Is it a better bang for the buck?
Can it hold more horsepower on stock bottom end?
You throw a procharger on an LS1, or on a Cobra, which is better?

I know this is also a useless debate, but they really get agrivated when I say things. I do love fords as well, but you know when it comes down to 1v1 we gotta choose GM. I just want a better argument, any other reasons you have would be great.
TIA
Dont forget the new Z06 has all ready skined the viper and I am shure it will also clown on the the gt40

those cobras are blown and the ls1 still whoops it and the ls1 is n/a. the ls1 is more bang for the buck.. its so massively expensive to mod a cobra motor. also the cobra motors are physically massive, i think someone borught up in a different thread that they were as big as the 429 boss motors.

ok i love the ls1 but we all know that a stock ls1 won't hang with a stock 03-04 cobra. I think we gettign a little ahead of our selves here. Yes a cam head ls1 will make a **** load of power, for far less money that it will cost to put heads and cams on the ford. But then again they don't need heads and cams they'll just simple turn up the boost. With unlimited money, the ls1 is better, easier to work on lighter and like everyone knows there is no replacement for displacement.

Yeah no kidding. Granted we're all GM guys here but Jesus...let's ditch all the biased feelings aside...the Cobra is still a respectable car.

LOL. you guys crack me up. Now i'm a ******* for respecting where respect is due.
And 5.0's that are only capable of 12's??? Now that is reaaaaly funny.
I'm 1/2 way across the world and there are 2 guys here with turbo 5.0's into 9's (And believe me when I tell you that the only track we have here reaaaaly sucks)
You guys should get out more often.

Bottom line guys, never underestimate anything or anyone and there is always someone faster than you and NO, it is not always an LS1.

I still want you to back up your statement that Ford detuned the 302 due to insurance reasons

Fact is you're talking out your ***.

Both engines are great in thier own way. The LS1 is more flexiable though less complex to work on.

Well, since you're flaming, I'll use the American way to respond and ask you to prove that what I said is wrong, if not take it for what it is worth or file it in bin 13.

are they stock blocks? ...kind of doubt it, considering on boost those blocks tend to split down the lifter valley. a STREETABLE 5.0 is crap..

Face it though. The 05 Rousch Mustang for 25K at the dealership is a hell of a price for a brand new car with the potential that it has.

You are comparing a 5.7 L with a 4.6 L, like I said above I've seen 351 Boss ponys and they were rated at 320 and that was back in the late 90's when LT1's were making 285.

Why do you think I own a LS1? But i can't deny that the new 4.6 makes 300hp either.

Well here is one you can use. One very bad flaws on the 03-04 Cobra and this is fact. They installed cheaper pistons to help save cost and also put teflon coating on them to reduce piston slap on cold start ups and help on movement. Bad thing is it heats up easy and can melt causing damage and ruining the block. Cobras are starting to have problems with #7 and #8 pistons. How do I know it also happened to me. I had 18,000 miles and the motor went bye-bye. As long as you keep the stock pulley you are ok. I went with the 2.93 lightning pulley which is about 4 psi more of boost. If you go into SVTPERFORMANCE there is a few that already have had this problem.

Also why is it in 03 they built over 13,000 but in 04 they only built over 6,000 and alot of them sat on the lots and the dealerships had a hell of a time getting rid of them.

Also note: It went in for 2 axle replacements, throw out bearing, new rack and pinion and then the motor. Then I sold it.
also I never ran any slicks or drag radials either.

Just keep watching they will keep having problems. Even some of the early models ligtnings are having problems with blowing out the spark plugs.

That's what they want you to think. Ford was just jealous because GM's Big-Body LT1 cars were beating up on all those slow 5.0s and LT1 F-bodies were just rapping them

I'm not flaming at all. I'm just laughing at a really factless comment you made.
