If you want a good additive for the engine... look at Speciality Formulations additives for older engines from MolaKule.
That engine should live well on a good SL oil, but with the above additive....live longer.
My old 72 F350 HUGE BLOCK lasted forever, I never treated it as I would today. Seems I abused it and drove 1/1.5k miles a week back then and hated brake changes more than a root canal. But I changed oil religously every 3-4-5k Miles. That motor was tuff, and I'd never advise abusing ANY motor like I did it. I NEVERE added a drop of oil between my extended oil changes (see abuse) but she ran and ran. 10 MPG was pretty much the norm, but I couldn't brake it. I
hauled huge trailors of wood and/or rock nearly every week. I loved laying rock, I abused that truck with no conscience. I ran cheap oil, whatever, Fram filters, cheapest gas, and torqued her many times each day. One day I got gas as a truck unloaded (no filter on fuel), and she started spitting and 4mpg, I'd fouled a valve.
Had heads pulled, seats cleaned and drove/abused her for another 100-150k miles.
These engines were thirsty, but dependable. Built for that purpose. 327,000 miles of terrible abuse, cheap oil changed many miles too late. Carrying way too much weight everyday, pulling way too many trucks outa mud, abused (had the 4x granny tranny), she was built better than a tank. I really miss her (except she drove like a TRUCK). I love my truck and my porsche, but they'd fall short of abuse your truck could handle. HTH, That is a working truck, not like ours today. I doubt you could EVER wear it out with minimal repairs. At 300,000 miles
