You sure it was a hellcat?
A 392 car can be equipped to look VERY similar to an HC.... lighting package and all.
From a roll a stock 13/14 GT500 and a Hellcat is a driver's race. Take a lightly modded GT500 and you have an easy win over a stock Hellcat from a roll.
Had that been a 392, it would have been a distant memory in quick fashion.
