1969 318 bone stock 2 bbl with a new timing chain and water pump 79k miles. I was told by the 2nd owner that the engine and transmission was never taken out of the car.
Any quality 10W-30 oil that does contains ZDDP.
Valvoline VR-1 is good example, there are many others.
Dont waste your money on additives
Do spend your hard earned money on a good oil filter. I was in the engine industry for close to 40 years and always have used WIX filters. I like the internals of their filters and I have never seen a total failure. Dont trust the crap filters they sell at some big box store.
Good luck
