Brakes have me baffled!

I can't figure out what's up with my brakes.

Here's the background. The brakes in the car have always sucked. Until recently I had a stock cast iron master cylinder and drums all around. I upgraded the front to Wilwood discs, replaced the master cylinder with an aluminum unit I bought from GregZ @ MagnumHP a while ago, replaced both real wheel cylinders, replaced the line lock with a brane new unit and replaced all of the lines between the master, line lock and distribution block.

I've adjusted the rear brakes, bled them over and over, bled the fronts, and bled the master before I installed it. I replaced the line lock today, and when I did I re-bled the fronts. Nothing but pure fluid coming out, no air.

When I step on the pedal, it has about 3 inches of travel before I get anything. When I do get something, I hear and feel a "clunk" like I've hit something solid. And it doesn't stop at all while it's within that 3 inches. Once I get past that point, I have only about 1 inch of travel before I can't move it anymore, but it's not to the floor. In that 1 inch, I've got a little brakes or more brakes, but not enough to lock up the wheels. If I go in reverse about 30 MPH and jam on the pedal it'll lock up the wheels, but I don't think it'll do it going forward.

If I pump it up 4 or 5 times it'll get a little firmer - but not much. It'll give me about 1/2 more travel before I hit that solid stop. After I let off of it (after pumping) I hear the sound of fluid moving around, but I can't tell where it's coming from, but it's somewhere in the area of the master cylinder, the lines to/from it or the line lock.

Any ideas? Suggestions?
