Thanks all!
FWIW, besides the master cylinder, there are a few cosmetic under-hood items that I'd like to address. Right now it's about making sure everything is working reliably (no leaks, loose stuff, maintaining clearance from moving parts, etc.).
The ProCharger pulley actually came with a spacer, although I swear there's nothing in their instructions about it. The belt rides just up to the edge of the blower pulley (but not past it), and that's where the idler pulley keeps it. It's a bit of a PITA to pull the pulley's hub, so this being something of a cosmetic fix, it may wait until another day.
The cage is not NHRA-certified, although I should be OK at my track at 10 seconds and slower. It came from Big Nana's truck last summer. He had it built to pass tech for his speed record runs. I also bought the seat, harness, and chute from him. I really appreciate the fact that he stepped up and had all of that fabbed, but I'm certainly sorry to see his truck go. Funny thing is that even at 6'6", I can just see over the dash. The seat had to be set low enough (for both of us) to keep the helmet below the cage's halo.
More to follow.
