2003 Ford Mustang Mach 1 �€" 4.6L 32-Valve 281 DOHC V8, 5-Speed
Manual, Red over Black Leather Why This Car Is Special The 2003
Ford Mustang Mach 1 occupies a specific and well-earned place in
the SN95 Mustang story. Ford brought the Mach 1 name back after a
26-year absence, last seen on a 1979 model, and used the 2003 and
2004 model years to field what was effectively the most capable
naturally aspirated Mustang GT you could buy at the time �€" short
of the SVT Cobra. What separated the Mach 1 from a standard GT was
the engine. While the GT used the two-valve 4.6L, the Mach 1
received the 32-valve DOHC version of that same block �€" the same
basic architecture used in the SVT Cobra �€" rated at 305
horsepower and 320 lb-ft of torque. That engine, combined with the
Tremec T3650 5-speed manual transmission, gave the 2003 Mustang
Mach 1 a legitimate performance identity that the GT simply
couldn't match. Ford built the Mach 1 for only two model years,
2003 and 2004, with total production hovering around 9,000 units
for the 2003 model year. That's a low number by Mustang standards,
and the combination of a specific engine, specific trim level, and
a two-year production window means these cars are increasingly
difficult to find in honest, unmodified condition. This example
presents in its factory red exterior with black leather interior,
carries the Tremec 5-speed, and shows a clean floor pan and frame
rails with no visible rust �€" important details on any SN95 that's
spent time in a northern climate, though this one appears to have
been spared that abuse. Features List - 4.6L 32-Valve DOHC 281 V8

this 2003 Ford Mustang Mach 1 is the 4.6L 32-valve DOHC V8, the
same family of engine Ford used in the Lincoln Mark VIII and the
SVT Cobra. In the Mach 1, it was rated at 305 horsepower and 320
lb-ft of torque in stock form �€" a meaningful step above the
260-horsepower two-valve GT engine. The DOHC heads flow
considerably better than the two-valve units, and the engine
responds well to bolt-on modifications if a future owner chooses to
go that direction, though this one appears to be in stock
configuration. The engine bay is clean with no visible leaks, and
the V8 32-valve badging on the valve cover is present and correct.
Backing the engine is the Tremec T3650 5-speed manual transmission,
which Ford specified for the Mach 1 to handle the torque load of
the DOHC engine. The T3650 is a well-regarded unit in the Mustang
community, more robust than the T45 it replaced. The three-pedal
configuration is intact, with aluminum sport pedals visible in the
photos. The shifter uses a chrome/polished knob, which is a Mach
1-specific detail. The underside of this car tells an important
part of its story. The floor pan is solid with no visible rust. The
frame rails are clean. The rear sway bar is in place, which is part
of the Mach 1's suspension package that gave it improved cornering
behavior over the base GT. The dual exhaust runs from the DOHC
engine to polished tips at the rear. The suspension components and
exhaust routing visible in the undercarriage photos show a car that
has not been significantly modified or poorly repaired. Interior
