The silver car you see in the video is Ralph's Cobra Jet. Both cars were started in January. Ralph's car was completed in April. Jimmy's was also pretty much done then except for the Super Stock engine. Jimmy's Cobra Jet is now set up as a Super Stocker.
MPR did a four link, but left the tubs and stock suspension mount points in it. The car be easily put back into Stock. Besides the time lapse video I also have some construction photos on my website at
