Sox & Martin weren't the only drag racing team that received help from Chrysler. Not far from the Chrysler Engineering facilities, drag racer Ted Spehar "field tested" parts for the engineers that worked in the Chrysler Drag Racing R&D Group.

In 1971 Spehar built the "Motown Missile" Dodge Challenger. The car was so tricked out and well prepared that many competitors cried "foul" and assumed that the team was cheating! Spehar and his team would arrive at the track, unload the black and gold Challenger, make a qualifying run, and blow everyone into the weeds. Then, they'd take it easy till race time!

Once, just to keep everyone guessing, Ted attached clear plexiglass disks over the front wheels. The competition went nuts. They just KNEW it was something trick and probably illegal, when it was just plexiglass.

The ‘71 Motown Missile was at this point, more of a Super Stock or Modified Production car that what we usually think of as a Pro Stocker. Grumpy’s tube-frame Vega was still a year away.
