Zinc, not zink. And flat tappet engines once broken in do not require high levels of ZDDP.

5W-30 with what API specification was given?

API SF used to be a zinc level of 1000-1400 ppm, not all SF oils had the maximum of course.

Mobil 1 0W-40 FS is about 1100 ppm zinc and would work well in that engine. Another choice might be Mobil 1 Turbo Diesel Truck which is 1300 ppm. But the 0W-40 FS is pretty cheap at Walmart and carries a bunch of stringent approvals. Castrol 0W-40 is equivalent.

I've had the same car as yours for 30 years and I have used various brands of 10-30 to 100k miles with no issues other than that my 2.8 is an oil leaker these days.

There are thousands, if not millions, of cars still on the road with non-roller camshafts. The Jeep Cherokee comes to mind. Unless you are running some kind of high performance camshaft in that Fiero, you really don't need a special oil. Pretty much any 5/10w-30 will get the job done.
