Any FI car has a huge advantage over a NA - those motors are designed to handle boost so modding them is very easy and effective.
Beating a stock 03 is doable with a decent HC lt1.

See the latest issue in a mag with a 04 Cobra, Lightning lower pulley swap, cai and slicks...that being all that was done running 11.6's@119...
Re: How to beat '03 Cobra building on my mods
HP TV did some dyno runs with one with a Pulley to up the boost and a hypertech programmer and it put down 427rwhp. I thought that was pretty impressive.
I don't think a H/C LT1 will hang with that but with a 75 shot it should be able to beat it.
I've seen some of the 600rwhp Dyno sheets with the Kenne Bell Super chargers on them and the dyno numbers are impressive but I've never seen one run at the track. I think a lot of those guys are dyno queens and I have seen videos of those engine letting go at around the 650rwhp mark

LT1s like boost too...

There's a lot more. Cobras are nice rides, but for the money you can build an LT1 to make a lot more power and customize the car however you want.
Growing up around turbo buicks most of my life makes me wonder why the f-body crowd hasn't realized the power and potential in turbos until just recently.

Re: How to beat '03 Cobra building on my mods
This whole it costs less to do that is rather wrong.
How much to buy a new, fully loaded LT1 when brand new and then get it to make the power these Cobra's are.
You can get new Cobra's for $27K, but $7K in it and make 600+ rwhp on pump gas.
It is all relative...comparing 10 year old cars that now cost what 10 year old cars to a new car is not apples and apples.
Why buy an LT1 when you can buy 5.0? Why buy a 5.0 when you can buy a old SBC setup?

I see your point and ultimately it is ALL relative.
Re: How to beat '03 Cobra building on my mods
I don't see any reason why a modded all motor LT1 couldn't hang with or beat a 03 Cobra. Dyno numbers really don't mean ****, so that shouldn't really come into play. I watched my buddies bolt on Formula (it's an LS1 car) that put 370 at the wheels put about 6 cars on a stock 03 Cobra. He then raced another 03 with all the boltons and the smallest pulley you can put on the stock blower. The Cobra was making over 460 at the wheels and they were side by side winding out 4th.
