What is the diameter of the clutch master cylinder? What is the pedal ratio? At what point in the pedal travel does the clutch engage?
I just went through the same thing, changed from a diaphragm clutch to a B&B 3-finger and the pedal pressure increased dramatically. Had to go to a smaller diameter MC and change the pedal ratio...ideal clutch pedal ratio is around 5-1.

The Problem I am having is a very very hard clutch to push in I am using the old style 3 finger pressure plate & a clutch I got from American Powertrain which hooks like crazy. Everything worked great and over the winter I did some work on the motor & other suspension up grades & I relocated the clutch master cylinder to the engine fire wall from under the dash on a bracket. I was wondering if it could be the old style pressure plate I have and I should i be using the newer style plate and before anyone ask I did bleed the lines and its a good stream of fluid & no air at all. 
The pressure plate load shouldn't be an issue, IMO it may be the type of master your using, and with your recent relocation you may have changed the pedal geometry?, or you may have shorten the travel of the master?
I run a 3 finger Sachs Borg/Beck 2800 lb 11" pressure plate with a Sach's Kelvar disc in front of a Keisler TKO600 5 spd, I using the Keisler/Wilwood .700 bore master and an FTE hyd throw out bearing, the master is mounted directly in the firewall hole intended for the stock 4spd pedal rod to Z bar application, the pushrod to activate the master is attached to the stock pivot point where the 4spd stock rod would attach, total pedal travel is 4 inches, total travel of the master is 1.400 inches....pedal effort is non-existent

I really think its my pressure plate and here is why.! My friend did his the same way and is running a dual disc clutch & a diaphram clutch and his pedal is way easier to push than mine.
