THREE MORE 20W/50 CONVENTIONAL MOTOR OILS WITH .119 ZDDP LEVELS AS OF 02/2008:

Kendall GT-1 High Performance motor oil
76 High Performance motor oil
Phillips 66 TropArtic Racing motor oil

All have Product Data Sheets published in February 2008 by Conoco-Phillips listing both the zinc and phosphorus content with specific recommendations for flat tappet camshaft engines. C-P says the three oils are produced at the same blending plants. I prefer Kendall as my brand from the 70's, but it and the others can be hard to find.
