Paws72, as long as it has a fairly calm cam I'd use Valvoline MaxLife 10w30/40 with no additives and have no worries. I run it in my Suburban's flat-tappet, carbureted 350 ("broomstick" truck cam - only put about 10K on it so far), it's the oil my dad used in his '97 Suburban from 170K to-date (415K and counting) and I've seen it cut consumption roughly in half in a Dodge and Buick 3.8L V6, both with just under 200K at the time.
