FYI, Amsoil also makes two high ZDDP oils in the weight range originally 
specified for the Corvair:

1) Type HDD 5W-30 Diesel oil - API CI-4+/CF/CF-2/SL
http://www.amsoil.com/storefront/hdd.aspx

2) Type ACD 10W-30/SAE 30 Diesel oil - API CI-4+/CF/CF-2/SL
http://www.amsoil.com/storefront/acd.aspx

Both of these contain 1267ppm ZDDP. Note also that they are API SL rated 
for use in gasoline engines. Please contact me off list if you would like 
more information.
