hey nice car there. Make sure you get ALL the rust. There is a really good article in mopar muscle magazine
here about removing rust and some of the areas where you might not expect to find it. If your spending money, it may be worth looking into. I have a 3rd gen as well (73) andi have rust behind the door on the inside of the car. You cant see it from the outside, i found it when i had the interior torn out and was cleaning up and adjusting the rear 1/4 window. Im going to cut off the outside and fix it. Just make sure you get it all

or it will haunt you.
and it looks like a 360. I am upgrading my engine to a big block, so I will have an intake and carburator for sale for a small block mopar. Its a 4bbl edelbrock carb with edelbrock intake. If your interested then let me know.
