Looking into rebuilding my 2003 cobra started with a slight tapping in the head that would come and go bought the car knowing it and was planning on rebuilding it anyways still don’t know what the issue was that caused it but it ended up melting a piston my guess is maybe a loose thrist pin there’s no way of telling right now with it still closed up but anyways just looking for what a good reliable setup would be to make 800-1000 hp open to any suggestions have pictures of previous build and melted piston if you’d like to take a look
