A-Body Autocross?

Hey guys, I haven't posted on here in forever mainly because I haven't had time to work on my Mopar. My 1970 Duster 340 has been patiently waiting for a restore for many many years and I need to start considering it or sell it. But recently I've had a bit of a bug in my head.

Last year I raced my 07' Mustang in autocross and had a lot of fun but the Mustang was too big and would need some work to become competitive. I really don't want to turn it into an autocross car but then I got the idea to do it to my Duster. I realize it would be one hell of a project but I also think to would be fun and challenging.

What do you guys think, am I out of my mind? Have you heard of any successful examples of this? I've also considered the idea of just swapping the engine into an a-body Barracuda and trying it instead of the Duster.
