1976 dart slant 6

Hey all. I'm new here and I just got a 76 dart sport that I'm thinking of putting a slant six with a turbo into her. Do you know what year motors are the best for my application? I'm looking into local salvage yard and the internet for my purchase. Thank you for your time.

Okay I was just looking at oil pans. Can I use any /6 from 67 to 76?
