Here's my take on this:
I've owned lots of Mopars of all types. Original hemi cars, superbirds, 440-6 cars, 318 cars, clones, survivors, etc.... and thru them all, the clone/modified cars did not feel any different to drive than the original #'s matching cars. When you are behind the steering wheel, you cant see the VIN # or the numbers on the block or the fender tag. I've been into mopars since i was 10 years old, owned my first one before i could legally drive. It's always been about making my car the best I could for myself, and having fun DRIVING it for me.
