1970 dart for sale big block $8500 firm
That is a nice car you have and the price looks reasonable. But more info is needed. What engine? You say big block. Is that a 383, 440, 400? and all the other questions mrtires24 asked.
If you want some one to buy it. those are things you need to know and post. No one on here is going to go to the truble of looking at the car if you don't post this stuff up.
I am not attacking you. Just trying to help. Good luck with your sale.
