Ive done everything...could this be the problem. Since my heads/cam have been installed Ive be having trouble shifting( pedal sticking to the ground).
I bled the system and changed the fluid and it didnt do much. Then I replaced the slave and used dot 5 fluid completly draining the old stuff. Now I just changed the master and used the Gunk dot 5 fluid and its doing the same ****. Could the dot 5 fluid be the culprit here? Should I switch to dot 4?
Any input would be great, cause Im about to put a wrench through my windshield. The car pulls great, but then I have to wait to get feeling in the clutch pedal before I can shift.

did you completely drain the DOT3 out of your system before you started filling it will DOT5?
you might be replacing your hydrolics again, if you do, just keep DOT3 in it (and don't use fluid from a bottle that has been opened before).

Not a good idea to switch it over to DOT 5. Silicone based DOT 5 fluids are chemically different and incompatible with glyocl based DOT 3, 4, and 5.1 fluids. Silicone DOT 5 is also more compressible thant glycol based fluids and the seals and hoses in the clutch system were not designed with it in mind. In all practicality almost every major fluid manufacturer that rate their fluid as DOT 3 is doing so despite the fact that most exceed even DOT 4 specs for boiling point and compressibility. Effectively by switching to silicone DOT 5 you're contaminating the system, putting in a "squishier" fluid, not gaining much for boiling point than you would get with a DOT 4 rated glycol fluid. If you're really worried about boiling point and want to be sure you compensate for it, then what you want is DOT 5.1 glycol based fluid. It will give you less compressibility, chemical compatibility with the system, and a higher boiling point than DOT 5. The downside being that it will absorb water more readily, and is more damaging to paint and plastic surfaces around it.
Don't mean to get too technical, but thought I'd give you the info and let you decide. Hope it helps.
