I am currently building a 4.6 teksed block cobra with 9.1 compression .40 over cp pistons. I am going to be pushing 15 pds of boost either thru procharger or turbo setup. I am running 04 cobra heads with 98 cams with 04 mach 1 intake. What would be best for a flywheel stock or exedy lightweight? What is the best fuel rail system that is recommended for this setup that I am doing? How do you feel about the 6 puck clutch vs. the plain circle disked clutch?
