Thanks Dave,
I have that story from 1978 and used it to guild this attempt.
The stock version fell into that forgetable sea of cars from the time. The stock 2.6 liter, rear wheel drive, and mid 17 seconds track times did not make it one that most people recall. Front wheel drive was about to become all the rage and most Mopar fans thought putting the Challenger name on such a car should have been a crime.
Thanks for all the comments!
