V10 Challenger?
 

It has been a while since i have been on here so i appologize ahead of time if this topic has been kicked around too much in the past.... but with the sunsetting on the 600 hp V10 viper i have not heard anything about the reality of actual production of the concept challenger that had the V10 in it...any news?

The V-10 was only a concept. No plans that I've heard to stuff it in a production Challenger. Look for the 6.4 late in the 2010 model run.
