Looking for advice. Want to build a Duster to run on a budget.

that barracuda is pretty nice, there's one around me for 3k with a 273. the guy has been flaking on me but he's a friend of a friend and its not listed anywhere so eventually I'll look at it.
If you’re serious there is a much nicer one near me that’s in better shape and probably cheaper. Next time I drive past it I’ll get some pics.
