Hello fellas, I have a 1970. Its a malibu ss clone with a 454. It has 4 drums now but I am going to upgrade to 4 discs. Was wondering what is the max size booster I can fit with this setup. I hope to get answers from similar owners, but ideas are also appreciated. Not really looking to go the hydraulic route from the power steering or dual diaphram because I was looking at a complete package from CPP.
