It's also a matter of volume. The front calipers need a lot of brakefluid to move and MC's like the S-10 has that construction. The rearpart has a higher diameter then the frontpart.
One of the major reasons why so many goes with the S10 is its configuration of the lines. It is one of he few that has its lineoutlets to the left. That means that you can route your brakelines away from the engine. If the brakelines go to the right they will interfer with your engine.
The QTU S10 master cylinder has been a topic of conversation lately in that it has a difficult time moving enough volume without undue pedal pressure. The QTU design is very effiecien in a good power assist situation, not so good in a manual application. I would guess with vaccum assist it would be in the middle somewhere. Try it out and if not look into the hydraboost option.
Use the 98-up Fbody master cyl from Z-28, SS, or Trans Am models. They show up on Ebay all the time for around $35. As stated earlier...the S-10 master doesn't move quite enough volume for the C5 fronts and rears. I am using this exact setup with a hydroboost unit as well, couldn't be happier with it.
