Can I guess that you're using power brakes? From what I've read on here and elsewhere, using a larger bore increases pedal effort. I've read a few threads on here where people use either a 1" or 15/16" diameter MC...it increases pedal travel, but from the people who've done it, the feel is better and effort is reduced...but-that was with stock size brakes. I'll be watching this thread since you're using a different combo with large drums and the Wilwood front kit. You might want to search through the threads and see what others have used/what works together.
