Thanks for the input people, keep em coming.
As some of you know, I've owned a lot of Mopars thru the years, some of them I'd love to have back...but with each sale I've moved on to another great Mopar, so selling and moving on is not something I'm adverse to. That said, 71 cudas are hard to find for a good $$ number nowadays, and while i have a nice bit of $$ in this car, it's worth way more than i have in it. My biggest problem would be the time investment, I know it would take at least a year to take the car down and get it back together the way I'd want it. I can see the value in getting a 440-6 back in the car, but that would require the change out of the exhaust system and building a new motor, again more time invested, not to mention the $$.
I'm just considering my options here, and i appreciate your views and opinions.
