2003 Cobra
My buddy had an 03 Cobra, it was quick stock with a CAI and catback. But after a few mods - Kooks LT's, Apten ported blower with a 2.73 pulley and bigger TB, it laid down 519rwhp on a mustang dyno 
Talk about a scarey ride! Man did it kick you back in the seat 
I would go with the cobra.

LS1's are not as fast as 4.6 blown engines.....BUT....they will last twice as long.....4.6's have cooling problems when run for extended time....this is from an SVT Mechanic.... 
All depends on the price, I personally would prefer the LT1 since you don't see them as often, they look better to me (not saying the cobra isn't dam sexy) and with the 13K+ difference in price, you can strap on your own blower on top of a stroked, fully forged bottom end and be making way more power, and then be putting it down better then the IRS in the Cobra, not to mention they have a good 500lbs on these cars. All depends on price and whether you like to let everyone know your fast or be the sneaky, underdog type. But if it were me, I would go for the T/A, I have a 97 WS7 and I don't think I would trade my car for a Cobra if someone tried to offer it to me as a straight up trade, thats just the way i feel, but I'm a pretty die hard LT1 fan

sorry im goin with the cobra on this one. ive ridin in one and i think pretty much anyone will tell you to get it over a stock ws6. whats stupid is the people who get on here and say well the ws6 have this done to it and this. that wasnt the question it was how much faster and which would be better. ws6 youre lookin at roughly low 13s, with the cobra youre lookin at about high 12s.
and for the people who are saying that 13k can be spent better on a LT1 this is probably a matter of financing a car. im pretty sure summit doesnt finance cat back exhaust, cai, or ported heads.

Cobra's are sweet but how many lt1 Ws.6's do u see rolling down the road? I know that theirs not many ford's I'd trade my 96' SS for. It would have to be a very clean (03-04)Cobra for a good deal then i might.

With equal drivers the Cobra will come out on top, but not by bus lengths, like a car or 2. My car put down 316/341 with a lid, !cats, cut out, and 309/330 ish stock so that is where the 40rwhp difference comes in. For the guy posting, the price difference is about 13k between the 2 if you have that much of difference why are you even considering the 2 and go with the Cobra!
Course once you crack open the motor, anything is possible.
SDM1234:
Both LT1s and LS1s were underrated. Real ratings would be closer to 305 fwhp for the LT1, and closer to 350 fwhp for the LS1.
In your shoes I'd probably get the Cobra. It's not worth it to buy an LS1 over an LT1 due to cost, but I'd buy a Cobra over an LT1 definetly. you can make 500+ hp on a stock blower

My brother in law has a 2003 Cobra and I have driven it a few times. It is a nice car however, it does not feel like it is "ALL THAT" But it will spank a stock LT1, LS1 it probably will eat an LS2 however, an LS6 is a different animal story! However, I have not driven a stock LT1 in years.
For the money it costs for the Cobra I would get a C5 Fixed Roof Coupe and have money left over for mods.

I have never seen a guy with an '03 Cobra break 12.9. Do you know why? Because those things are damn hard to launch. They are mid 12 second cars stock, but it takes a good driver to get those things into that range.

I have gone 12.82 in a bone stock LS1. 12.70 in a 03 to 04 is not getting rapped beat yes. Their potential is AWESOME!!!
On AVERAGE....please read...on AVERAGE....The Cobras are a good .600-.700 maybe even better, faster than LS1's. Bone stock for both.
I don't think that is the record and that was done at Bremerton raceway with an *** ton of people watching. I will have to dig out my time slips. I have them somewhere in this mess of a house.
Ask some of the people in the northwest forum, they were there. Of course if you were not there it is all heresey. So you don't have to believe and I will not argue about it. Have no reason to lie about it. Hell my Crapper 00 WS6 would go 13.20 to 13.30 bone stock all day long.
Having said all that the Cobra is bad ***. A few small mods and you are making carzy power...If that is what you want I say go for it. I just don't do Fords.
