Hell, new to this site, I have owned my stang since 06 and just blew my 4th stock GT shortblock. i'm giving up on the 2v, Go big or go home, right? I want to get a 4v Navigator motor in. Does anyone know if the shelby lower intake manifold bolts up? that way I can redrill for my stock series 3 blower? Also will I have hood clearance issues? and can my stock wiring be used with slight modification. I heard the Gt ECU can be flashed with a SCT programmer of accomodate the extra dissplacment and 4v heads. Long term goal is a 2010 super cobra jet engine with a hellion twin turbo kit for compound boost and a fr500 tranny
