ok talking about a 305sbc. my th350 needs vacuum as does my power brake booster. i am only aware of 2 ports to get vacuum from. 1 is the carb base. I was told this was varible and i dont want to use this for my power booster. the other port is behind the carb on the manifold between the distributer and carb. the rear port is hooked into my th350.
what is the proper way to hook both the transmission and the booster up and which ports? should i t off the rear port for both?
thanks in advance
