More of a result of pipe-dreaming than actual inside info, the 2010 Plymouth Road Runner Concept that’s featured in the August/September issue of Mopar Enthusiast magazine is based on the new Dodge Challenger using styling cues from the ’71-’72 model year Road Runners. The folks at Mopar Enthusiast beleive that if the car were to be produced today, it should be powered by a HEMI 5.7L V8 as standard with 6.1L and 7.0L V8 HEMIs being offered as optional equipment. -Continued Via: Autoblog.com , Source: Mopar Enthusiast
