I read through several of the older ZDDP threads and then decided to take a fresh look at what is available today.

Throughout most of those threads I ran into two areas of concern for the Valvoline VR-1 20w50 that I use. Oil weight is too thick and there are none or not enough rust and corrosion inhibitors.

Then I finally found this at Lucas for their Hot Rod 10w40 packaged oil:

Available in convenient 5 quart bottles, the formulation is perfect for the Hot Rod and Classic Car crowd with an increased zinc value of 2100 PPM. Because many of these very special machines often spend long periods off the roads, a number of the components of the additive package used in Lucas' Marine oils to provide rust and corrosion protection have been included in its unique formula.

At $36 per 5qt jug I can order it at Summit or others with free shipping. Seems like this and a high quality filter would be best for my factory never been apart Pontiac 70k engine? Should I add some ZDDP to it or leave it be?

If you have a better and more cost effective way of getting this done please let me know.

Thoughts?
