Mopar fans Don and Liz Crockett toured in their emerald-pearl metallic'36 Plymouth four-door. The owner-built sedan uses an '04 5.7 Hemi and five-speed automatic. Front suspension is Mustang II, and a Corvette IRS resides in back. Inside is a Tea's front seat with matching upholstery throughout, while a Vintage Air heat and cool unit controls the climate. Along with performance that is superior to the 340 it replaced, the new Hemi has clicked off as many as 33 miles on a gallon of gas.
