Default Do I need a larger master cylinder?

My clutch is not fully disengaging. I've blead the system already, but no improvement.

I have a 3/4" bore master cylinder and a pull-type slave cylinder, the bore of which I have not checked yet.

I've run through catalogs and found that 3/4" for the master cylinder is pretty standard. Am I missing something here? I've adjusted everything for max-travel but there is still a bit of drag on the clutch. If it matters, it's a Ford Motorsports clutch between a 289 and a Tremec 3550, and in a stock Ford bellhousing with a stock Ford fork.

My first instinct was to figure the hydraulic displacements and just go with a larger master cylinder to move the slave cylinder a bit further. But the more I think about it, I feel that my FIRST step should really be to tap the vast knowlege of the Club Cobra crowd. What I NEED is for the slave cylinder to travel a bit further. Probably 1/4" would do it.

Help???
