I am picking up a 1983 4 cylinder car. I am planning on converting it to a 302. For the brakes I have a set of 91 v8 spindles. My plan is to upgrade the fronts to the 91 v8 spindles and brakes. As for the master cylinder would it make more sense to use a 91 master cylinder and prop valve since the 91 has 3 ports. If I get a complete brake line set this seems like it would be rather easy. I also will be switching out the 7.5 for a 8.8 rear. Just looking for some advice. Thanks !
