bleed the master cylinder, and then all the lines starting with the furthest wheel from the MC and working inward.

 

Was this a new master cylinder? It should of came with a kit to bleed it before you install it as I remembered mine came with one when I installed it on my old fox body. I had to do this http://www.superchevy.com/technical/.../0509sc_bench/. After that I would bleed the brakes like mentioned above.
