I felt like telling alittle bit about what I drive. My current car is a 2003 MACh1 Mustang. For those of you that don't know, yes, they did make MACh1's in 2003, and 2004 as a special model, as a tribute to those of the 60's and 70's.
The engine is a Modular 281 Cubic Inch four valve aluminum V8. It was rated at 305 hp/ 320 lb/ft. of torque at the flywheel, although DYNO tests reveal that it is under rated, and on average makes around 270 hp, 290 lb/ft at the wheels. (Mind you wheel horsepower is always lower due to the parasitic loss of the rotating assembly inbetween) You generaly lose around 15% of power from the flywheel to the drive wheels, while as these numbers are closer to a 10% loss, wich makes quite a bit of difference, and theirfor is under rated.
The engine is simmilar to that of the 2003/04 Mustang Cobra's Supercharged Modular 281 Ci four valve cast iron V8, and because they were made in the same year, they are always compared. However it's actually closer related to that of the 1998 Cobra engine, with the aluminum block and pistons, while as the 03/04 Cobra have cast Iron components.
What this means is a lighter engine weight, but Aluminum has a much lower point of temperature that it begins to warp, and can't handle the same amount of power as the Cobra's Cast Iron block.
The MACh1 is like a step up from the GT, bridging the gap between the GT, and Cobra. They only produced around 16,000 of them in the two years that they were made. But MANY more in the sixties and seventies.

Some specs about my personal MACh1:
Color and Options: Dark shadow grey, Interior Upgrade including Retro Comfort weave seats, 6 disk CD changer, 6 way electric adjustable drivers side seat, 4 way manual adjustable passenger seat. Miscilanious brushed aluminum interior dress components; all added aftermarket. (sterio face plate, A/C Face plate and knobs, cruise controll plates, etc...)
Exterior visual modifications: Vynil striping kit (although they come stock with a hood stripe, I have added to that), Brushed Aluminum upper and lower grill component insert, blacked out tail lights, chrome gas door, American Eagle 5 Spoke stars, Hood pin kit. The shaker system is stock from factory, but looks bitchin' and had to be mentioned.
Modifications: CAI, Bassani longtube headers to O/R X pipe, 3.73 gear, 10.5 in' Mickey Thomson street E.T.'s on the back, steeda tri-axe shifter with B&M T-handle knob, diablo sport tune.
Numbers: 12.5 in the quarter at 109 mph on conservative tune, and pump gas.
Total money invested: $19,200. (Car itself $18,000)
Current DYNO numbers: Unknown

Any questions would be appreciated as comments.

if the link is being stupid, it's because it's broken and you need to remove the space between the 4 and the 3.
