Should I buy This DEMON?

Hey guys new to Mopar stuff but always loved the look of the a-bodies. I always wanted a demon but I never could find one that wasn't fully decked out. This one is in my price range for a project car but im not sure if i should hold out for a 340 car. this one came as a slant 6 but the owner upgraded to v8 hanged k frame. Disc brakes in front

here are the spec in his add

318 bored 30 over flat top pistons comp cam, flow tech headers2 1/2" lots of spare parts for car. Needs trunk panel and tail light panel.Sand blasted the rear axle and painted it with a industrial grade primer 8 1/4 rear axle
Newer parts on car ,headers, shocks,track bars. U bolts comes with spare motor tranny and doors and spare window trim.

Have other parts for sale but are extra $ new in box still
Full msd ignition,coil,distributer,wires
New edel 650 carb chrome valve covers
Auto meter rpm tach

Im not sure what to think of the car always wanted a demon and maybe should jump on this or should i wait and try to find the one i always wanted?
