Man, I really don't know. LOL

I bled EACH caliper at least 5 times with a vacula, then my hand with a 2nd person (old fashioned way), and then with the 1 man bleeder bottle with help again. I don't see anymore bubbles coming out. So I just ASSUMED there was no air because hell it should have came out by now I thought. If I couldn't get it out that many times, I figured it will never come out so it's GOTTA be clear.

I'm going to bench bleed the master though because while I had it hooked up to the booster , I left it unplugged while I was flaring some new fittings. It's possible air got back in the MC. Thanks for replying to my email too bro. I will try that, then if it's fine, I'll just install the new Raybestos premium 79 new MC I just ordered. My Camaro used the same MC and went like a BREEZE the 1st time around. This one is being a real bitch to me.

BTW what did you mean by "A single master cylinder" ??
The 79 Vette MC has 2 equal size chambers and is 1 1/8".....so you lost me. I'm still kinda new to this so excuse my ignorance.
