RB,
The pic of your truck is fantastic! Thanks for sharing.

I do love that particular color!!!

You asked earlier "Are they still poured babbitt motors?" (about John's suggested use of a later 235).
Short answer (without getting into the weeds) is yes, you can choose a later "insert bearing" 235 or even a 261 (same basic block) that will easily fit your truck.
If you are interested in more info on this topic, post questions over in the
Engine Shop forum as that's the best place to have that conversation.

Same suggestion applies to when you want to discuss other items like "driveline", "electrical" and other such changes you may want to make to your truck.
Keep the pictures coming!
