70 340 Swinger-What's she worth?

I don't honestly know what to tell you on value, without standing in front of it and looking at the actual car. I will say, that if it's a rust-free car, and I was in the market, I'd be all over it. It looks like a fun ride. I'd clean it up a little, and rock it as is. Maybe slap a set of skinny CenterLines on the front, some bigger tires on the back, and a set of headers. Good Luck!
