C5 C6 setup questions??

[80z28s6]

Got an 80 Z28 with stock 11"front and 99 LS1 rears. Have a 79-80 4 disk master(power, no manual brakes) with prop valve. Want to put C5 or C6 brakes up front. Do I need to change anything with the master or prop valve? Thanks Rick

Yes, you will want to change the MC to a smaller bore size. The OE MC you have should be 1-1/8" bore and you'll want something closer to 1" with a good functioning vacuum booster. The OE prop valve may work out fine for you and it can't hurt to try it out, however in my experience you can usually tolerate more rear brake and suggest running an adjustable prop valve instead.

Any recomendations for a master that would work with my booster(80z28).
Thanks again
