Symptoms of having the wrong sized Master Cylinder?

[jlwdvm]

What would be the symptoms of having a master cylinder that is the wrong size? I have a manual Wilwood 7/8" (rebuilt by Wilwood) on my project with Aerolites front and rear, all new copper lines, stainless flex lines, bled...driven...bled...driven, vacuum bled, reverse bled, pedal pump bled, pads bedded, etc. It just seems like the brakes don't wake up unless I really slam on them with my foot...almost like I have to think ahead about stopping when I am driving around town. I have a '15 Z/28 and a '17GT350R and the slightest touch of the pedal gets an immediate response (granted they are power brake cars). I'm just not sure what a manual brake car is supposed to feel like. I can get the brakes to lock up if I really slam on them. Thoughts?
