    Red face What Kind of vacums can I expect SB350

     



    I' m building a sb 350 10 over, I installed a crane cam with a 218 dur and .450 lift, 64cc iron heads w/202/160 valves, Edel performer RPM intake and a edle 1407 750 cfm carb. My question is , Will I have good vacum for the power brakes. A friend of mine said that the cam is so big I will have about 5 psi manifold vacum. ????? I'm sure with all the experienced engine builders out there, someone will give me the awnser I need, weather its the one I want to hear or not. All advice will be appreciated.:
