I have finally blown a head gasket in my 2003 mustang GT after 217,000 wonderful miles. She's been really good to me, but the TX heat finally got to her. I have a a** load of bolt on's, and I was just about to rebuild the rear to handle 600HP, but that's been changed to a crate motor for now. I have a six speed cobra trans in already. I'm wondering if i should buy a cobra crate long block, which I will have to purchase an intake for. Does anyone on here have a Eaton set up willing to sell? If not can anyone point me to a parts list so I can accumulate the parts needed to do the Eaton supercharger add on. I'm also open to any other suggestions or routes to go. Feel free to comment. At this time the engine is all stock, most of my bolt ons were for suspension and the such except the trans. The syncros were going out on my factory 5 speed, so I went back with the 6 speed. You can see how i'm going about this. When i'm done she'll be a gem again. Thanks for your time and input.
