Just to post back results, they were not good. The 1" bore master was still out of fluid at full stroke (pedal to the floor), even though a Wilwood tech assured me that 1" would supply plenty. In frustration, I swapped back to the original calipers, but did a full bleed after doing only one side. I had a pedal, but close to the floor. After swapping and bleeding both sides, I again had a good pedal. After all this d!cking around, the net change was from a 15/16" master to a 1" master, a lighter wallet, and a shelf full of wasted parts. I have not driven it yet, but I'm pretty sure the brakes will s%ck even worse than before...
