The car for today is M2's 1970 Ford Mustang Boss 428 SCJ.

the 428 SCJ (Super Cobra Jet) was first introduced during the 1969 model year. Mustang buyers who ordered either of the optional 3.91:1 or 4.30:1 rear end gear ratios got much more. Ordering either of these axles automatically triggered a few other upgrades as well, including the 428 Super Cobra Jet engine, an external oil cooler mounted in front of the radiator, and relocation of the driver's side horn to the passenger side of the radiator core support to make room for the oil cooler. Starting in February 1969 this complete package could be ordered as the "Drag Pack" option. Note that it was not possible to order an SCJ engine by itself -- the only way to get your hands on an SCJ in a Mustang was to order the optional 3.91:1 or 4.30:1 rear end gear ratios.

The strength of the Super Cobra Jet engine was based on more durable internals, including the crank, rods, pistons, flywheel / flexplate, and harmonic balancer. These special components were designed to withstand the higher RPM requirements of drag racing. For example, the SCJ used race proven 427 "LeMans" capscrew connecting rods, whereas the standard CJ rod used a more common press fit bolt and nut to retain the rod cap. The SCJ timing pointer is slightly longer to clear the larger harmonic balancer.

Connecting rod research seems to indicate that CJs used a variety of common high end FE rods, with the C7AE-B rod being fairly common. Others have reported finding C6AE-C, C6AE-D, and C6AE-F rods in what they believe to be original engines. There is also reference to a C9AE-C rod being used, but nobody has been able to confirm an installation. SCJs seem to use the C6AE-E rod most frequently.

A common misconception is that SCJs were originally equipped with forged pistons and CJs were had cast pistons. Ford's "Muscle Parts Description and Interchange" book, a supplement to the original "Muscle Parts" catalog that was published in July 1970, clearly states that "all 428 engines use "dished" cast aluminum pistons with two sets of eyebrows cast so they can be used in right or left bank."

M2 used their existing '70 Mustang casting to turn out this monster of a Mustang, the Super Cobra Jet. Jeweled headlights, rubber tires and all metal construction with an easily removable base state the case for M2. The extra detailing on air intake and floor shifter offer details not usually found on small scale diecast.
