Curious

What did it get swapped into and where did the 11.20s come from?
Sorry - I re-read and saw the mid to high 12s testing which IMO is about right. Anything is possible - I'm sure a Hellcat swap, or GEN3 with a turbo and modern transmission could do it. But it's really big money and you'll get more looks with a slant 6 turbo in the same muscle car chassis at a cruise or car show.
Old cars vs new cars is foolish IMO. When a new domestic car is 40-50 years old, then you'll be able to get the true value and performance of it. When they are new, they are just plain old traffic. I don't care how fast it goes.
Stop asking questions and go do it.
