No, the POL uses your existing MC, no additional lines needed. You will need a 10# residual pressure valve in the line going to the rear brakes and remove the residual valve in the master cylinder. Took about 3 hours to install the kit. Took more time bleeding the brakes. Wife said her leg was getting tired.
There is no hydraulic difference between a single or dual master. The dual is strictly a federally mandated safety change from 1967. The only thing that effects your braking is the bore size of a master cylinder.
I like using the original master unless doing a total frame off type of build where it is of no difference to split the lines. There are some that feel their life is in danger with a single master
, I'm not one of those.
You do have to remove the residual pressure valve from inside the master when using any drum brake master for disc brakes. Easy to do, remove round disc(2178) with small holes from front of return spring and reassemble without.
As far as a prop valve, you only need one if your rear brakes lock up before the fronts excessively, may or may not. If it does you can add an adjustable valve to the rear brake line.

Thanks for that Mike. Let me throw one more thing into the ring. My present brake set up is stock with the exception that I have added a separate brake booster. So, the fluid goes from my master cylinder through pipes to the brake booster and then into the brake lines. Does this configuration alter any of what you have said above?

Not sure what you have done, but at some point the master has to feed the brakes, if it has a residual pressure valve, remove it for disc brake operation
May I throw another question out here. The conversion kits say they move the tires out some. This one is the smallest at 3/4 of an inch.
What does this do to the stock rims I have ? Does it move the tires too close to the fender ? I already have a scraping problem.
Been doing research the last couple of days.
Corvette America moves wheels out 1 1/4"
Corvette Central 1"
Performance Online 3/4"
Performance Online ( Wilwood ) .27" A little more than 1/4"
Jegs ( Wilwood ) .27"
Summit Racing ( Wilwood ) .27"
