Another non-Mach 1 addition is the car's transmission. As mentioned, the couple's project Cobra donated this part of this equation as well, but it's not a run-of-the-mill TR3650-it's a '00 Cobra R T56. The Cobra had the six-speed and supporting gear, but Jeff went a step further by installing a 26-spline input shaft with a RAM HDT clutch before mating it to the fresh Four-Valve. He left the Mach's 8.8 rearend as is, so that's the last stock piece to the puzzle.

OK, so many of you reading this may be scratching your head trying to figure out Jeff's method to building this car. Jeff built the car for the street and open-track action. He wanted a lightweight '03 Cobra. This is his hybrid version. Jeff blended a Twin-Screw Cobra with an aluminum block, a built six-speed transmission, a solid axle, and slightly used Maximum Motorsports suspension additions.

Jeff figures he saved probably $10K by purchasing stuff used, or through wheelin' and dealin'. We'd take Jeff's thrifty hybrid over a Prius any day of the week. Sudden acceleration would always be commanded by our right foot.
