Call it a fantasy, but I am looking to have an engine built to put in to my Cobra... Original has 200,000 on it and I know it won't hold up to what I want to put it through. I am looking to build a very, very powerful car and wanted to see if anyone here has any experience with a good engine builder. I want to stick with a 4V DOHC modular... What I am interested to find out is what is a good way to go? I am looking to go with an aluminum block I am sure, actually looking at a Sean Hyland Race shortblock they say it will handle 1600HP. Does anyone have any experience with SHM products? Another question is what is better for performance the FR500 heads or stock 03/04 Cobra heads, or is there another option? I want to run the Hellion Hellraiser Twin Turbo system and I am already looking at the new Aeromotive Eliminator Stealth System with the sumped tank and a Sullivan intake. Any advice as far as ignition system? Does anyone have experience with the F.A.S.T. engine management system? I understand that this ECU is able to control better injectors.... Is there anything I am forgetting?
