i have a 1977 with oil filter cooler lines.
Is that from factory or did they change the engine on this?

That was a factory option to the best of my knowledge. Probably part of the trailering special package, but not 100 percent on that.

I'm curious because my co-workers are saying they didn't have oil cooler lines in 77

You and your coworker are right. Oil coolers were an option, not standard equipment. Seemingly identical trucks could be different based on with/without an oil cooler if one was not optioned differently.
