Motor oil for an original motor?

Hello all!
I am trying to figure out what type oil would be best for a unrestored DZ 302 engine. The engine just turned 78k miles. Right now I am using Shell Rotella SAE 30. I have read on some other post that the zinc is needed. Maybe I am using the correct brand of oil but what about the weight? I obviously want what is best for a old engine that has not been over hauled.
The car is driven by the way.....

Also, how about trans an rearend fluid? What do you recommend?

Thanks for the help!!!!!!!!!
