a couple years ago, the only time I have been to the race track, there was a Challenger with a Hemi in it, I don't remember if it was a 5.7 or 6.1, but I was beating it on the 1/8 mile by about 1 second. my grand prix was running what a stock grand prix should run on the 1/8. it was like 2013 or 2014, and the Challenger was a 2011 or 2012.
