Hello folks '67 Barracuda

Welcome. Has the engine been sitting for 20 years since rebuild. If so it may need rebuild again. I know the 273 was phased out through Dodge builds in 68. I think I remember reading that the 273 ended in 67 for Plymouth builds. 68 Plymouth would have a steel crank 318.
With a decent paint job it might be worth 7 to 8 K but not in primer.
Just my opinion, Good luck
