Rough idle after oil change, need help just took delivery of my 76 turbo

I just took delivery of a 76 turbo 47k miles, had a full top end rebuil in 2000 with 40K miles, car needed an oil change, so i read nearly half of the 40+ page thread and decided i didnt want a synthetic oil since it has only run conventional. Anyways, i found a border line oil at autozone with an sl rating that should have enough zn and phos. i put in a 20w50 weight with a new filter. Now the car runs extremely rough at idle until temp comes up and it smoothens up. I looked at the manual and it says that it takes 10.6 quarts and prefers to run sae 30. I am going to change it tomorrow again but need recs from what i can pick up locally or shoudl i just bite the bullet and wait for some swepco. thanks.
