is putting 478 to the ground in a civic hatch and I saw him spank a cbr 900rr on the highway 3 times other night. Yeah I know that they are not as fast at the track cause they can't hook up but it's still fast. I know most of you guys here don't like honda's but the fact is and I hate to say it but there are other fast cars out there besides ls1's.
