I believe that there was a posting done on the other Cobra related site. If so the the Webers in that photo date sometime after 1969.
I have an early "XE" part numbered Indy quad cam crank in my 5-bolt 289 hipo engine, although the crank was originally set up for a dry sump oiling system this one was modified for the wet sump application and slightly stroked (.189"), all the mods were done in period. I have seen a bare cast iron version of the Indy block with the
oil pump mountings built into the four bolt main caps, very interesting piece.
