As another poster had stated I would use Mobil 1 full synthetic. For the 71 350 engine a 10-30 would work well. I would do a drain and fill with a less expensive synthetic and change it after 100 miles or less since it sounds as if the car is somewhat neglected. When you change it put in the good Mobil 1 with a Fram Ultra quality filter.

I don't know if you're still looking for recommendations, but I used and really like Drivens GP-1 racing oil. I was using the 15w40 in several flat tappet V8s. Just another option.
