I would use Mobil 1 0w40 or Mobil 1 High Milage. Their racing oils are excellent, but expensive and hard to find.
Rotella or Valvoline VR1 Racing oil is a good option too.
It's a roller motor. I would be extremely surprised if the engine needed higher levels of ZDDP, as Callaway would have adequately tested the engine under the harshest of conditions before making their recommendation (which, yes, I know, mirrors GM's, but anyway).
GM uses M1 0w-40 in their race program Corvette's, which likely have even higher power density.
M1 0W-40 is definitely easy to get and likely adequate. If I was spending the day at the track I'd consider Z-Rod or Dominator by Amsoil as good choices.
Note that in an entire day of lapping Homestead with 300 degree oil temps and M1 0W-40 in the sump my analysis' were excellent, it's a better oil than many know.
