What's it worth?

Well, my wife isn't in a big rush for hers and said she'd rather I get mine done first so hers would be sittin awhile. Right now my 318 duster isn't much farther along than the 340 car. My plans are/were to get the 318 running and unless I can find an 833 for cheap it'll probably get backed by an ax15 from a dakota as the trans tunnel is already hacked up. I'll get the car running, driving and stopping good then focus on body and interior. Once it's all said and done I'd like to put a 340+6 or 360+6 in it. Now if I got the 340 car I'd swap most of the "340" parts over to it and probably just run the 318 and a 904 in it till I get a 340.

Now that all being said, I noticed some of y'all asked about the paint color.. If I don't paint it the original color, the interior won't be original color and drivetrain won't be original would it be worth it? I'm not planning on ever selling the car but if I would what would a car like that be worth? Basically, what would the car be worth if it were set up like the pics below but was built with the 340s shell and fender tag compared to using the 318 car with no fender tag?
