I'm well aware of what 03/04 Cobras can do. I love those cars. I'm also aware that if I had the coin to drop on an Eaton TVS 2300, with those mods on my LS1, I would hit 550-600+ wheel easily. Still an IRS car, and not too much heavier than a Cobra. (Curb weight 3855) But, I'm a broke college student playing the cards given to me. I have a basically free Eaton 112, and a free set of SLP long tube headers. Annnnnd I like my interior better.
