for my 1967 dodge with 383 engine i want a oil with a good amount of zinc. i just read on a car forumn that rotella has the zddp reduced.i know you can use a zddp additive but would rather just use a oil with a good amount in it.

Rotella is still around 1200 I think, more than plenty, and it's available in 10w30 which I would think would work very well for your vehicle.
