My engine builder used Lucas 30W break-in oil.  They also pre-filled the 
block at the oil pressure line port.

This rebuild includes minor mods including a Denis Welch DSW-8 cam and bucket followers (with pockets in the block) and high capacity oil pump. This cam is drilled to provide oil to each lobe. The engine was also balanced. Once broken in I plan to run 20W-50 Valvoline racing full synthetic with ZDDP, which I’ve run in my XJ6 since 2012 or so.
