Got Dart yes it may have a forged crank. Im not sure when the 318s started getting the cast crank.
I know 340s had forged threw most of 72.

Also all horse power ratings dropped in 72 becuase they lowered the compression.

not true at all. the hp didnt Change at all. they just went from measuring engine hp to rwhp. u can lose a good bit of hp thru your drivetrain
