- '01/'09/'19 Bullitt, '90 GT, '00 Corvette FRC
From one of the development engineers I interviewed for my first Mustang book (Engineer + Enthusiast = Excitement: Building the 2001 Bullitt and 2003-04 Mach 1 Mustangs) -That said the story that the 2003 mach1 engine wasn't the rejected early 2002/2003 engine and was designed for the mach1 all along still never added up to me. I always kind of felt like the engine was already mostly designed and just found itself as a thing that Ford could drop into the Mach1 and Marauder recoupe production costs. Otherwise it would have only been used in the Lincoln SUV's. I'm now wondering if in 2003 the Mach1 was planned to be little more than just a BULLITT with a tweaked intake tube for the shaker, maybe just 5-10 more HP but the extra engine just fell into their laps so they used it. With no engine falling in their laps this time they just used the Bullitt engine. (Which as I've said before its always felt to me like the GT350 wasn't supposed to be going on so long and was supposed to be replaced by a BOSS until the Mach1/E marketing fuck up and a possible GT500 delay happened.)
Ford leveraged the update happening to the DOHC 4.6L V8 across the Mustang, Maurader, and Aviator - that was a deliberate choice. What's unique to the Mach, of course, is the shaker scoop induction. The Mach 1 program specs were to have noticeable power difference different than the Bullitt of the time. The development team was planning to leverage the non-supercharged Cobra engine because the Terminator supercharged engine was going to replace it, independent of the other updates.
It was good timing that the engine update across lines was going on then.
In other words, the stars aligned
