my next build will be a 4door 63 valiant /6 too.
what year 4 door is your dart?
Rv cam and 4 bll intake and a new paint job.
and I like a four door A body, there are a few here.
here are the parts I have when I get the little A /6.
The before the intake was cleaned and powder coated by
Phoenix Specialty Coating and the the tail lights ready to put on
you can really make these four doors look sharp and add sway bars for some great handling and a good exhaust for a good sound.
What slant 6 do you have? 225, 198, or 170.?
The last picture is a car just like the one I will be doing.
