Cam selection help please

I was wrong about which cam was in Charles' rat rod. It's this one:

But, the two cams are very similar duration wise and will sound very close. That 275 extreme high lift I linked to first though will make more power. If you're still interested, I'll get a video. They'll sound very close.
