I have seen a couple up on the different lists that float around but I am having a hard time telling exactly who has the fastest 03/04 cobra. Still on the stock block. No Cams/pistons/heads. Still running the Manual transmission and still rocking the IRS out back. Non turbo. I don't care if it is a ported eaton or a Whipple or a Kenne Bell. Anyone who knows who the top ones are let me know! Thanks!
