Your instincts for Mobil 1 0W40 European Formula are spot on. Defy 10w40 ain't a bad choice either if you're cheap.

M1 0w40 only has 1000 ppm of zddp.

VR-1 conventional and Syn are not true "racing only" oils... They surpass the requirements for your 1970s street engine. There is a racing only version, but I have never seen that one on the shelf.
I have used the Syn and conventional VR-1 in my motorcycles ( 100hp/liter ) on the street for up to 5000miles with excellent OA results.

He could always Red Line additive the ZDDP level upwards IF needed (one bottle would last a LONG time!).
