2003 Ford Mustang Mach 1 Premium Low Miles Great Condition!

The 2003 Mach 1 makes up for cubic inches with multivalve technology. It uses the 2001 SVT Mustang Cobra's 32-valve, 81-cu.-in. (4.6-liter) V-8. But if you look at the Mach 1's numbers — 305 bhp at 5800 rpm and 320 lb.-ft. of torque at 4200 rpm — you're bound to ask a big "what's up?" For the horsepower number is down from the Cobra's 320.

The reason is that Ford changed several engine pieces to give the Mach 1 better torque at lower engine speeds, t the sacrifice of peak horsepower. The biggest change is to the higher-flow cylinder heads, hich were fitted with intake cams from Ford's 5.4-liter V-8. Different exhaust cams were also added along with a new set of exhaust manifolds matched to the cylinder heads.

So while the horsepower number may not look as good as the Cobra's, he Mach 1 has gained 3 lb.-ft. of torque that peaks at a much lower 4000 rpm compared with 4750 for the 2001 Cobra. In other words, ord has just improved your chances at the highly coveted stoplight drag wars.
